This type of assault could be very horrifying, who where we take it into consideration in the course of the design system. While designing a building, now not only the wind and seismic masses however also the consequences of the blast have to be take into consideration. Blast load is the burden implemented to a structure form a blast wave that comes straight away after an explosion. A blast in or close to a constructing can reason catastrophic harm to the interior and exterior of the building, inner structural framework, wall collapsing, and so on. The most important feature of blast resistant construction is the ability to absorb blast energy without causing catastrophic failure of the structure as a whole. Construction materials in blastprotective structures must have ductility as well as strength. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=blast%20resistant%20design" title="blast resistant design">blast resistant design</a>, <a href="https://publications.waset.org/abstracts/search?q=blast%20load" title=" blast load"> blast load</a>, <a href="https://publications.waset.org/abstracts/search?q=explosion" title=" explosion"> explosion</a>, <a href="https://publications.waset.org/abstracts/search?q=ETABS" title=" ETABS"> ETABS</a> </p> <a href="https://publications.waset.org/abstracts/158203/a-review-on-design-and-analysis-of-structure-against-blast-forces" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/158203.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">103</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3433</span> Blast Load Resistance of Bridge Columns</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amir%20Kavousifard">Amir Kavousifard</a>, <a href="https://publications.waset.org/abstracts/search?q=Lan%20Lin"> Lan Lin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The objective of this study is to evaluate the effects of the detailing in the seismic design of reinforced concrete (RC) bridge columns on the blast load resistance. A generic two-span continuous RC bridge located in Victoria, British Columbia, which represents the highest seismicity in Canada, was examined in the study. The bridge superstructure consists of a single cell box girder while the substructure consists of two circular columns. The bridge was designed according to the 2006 Canadian Highway Bridge Design Code. More specifically, response spectrum analysis was performed to determine the seismic demands using CSI Bridge. The 3D blast load analysis is carried out in the platform of LS-DYNA. Two charge heights, i.e., one at the mid-height of the column and the other at the bottom of the column, are considered. For each height, three cases are analyzed in order to investigate the effects of standoff and charge weight on the structural response. The blast load resistance of the column is assessed in terms of the concrete failure mechanism, steel stress distribution, and column lateral displacement. The results from the study indicate that a column designed in accordance with the code requirements could survive during the blast attack. Spiral columns perform much better than tied columns. The results also show that the charge weight has more impact on the structural response than the standoff. These results are beneficial for the development of the Canadian standards for the design of bridges under blast loads. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=blast" title="blast">blast</a>, <a href="https://publications.waset.org/abstracts/search?q=bridge" title=" bridge"> bridge</a>, <a href="https://publications.waset.org/abstracts/search?q=charge" title=" charge"> charge</a>, <a href="https://publications.waset.org/abstracts/search?q=height" title=" height"> height</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic" title=" seismic"> seismic</a>, <a href="https://publications.waset.org/abstracts/search?q=standoff" title=" standoff"> standoff</a> </p> <a href="https://publications.waset.org/abstracts/190131/blast-load-resistance-of-bridge-columns" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/190131.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">19</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3432</span> Freeze-Thaw Resistance of Concretes with BFSA</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alena%20Sicakova">Alena Sicakova</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Air-cooled Blast furnace slag aggregate (BFSA) is usually referred to as a material providing for unique properties of concrete. On the other hand, negative influences are also presented in many aspects. The freeze-thaw resistance of concrete is dependent on many factors, including regional specifics and when a concrete mix is specified it is still difficult to tell its exact freeze-thaw resistance due to the different components affecting it. An important consideration in working with BFSA is the granularity and whether slag is sorted or not. The experimental part of the article represents a comparative testing of concrete using both the sorted and unsorted BFSA through the freeze-thaw resistance as an indicator of durability. Unsorted BFSA is able to be successfully used for concretes as they are specified for exposure class XF4 with providing that the type of cement is precisely selected. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=blast%20furnace%20slag%20aggregate" title="blast furnace slag aggregate">blast furnace slag aggregate</a>, <a href="https://publications.waset.org/abstracts/search?q=concrete" title=" concrete"> concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=freeze-thaw%20resistance" title=" freeze-thaw resistance"> freeze-thaw resistance</a> </p> <a href="https://publications.waset.org/abstracts/28622/freeze-thaw-resistance-of-concretes-with-bfsa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28622.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">396</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3431</span> Effect of Blast Loads on the Seismically Designed Reinforced Concrete Buildings</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jhuma%20Debnath">Jhuma Debnath</a>, <a href="https://publications.waset.org/abstracts/search?q=Hrishikesh%20Sharma"> Hrishikesh Sharma</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The work done here in this paper is dedicated to studying the effect of high blast explosives over the seismically designed buildings. Buildings are seismically designed in SAP 2000 software to simulate seismic designs of buildings using response spectrum method. Later these buildings have been studied applying blast loads with the same amount of the blast explosives. This involved varying the standoff distances of the buildings from the blast explosion. The study found out that, for a seismically designed building, the minimum standoff distance is to be at least 120m from the place of explosion for an average blast explosive weight of 20kg TNT. This has shown that the building does not fail due to this huge explosive weight of TNT but resists immediate collapse of the building. The results also show that the adverse effect of the column failure due to blasting is reduced to 73.75% from 22.5% due to the increase of the standoff distance from the blast loads. The maximum affected locations due to the blast loads are also detected in this study. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=blast%20loads" title="blast loads">blast loads</a>, <a href="https://publications.waset.org/abstracts/search?q=seismically%20designed%20buildings" title=" seismically designed buildings"> seismically designed buildings</a>, <a href="https://publications.waset.org/abstracts/search?q=standoff%20distance" title=" standoff distance"> standoff distance</a>, <a href="https://publications.waset.org/abstracts/search?q=reinforced%20concrete%20buildings" title=" reinforced concrete buildings"> reinforced concrete buildings</a> </p> <a href="https://publications.waset.org/abstracts/98209/effect-of-blast-loads-on-the-seismically-designed-reinforced-concrete-buildings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/98209.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">235</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3430</span> The Study on Treatment Technology of Fused Carbonized Blast Furnace Slag</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jiaxu%20Huang">Jiaxu Huang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The melt carbonized blast furnace slag containing TiC was produced by carbothermal reduction of high titanium blast furnace slag. The treatment technology of melt carbonized blast furnace slag with TiC as raw material was studied, including the influence of different cooling methods, crushing atmosphere and sieving particle size on the target product TiC in the slag. The results show that air-cooling and water-cooling have little effect on TiC content of molten carbide blast furnace slag, and have great effect on crystal structure and grain size. TiC content in slag is different when carbide blast furnace slag is crushed in argon atmosphere and air atmosphere. After screening, the difference of TiC content of carbide blast furnace slag with different particle size distribution is obvious. The average TiC content of 100-400 mesh carbide blast furnace slag is 14%.

In any infrastructure system, the structural elements like lower floors, exterior columns, walls etc. are key elements which are the most susceptible to damage due to blast load. The present study revisits the state of art review of the design and analysis of reinforced concrete panels subjected to blast loading. Various aspects in association with blast loading on structure, i.e. estimation of blast load, experimental works carried out previously, the numerical simulation tools, various material models, etc. are considered for exploring the current practices adopted worldwide. Discussion on various parametric studies to investigate the effect of reinforcement ratios, thickness of slab, different charge weight and standoff distance is also made. It was observed that for the simulation of blast load, CONWEP blast function or equivalent numerical equations were successfully employed by many researchers. The study of literature indicates that the researches were carried out using experimental works and numerical simulation using well known generalized finite element methods, i.e. LS-DYNA, ABAQUS, AUTODYN. Many researchers recommended to use concrete damage model to represent concrete and plastic kinematic material model to represent steel under action of blast loads for most of the numerical simulations. Most of the studies reveal that the increase reinforcement ratio, thickness of slab, standoff distance was resulted in better blast resistance performance of reinforced concrete panel. The study summarizes the various research results and appends the present state of knowledge for the structures exposed to blast loading. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=blast%20phenomenon" title="blast phenomenon">blast phenomenon</a>, <a href="https://publications.waset.org/abstracts/search?q=experimental%20methods" title=" experimental methods"> experimental methods</a>, <a href="https://publications.waset.org/abstracts/search?q=material%20models" title=" material models"> material models</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20methods" title=" numerical methods"> numerical methods</a> </p> <a href="https://publications.waset.org/abstracts/96432/the-current-practices-of-analysis-of-reinforced-concrete-panels-subjected-to-blast-loading" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/96432.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">157</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3428</span> The Effect of Traffic Load on the Maximum Response of a Cable-Stayed Bridge under Blast Loads</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20K.%20Hashemi">S.

The air blast generated by the explosion of bombs or fuel tankers leads to high-magnitude short-duration loading scenarios that can cause severe structural damage and loss of critical structural members. Hence, more attentions need to put towards bridge structures to develop guidelines to increase the resistance of such structures against the probable blast. Recent advancements in numerical methods have brought about the viable and cost effective facilities to simulate complicated blast scenarios and subsequently provide useful reference for safeguarding design of critical infrastructures. In the previous studies common bridge responses to blast load, the traffic load is sometimes not included in the analysis. Including traffic load will increase the axial compression in bridge piers especially when the axial load is relatively small. Traffic load also can reduce the uplift of girders and deck when the bridge experiences under deck explosion. For more complicated structures like cable-stayed or suspension bridges, however, the effect of traffic loads can be completely different. The tension in the cables increase and progressive collapse is likely to happen while traffic loads exist. Accordingly, this study is an attempt to simulate the effect of traffic load cases on the maximum local and global response of an entire cable-stayed bridge subjected to blast loadings using LS-DYNA explicit finite element code. The blast loads ranged from small to large explosion placed at different positions above the deck. Furthermore, the variation of the traffic load factor in the load combination and its effect on the dynamic response of the bridge under blast load is investigated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=blast" title="blast">blast</a>, <a href="https://publications.waset.org/abstracts/search?q=cable-stayed%20bridge" title=" cable-stayed bridge"> cable-stayed bridge</a>, <a href="https://publications.waset.org/abstracts/search?q=LS-DYNA" title=" LS-DYNA"> LS-DYNA</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical" title=" numerical"> numerical</a>, <a href="https://publications.waset.org/abstracts/search?q=traffic%20load" title=" traffic load"> traffic load</a> </p> <a href="https://publications.waset.org/abstracts/32906/the-effect-of-traffic-load-on-the-maximum-response-of-a-cable-stayed-bridge-under-blast-loads" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32906.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">332</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3427</span> Full Analytical Procedure to Derive P-I Diagram of a Steel Beam under Blast Loading</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=L.%20Hamra">L.

We develop a full analytical procedure that provides the ductility demand as a function of these six dimensionless parameters. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=analytical%20procedure" title="analytical procedure">analytical procedure</a>, <a href="https://publications.waset.org/abstracts/search?q=blast%20loading" title=" blast loading"> blast loading</a>, <a href="https://publications.waset.org/abstracts/search?q=membrane%20force" title=" membrane force"> membrane force</a>, <a href="https://publications.waset.org/abstracts/search?q=P-I%20diagram" title=" P-I diagram"> P-I diagram</a> </p> <a href="https://publications.waset.org/abstracts/13731/full-analytical-procedure-to-derive-p-i-diagram-of-a-steel-beam-under-blast-loading" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13731.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">427</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3426</span> Significant Reduction in Specific CO₂ Emission through Process Optimization at G Blast Furnace, Tata Steel Jamshedpur</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shoumodip%20Roy">Shoumodip Roy</a>, <a href="https://publications.waset.org/abstracts/search?q=Ankit%20Singhania"> Ankit Singhania</a>, <a href="https://publications.waset.org/abstracts/search?q=M.%20K.%20G.%20Choudhury"> M.

Decreasing specific CO₂ emission is one of the key steps to achieve the stated corporate goal. At any Blast Furnace, specific CO₂ emission is directly proportional to fuel intake. To reduce the fuel intake at G Blast Furnace, an initial benchmarking exercise was carried out with international and domestic Blast Furnaces to determine the potential for improvement. The gap identified during the exercise revealed that the benchmark Blast Furnaces operated with superior raw material quality than that in G Blast Furnace. However, since the raw materials to G Blast Furnace are sourced from the captive mines, improvement in the raw material quality was out of scope. Therefore, trials were taken with different operating regimes, to identify the key process parameters, which on optimization could significantly reduce the fuel intake in G Blast Furnace. The key process parameters identified from the trial were the Stoichiometric Oxygen Ratio, Melting Capacity ratio and the burden distribution inside the furnace. These identified process parameters were optimized to bridge the gap in fuel intake at G Blast Furnace, thereby reducing specific CO₂ emission to benchmark levels. This paradigm shift enabled to lower the fuel intake by 70kg per ton of liquid iron produced, thereby reducing the specific CO₂ emission by 15 percent. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=benchmark" title="benchmark">benchmark</a>, <a href="https://publications.waset.org/abstracts/search?q=blast%20furnace" title=" blast furnace"> blast furnace</a>, <a href="https://publications.waset.org/abstracts/search?q=CO%E2%82%82%20emission" title=" CO₂ emission"> CO₂ emission</a>, <a href="https://publications.waset.org/abstracts/search?q=fuel%20rate" title=" fuel rate"> fuel rate</a> </p> <a href="https://publications.waset.org/abstracts/74952/significant-reduction-in-specific-co2-emission-through-process-optimization-at-g-blast-furnace-tata-steel-jamshedpur" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/74952.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">280</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3425</span> Effects of Blast Load on Historic Stone Masonry Buildings in Canada: A Review and Analytical Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abass%20Braimah">Abass Braimah</a>, <a href="https://publications.waset.org/abstracts/search?q=Maha%20Hussein%20Abdallah"> Maha Hussein Abdallah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The global ascendancy of terrorist attacks on building infrastructure with economic and heritage significance has increased awareness of the possibility of terrorism in Canada. Many structures in Canada that are at risk of terrorist attacks include government buildings, built many years ago of historic stone masonry construction. Although many researchers are investigating ways to retrofit masonry stone buildings to mitigate the effect of blast loadings, lack of knowledge on the dynamic behavior of historic stone masonry structures under blast loads makes it difficult to ascertain the effectiveness of the retrofitting techniques. This paper presents a review of open-source literature for the experimental and numerical stone masonry structures under blast loads. This review yielded very little information of the response of the historic stone masonry structures under blast loads. Thus, a comprehensive study is needed to understand the blast load effects on historic stone masonry buildings. The out-of-plane response of historic masonry structures to blast loads is investigated by using single-degree-of-freedom analysis. This approach presents equations that can be used effectively in the analysis of historic masonry walls to out-of-plane blast loading. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=blast%20loads" title="blast loads">blast loads</a>, <a href="https://publications.waset.org/abstracts/search?q=historical%20buildings" title=" historical buildings"> historical buildings</a>, <a href="https://publications.waset.org/abstracts/search?q=masonry%20structure" title=" masonry structure"> masonry structure</a>, <a href="https://publications.waset.org/abstracts/search?q=single-degree-of-freedom%20analysis" title=" single-degree-of-freedom analysis"> single-degree-of-freedom analysis</a> </p> <a href="https://publications.waset.org/abstracts/129638/effects-of-blast-load-on-historic-stone-masonry-buildings-in-canada-a-review-and-analytical-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/129638.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">184</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3424</span> Development of Environmentally Clean Construction Materials Using Industrial Waste from Kazakhstan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Galiya%20Zhanzakovna%20Alzhanova">Galiya Zhanzakovna Alzhanova</a>, <a href="https://publications.waset.org/abstracts/search?q=Yelaman%20Kanatovich%20Aibuldinov"> Yelaman Kanatovich Aibuldinov</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhanar%20Baktybaevna%20Iskakova"> Zhanar Baktybaevna Iskakova</a>, <a href="https://publications.waset.org/abstracts/search?q=Gaziz%20Galymovich%20Abdiyussupov">Gaziz Galymovich Abdiyussupov</a>, <a href="https://publications.waset.org/abstracts/search?q=Madi%20Toktasynuly%20Omirzak"> Madi Toktasynuly Omirzak</a>, <a href="https://publications.waset.org/abstracts/search?q=Aizhan%20Doldashevna%20Gazizova"> Aizhan Doldashevna Gazizova</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The sustainable use of industrial waste has recently increased due to increased environmental problems in landfills. One of the best ways to utilise waste is as a road base material. Industrial waste is a less costly and more efficient way to strengthen local soils than by introducing new additive materials. This study explored the feasibility of utilising red mud, blast furnace slag, and lime production waste to develop environmentally friendly construction materials for stabilising natural loam. Four different ratios of red mud (20, 30, and 40%), blast furnace slag (25, 30, and 35%), lime production waste (4, 6, and 8%), and varied amounts of natural loam were combined to produce nine different mixtures. The results showed that the sample with 40% red mud, 35% blast furnace slag, and 8% lime production waste had the highest strength. The sample's measured compressive strength for 90 days was 7.38 MPa, its water resistance for the same period was 7.12 MPa, and its frost resistance for the same period was 7.35 MP; low linear expansion met the requirements of the Kazakh regulations for first-class building materials. The study of mineral composition showed that there was no contamination with heavy metals or dangerous substances. Road base materials made of red mud, blast furnace slag, lime production waste, and natural loam mix can be employed because of their durability and environmental performance. The chemical and mineral composition of raw materials was determined using X-ray diffraction, X-ray fluorescence, scanning electron microscopy, energy dispersive spectroscopy, atomic absorption spectroscopy, and axial compressive strength were examined. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=blast%20furnace%20slag" title="blast furnace slag">blast furnace slag</a>, <a href="https://publications.waset.org/abstracts/search?q=lime%20production%20waste" title=" lime production waste"> lime production waste</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20loam%20stabilizing" title=" natural loam stabilizing"> natural loam stabilizing</a>, <a href="https://publications.waset.org/abstracts/search?q=red%20mud" title=" red mud"> red mud</a>, <a href="https://publications.waset.org/abstracts/search?q=road%20base%20material" title=" road base material"> road base material</a> </p> <a href="https://publications.waset.org/abstracts/158206/development-of-environmentally-clean-construction-materials-using-industrial-waste-from-kazakhstan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/158206.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">110</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3423</span> Construction of India’s Largest Blast Furnace (4554 cum) Foundation at JSPL, Angul, Odisha: A Qualitative Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20S.%20S.%20Rao">N.

Lower hot metal silicon not only enhances process efficiency at steel melting shops but also reduces hot metal costs. The Hot metal produced at G-Blast furnace Tata Steel Jamshedpur has a significantly higher Si content than Benchmark Blast furnaces. The higher content of hot metal Si is mainly due to inferior raw material quality than those used in benchmark blast furnaces. With minimum control over raw material quality, the only option left to control hot metal Si is via optimizing the furnace parameters. Therefore, in order to identify the levers to reduce hot metal Si, Data mining was carried out, and multiple regression models were developed. The statistical analysis revealed that Slag B3{(CaO+MgO)/SiO2}, Slag Alumina and Hot metal temperature are key controllable parameters affecting hot metal silicon. Contour Plots were used to determine the optimum range of levels identified through statistical analysis. A trial plan was formulated to operate relevant parameters, at G blast furnace, in the identified range to reduce hot metal silicon. This paper details out the process followed and subsequent reduction in hot metal silicon by 15% at G blast furnace. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=blast%20furnace" title="blast furnace">blast furnace</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization" title=" optimization"> optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=silicon" title=" silicon"> silicon</a>, <a href="https://publications.waset.org/abstracts/search?q=statistical%20tools" title=" statistical tools"> statistical tools</a> </p> <a href="https://publications.waset.org/abstracts/74955/reduction-in-hot-metal-silicon-through-statistical-analysis-at-g-blast-furnace-tata-steel-jamshedpur" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/74955.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">223</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3421</span> Analysis of the Behavior of the Structure Under Internal Anfo Explosion</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seung-Min%20Ko">Seung-Min Ko</a>, <a href="https://publications.waset.org/abstracts/search?q=Seung-Jai%20Choi"> Seung-Jai Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Gun%20Jung"> Gun Jung</a>, <a href="https://publications.waset.org/abstracts/search?q=Jang-Ho%20Jay%20Kim"> Jang-Ho Jay Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Although extensive explosion-related research has been performed in the past several decades, almost no research has focused on internal blasts. However, internal blast research is needed to understand about the behavior of a containment structure or building under internal blast loading, as in the case of the Chornobyl and Fukushima nuclear accidents. Therefore, the internal blast study concentrated on RC and PSC structures is performed. The test data obtained from reinforced concrete (RC) and prestressed concrete (PSC) tubular structures applied with an internal explosion using ammonium nitrate/fuel oil (ANFO) charge are used to assess their deformation resistance and ultimate failure load based on the structural stiffness change under various charge weight. For the internal blast charge weight, ANFO explosive charge weights of 15.88, 20.41, 22.68 and 24.95 kg were selected for the RC tubular structures, and 22.68, 24.95, 27.22, 29.48, and 31.75 kg were selected for PSC tubular structures, which were detonated at the center of cross section at the mid-span with a standoff distance of 1,000mm to the inner wall surface. Then, the test data were used to predict the internal charge weight required to fail a real scale reinforced concrete containment vessels (RCCV) and prestressed concrete containment vessel (PCCV). Then, the analytical results based on the experimental data were derived using the simple assumptions of the models, and another approach using the stiffness, deformation and explosion weight relationship was used to formulate a general method for analyzing internal blasted tubular structures. A model of the internal explosion of a steel tube was used as an example for validation. The proposed method can be used generically, using factors according to the material characteristics of the target structures. The results of the study are discussed in detail in the paper. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=internal%20blast" title="internal blast">internal blast</a>, <a href="https://publications.waset.org/abstracts/search?q=reinforced%20concrete" title=" reinforced concrete"> reinforced concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=RCCV" title=" RCCV"> RCCV</a>, <a href="https://publications.waset.org/abstracts/search?q=PCCV" title=" PCCV"> PCCV</a>, <a href="https://publications.waset.org/abstracts/search?q=stiffness" title=" stiffness"> stiffness</a>, <a href="https://publications.waset.org/abstracts/search?q=blast%20safety" title=" blast safety"> blast safety</a> </p> <a href="https://publications.waset.org/abstracts/179251/analysis-of-the-behavior-of-the-structure-under-internal-anfo-explosion" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/179251.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">79</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3420</span> Numerical Investigation of Fiber-Reinforced Polymer (FRP) Panels Resistance to Blast Loads</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sameh%20Ahmed">Sameh Ahmed</a>, <a href="https://publications.waset.org/abstracts/search?q=Khaled%20Galal"> Khaled Galal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Fiber-reinforced polymer (FRP) sandwich panels are increasingly making their way into structural engineering applications. One of these applications is the blast mitigation. This is attributed to FRP ability of absorbing considerable amount of energy relative to their low density. In this study, FRP sandwich panels are numerically studied using an explicit finite element code ANSYS AUTODYN. The numerical model is then validated with the experimental field tests in the literature. The inner core configurations that have been studied in the experimental field tests were formed from different orientations of the honeycomb shape. On the other hand, the conducted numerical study has proposed a new core configuration. The new core configuration is formulated from a combination of woven and honeycomb shapes. Throughout this study, two performance parameters are considered; the amount of the energy absorbed by the panels and the peak deformation of the panels. Following, a parametric study has been conducted with more variations of the studied parameters to examine the enhancement of the panels' performance. It is found that the numerical results have shown a good agreement with the experimental measurements. Furthermore, the analyses have revealed that using the proposed core configuration obviously enhances the FRP panels’ behavior when subjected to blast loads. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=blast%20load" title="blast load">blast load</a>, <a href="https://publications.waset.org/abstracts/search?q=fiber%20reinforced%20polymers" title=" fiber reinforced polymers"> fiber reinforced polymers</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20modeling" title=" finite element modeling"> finite element modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=sandwich%20panels" title=" sandwich panels"> sandwich panels</a> </p> <a href="https://publications.waset.org/abstracts/40612/numerical-investigation-of-fiber-reinforced-polymer-frp-panels-resistance-to-blast-loads" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40612.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">312</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3419</span> Multiscale Model of Blast Explosion Human Injury Biomechanics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Raj%20K.%20Gupta">Raj K.

This paper presents a multiscale computational model of coupled blast physics, whole human body biodynamics and injury biomechanics of sensitive organs. The disparity of the involved space- and time-scales is used to conduct sequential modeling of an IED explosion event, CFD simulation of blast loads on the human body and FEM modeling of body biodynamics and injury biomechanics. The paper presents simulation results for blast-induced brain injury coupling macro-scale brain biomechanics and micro-scale response of sensitive neuro-axonal structures. Validation results on animal models and physical surrogates are discussed.

It is observed that the presence of dust particles in the gas yields more complex expression as compared to the ordinary Gasdynamics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=shock%20wave" title="shock wave">shock wave</a>, <a href="https://publications.waset.org/abstracts/search?q=blast%20wave" title=" blast wave"> blast wave</a>, <a href="https://publications.waset.org/abstracts/search?q=dusty%20gas" title=" dusty gas"> dusty gas</a>, <a href="https://publications.waset.org/abstracts/search?q=strong%20shock" title=" strong shock"> strong shock</a> </p> <a href="https://publications.waset.org/abstracts/64918/solution-of-the-blast-wave-problem-in-dusty-gas" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/64918.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">332</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3417</span> Extension of D Blast Furnace Campaign Life at Tata Steel Ltd</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Biswajit%20Seal">Biswajit Seal</a>, <a href="https://publications.waset.org/abstracts/search?q=Dushyant%20Kumar"> Dushyant Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Shambhu%20Nath"> Shambhu Nath</a>, <a href="https://publications.waset.org/abstracts/search?q=A.%20B.%20Raju"> A.

Tata Steel Ltd, Jamshedpur plant operates seven blast furnaces with combination of old and new technologies. The focus of Tata Steel Ltd is to push for increasing productivity with good quality product and increasing campaign life. This has been challenging for older furnaces because older furnaces are generally equipped with less automation, old design and old equipment. Good operational practices, appropriate remedial measures, and regular planned maintenance helps to achieve long campaign life of old furnaces. Good operating practices like stable and consistent productivity, control of burden distribution, remedial measures like stack gunning and shotcreting for protection of stack wall, enhanced cooling system, and intermediate stack repair helps to achieve long campaign life of old blast furnaces. This paper describes experiences with the current old equipment and design of Tata Steel’s D Blast Furnace for campaign life extension. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=blast%20furnace" title="blast furnace">blast furnace</a>, <a href="https://publications.waset.org/abstracts/search?q=burden%20distribution" title=" burden distribution"> burden distribution</a>, <a href="https://publications.waset.org/abstracts/search?q=campaign%20life" title=" campaign life"> campaign life</a>, <a href="https://publications.waset.org/abstracts/search?q=productivity" title=" productivity"> productivity</a> </p> <a href="https://publications.waset.org/abstracts/75455/extension-of-d-blast-furnace-campaign-life-at-tata-steel-ltd" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75455.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">261</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3416</span> An Analysis of the Results of Trial Blasting of Site Development Project in the Volcanic Island</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dong%20Wook%20Lee">Dong Wook Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Seung%20Hyun%20Kim"> Seung Hyun Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Trial blasting is conducted to identify the characteristics of the blasting of the applicable ground before production blasting and to investigate various problems posed by blasting. The methods and pattern of production blasting are determined based on an analysis of the results of trial blasting. The bedrock in Jeju Island, South Korea is formed through the volcanic activities unlike the inland areas, composed of porous basalt. Trial blasting showed that the blast vibration frequency of sedimentary and metamorphic rocks in the inland areas is in a high frequency band of about 80 Hz while the blast vibration frequency of Jeju Island is in a low frequency band of 10~25 Hz. The frequency band is analyzed to be low due to the large cycle of blasting pattern as blast vibration passes through the layered structured ground layer where the rock formation and clickers irregularly repeat. In addition, the blast vibration equation derived from trial blasting was R: 0.885, S.E: 0.216 when applying the square root scaled distance (SRSD) relatively suitable for long distance, estimated at the confidence level of 95%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=attenuation%20index" title="attenuation index">attenuation index</a>, <a href="https://publications.waset.org/abstracts/search?q=basaltic%20ground" title=" basaltic ground"> basaltic ground</a>, <a href="https://publications.waset.org/abstracts/search?q=blast%20vibration%20constant" title=" blast vibration constant"> blast vibration constant</a>, <a href="https://publications.waset.org/abstracts/search?q=blast%20vibration%20equation" title=" blast vibration equation"> blast vibration equation</a>, <a href="https://publications.waset.org/abstracts/search?q=clinker%20layer" title=" clinker layer"> clinker layer</a> </p> <a href="https://publications.waset.org/abstracts/54595/an-analysis-of-the-results-of-trial-blasting-of-site-development-project-in-the-volcanic-island" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54595.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">280</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3415</span> Safety of Built Infrastructure: Single Degree of Freedom Approach to Blast Resistant RC Wall Panels</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muizz%20Sanni-Anibire">Muizz Sanni-Anibire</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The 21st century has witnessed growing concerns for the protection of built facilities against natural and man-made disasters. Studies in earthquake resistant buildings, fire, and explosion resistant buildings now dominate the arena. To protect people and facilities from the effects of the explosion, reinforced concrete walls have been designed to be blast resistant. Understanding the performance of these walls is a key step in ensuring the safety of built facilities. Blast walls are mostly designed using simple techniques such as single degree of freedom (SDOF) method, despite the increasing use of multi-degree of freedom techniques such as the finite element method. This study is the first stage of a continuous research into the safety and reliability of blast walls. It presents the SDOF approach applied to the analysis of a concrete wall panel under three representative bomb situations. These are motorcycle 50 kg, car 400kg and also van with the capacity of 1500 kg of TNT explosive. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=blast%20wall" title="blast wall">blast wall</a>, <a href="https://publications.waset.org/abstracts/search?q=safety" title=" safety"> safety</a>, <a href="https://publications.waset.org/abstracts/search?q=protection" title=" protection"> protection</a>, <a href="https://publications.waset.org/abstracts/search?q=explosion" title=" explosion"> explosion</a> </p> <a href="https://publications.waset.org/abstracts/65519/safety-of-built-infrastructure-single-degree-of-freedom-approach-to-blast-resistant-rc-wall-panels" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65519.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">263</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3414</span> Preparation and Characterization of Road Base Material Based on Kazakhstan Production Waste</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20K.%20Kaidarova">K.

The solution to this problem can be achieved by replacing traditional building materials with industrial waste, which in their chemical and mineralogical composition are close to natural raw materials and can partially or completely replace some natural binding materials in road construction. In this regard, the purpose of this study is to develop building materials based on the red sludge of the Pavlodar aluminum plant, blast furnace slag of the Karaganda Metallurgical Plant, lime production waste of the Pavlodar Aluminum Plant as a binder for natural loam. Changes in physical and mechanical properties were studied for uniaxial compression strength, linear expansion coefficient, water resistance, and frost resistance of the samples. Nine mixtures were formed with different percentages of these wastes 1-20:25:4; 2-20:25:6; 3-20:25:8; 4-30:30:4; 5-30:30:6; 6-30:30:8; 7-40:35:4; 8-40:35:6; 9-40:35:8 and the mixture identifier were labeled based on the waste content and composition number. The results of strength measurement during uniaxial compression of the samples showed an almost constant increase in strength and amounted to 0.67–3.56 MPa after three days and 3.33–7.38 MPa after 90 days. This increase in compressive strength is a consequence of the addition of lime and becomes more pronounced over time. The water resistance of the developed materials after 90 days was 7.12 MPa, and the frost resistance for the same period was 7.35 MPa. The maximum values of strength determination were shown by a sample of the composition 9-40:35:8. The study of the mineral composition showed that there was no contamination with heavy metals or dangerous substances. It was determined that road materials made of red sludge, blast furnace slag, lime production waste, and natural loam mixture could be used due to their strength indicators and environmental characteristics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=production%20waste" title="production waste">production waste</a>, <a href="https://publications.waset.org/abstracts/search?q=uniaxial%20compression" title=" uniaxial compression"> uniaxial compression</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20resistance%20of%20materials" title=" water resistance of materials"> water resistance of materials</a>, <a href="https://publications.waset.org/abstracts/search?q=frost%20resistance%20of%20samples" title=" frost resistance of samples"> frost resistance of samples</a> </p> <a href="https://publications.waset.org/abstracts/165638/preparation-and-characterization-of-road-base-material-based-on-kazakhstan-production-waste" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165638.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">119</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3413</span> Practical Guidelines for Utilizing WipFrag Software to Assess Oversize Blast Material Using Both Orthomosaic and Digital Images</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Blessing%20Olamide%20Taiwo">Blessing Olamide Taiwo</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrew%20Palangio"> Andrew Palangio</a>, <a href="https://publications.waset.org/abstracts/search?q=Chirag%20Savaliya"> Chirag Savaliya</a>, <a href="https://publications.waset.org/abstracts/search?q=Jenil%20Patel"> Jenil Patel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Oversized material resulting from blasting presents a notable drawback in the transportation of run-off-mine material due to increased expenses associated with handling, decreased efficiency in loading, and greater wear on digging equipment.

Tunnels are being used for the transportation of humans and goods from distance to distance. Terrorist attacks on underground structures such as tunnels have resulted in the improvement of design methodologies of tunnels. The design of underground tunnels must include anti-terror design parameters. The study has been carried out to analyse the rock tunnel when subjected to internal blast loading. The finite element analysis has been carried out for 30m by 30m of the cross-section of the tunnel and 35m length of extrusion of the rock tunnel model. The effect of tunnel diameter and overburden depth of tunnel has been studied under internal blast loading. Four different diameters of tunnel considered are 5m, 6m, 7m, and 8m, and four different overburden depth of tunnel considered are 5m, 7.5m, 10m, and 12.5m. The mohr-coulomb constitutive material model has been considered for the Quartzite rock. A concrete damage plasticity model has been adopted for concrete tunnel lining. For the trinitrotoluene (TNT) Jones-Wilkens-Lee (JWL) material model has been considered. Coupled-Eulerian-Lagrangian (CEL) approach for blast analysis has been considered in the present study. The present study concludes that a shallow tunnel having smaller diameter needs more attention in comparison to blast resistant design of deep tunnel having a larger diameter. Further, in the case of shallow tunnels, more bulging has been observed, and a more substantial zone of rock has been affected by internal blast loading. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20method" title="finite element method">finite element method</a>, <a href="https://publications.waset.org/abstracts/search?q=blast" title=" blast"> blast</a>, <a href="https://publications.waset.org/abstracts/search?q=rock" title=" rock"> rock</a>, <a href="https://publications.waset.org/abstracts/search?q=tunnel" title=" tunnel"> tunnel</a>, <a href="https://publications.waset.org/abstracts/search?q=CEL" title=" CEL"> CEL</a>, <a href="https://publications.waset.org/abstracts/search?q=JWL" title=" JWL"> JWL</a> </p> <a href="https://publications.waset.org/abstracts/115807/stability-analysis-of-rock-tunnel-subjected-to-internal-blast-loading" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/115807.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">147</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3410</span> Reduction of Content of Lead and Zinc from Wastewater by Using of Metallurgical Waste</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=L.%20Rozumov%C3%A1">L.

The blast furnace sludge was characterized by X-Ray diffraction, scanning electron microscopy, and XRFS spectroscopy. Sorption experiments were conducted in batch mode. The sorption of metal ions in the sludge was determined by correlation of adsorption isotherm models. The adsorption of lead and zinc ions was best fitted with Langmuir adsorption isotherms. The adsorption capacity of lead and zinc ions was 53.8 mg.g<sup>-1</sup> and 10.7 mg.g<sup>-1</sup>, respectively.

One of the major problems of blast furnace operation is the erratic burden descent inside furnace. Sometimes this problem is so acute that burden descent stops resulting in Hanging and instability of the furnace. This problem is very frequent in blast furnaces worldwide and results in huge production losses. This situation becomes more adverse when blast furnaces are operated at low coke rate and high coal injection rate with adverse raw materials like high alumina ore and high coke ash. For last three years, H-Blast Furnace Tata Steel was able to reduce coke rate from 450 kg/thm to 350 kg/thm with an increase in coal injection to 200 kg/thm which are close to world benchmarks and expand profitability. To sustain this regime, elimination of irregularities of blast furnace like hanging, channeling, and scaffolding is very essential. In this paper, sustaining of zero hanging spell for consecutive three years with low coke rate operation by improvement in burden characteristics, burden distribution, changes in slag regime, casting practices and adequate automation of the furnace operation has been illustrated. Models have been created to comprehend and upgrade the blast furnace process understanding. A model has been developed to predict the process of maintaining slag viscosity in desired range to attain proper burden permeability. A channeling prediction model has also been developed to understand channeling symptoms so that early actions can be initiated. The models have helped to a great extent in standardizing the control decisions of operators at H-Blast Furnace of Tata Steel, Jamshedpur and thus achieving process stability for last three years. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hanging" title="hanging">hanging</a>, <a href="https://publications.waset.org/abstracts/search?q=channelling" title=" channelling"> channelling</a>, <a href="https://publications.waset.org/abstracts/search?q=blast%20furnace" title=" blast furnace"> blast furnace</a>, <a href="https://publications.waset.org/abstracts/search?q=coke" title=" coke"> coke</a> </p> <a href="https://publications.waset.org/abstracts/74931/achieving-process-stability-through-automation-and-process-optimization-at-h-blast-furnace-tata-steel-jamshedpur" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/74931.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">195</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3408</span> Pattern of External Injuries Sustained during Bomb Blast Attacks in Karachi, Pakistan from 2000 to 2007</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arif%20Anwar%20Surani">Arif Anwar Surani</a>, <a href="https://publications.waset.org/abstracts/search?q=Salman%20Ali"> Salman Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=Asif%20Surani"> Asif Surani</a>, <a href="https://publications.waset.org/abstracts/search?q=Sohaib%20Zahid"> Sohaib Zahid</a>, <a href="https://publications.waset.org/abstracts/search?q=Akbar%20Shoukat%20Ali"> Akbar Shoukat Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=Zeeshan-Ul-Hassan%20Usmani"> Zeeshan-Ul-Hassan Usmani</a>, <a href="https://publications.waset.org/abstracts/search?q=Joseph%20Varon"> Joseph Varon</a>, <a href="https://publications.waset.org/abstracts/search?q=Salim%20Surani"> Salim Surani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objective: Terrorism and suicidal bomb blast attacks are commonplace in Karachi, Pakistan. During the years 2000 to 2007, there were over 60 bomb explosions resulting in more than 1500 casualties. These explosions produce a wide variety of external injuries. We undertook this study to evaluate pattern of external injury produced after bomb blast attacks and to compare injury profile resulting from explosions in open versus semi-confined blast environments. Method: A retrospective, cross-sectional, study was conducted to review injuries sustained after bomb blast attacks in Karachi, Pakistan, from January 2000 to October 2007. Emergency medical records and medico legal certificates of patients presented to three major public sector hospitals of Karachi were evaluated using self-design proforma. Results: Data of 481 victims meet inclusion criteria and were incorporated for final analysis. Of these, 63.6% were injured in open spaces and 36.4% were injured in semi-confined blast environments. Lacerations were commonly encountered as external injury (47.7%) followed by penetrating wounds (15.3%). Lower and upper extremities were most commonly affected (38.6% and 19% respectively). Open and semi-confined blast environments produced a specific injury pattern and profile (p=<0.001). Conclusions: Bomb blast attacks in Karachi produce an external injury pattern consistent with other studies, with exception of an increased frequency in penetrating wounds. Semi-confined blast environments were associated with severe injuries. Further studies are required to better classify injuries and their severity based on standardized scoring systems. Effective emergency response systems must be designed to cope with mass causalities following bomb explosions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bomb%20blast%20attacks" title="bomb blast attacks">bomb blast attacks</a>, <a href="https://publications.waset.org/abstracts/search?q=injury%20pattern" title=" injury pattern"> injury pattern</a>, <a href="https://publications.waset.org/abstracts/search?q=external%20injury" title=" external injury"> external injury</a>, <a href="https://publications.waset.org/abstracts/search?q=open%20space" title=" open space"> open space</a>, <a href="https://publications.waset.org/abstracts/search?q=semi-confined%20space" title=" semi-confined space"> semi-confined space</a>, <a href="https://publications.waset.org/abstracts/search?q=blast%20environment" title=" blast environment "> blast environment </a> </p> <a href="https://publications.waset.org/abstracts/27012/pattern-of-external-injuries-sustained-during-bomb-blast-attacks-in-karachi-pakistan-from-2000-to-2007" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27012.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">397</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3407</span> Heat Loss Control in Stave Cooled Blast Furnace by Optimizing Gas Flow Pattern through Burden Distribution</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Basant%20Kumar%20Singh">Basant Kumar Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=S.%20Subhachandhar"> S.

'I' Blast Furnace is the latest and largest Blast Furnace of Tata Steel Jamshedpur with working volume of 3230 m³ and with rated capacity of 3.055 million tons per annum. Optimizing heat losses in Belly and Bosh zone remained major challenge for blast furnace operators after its commissioning. 'I' Blast has installed Cast Iron & Copper Staves cooling members where copper staves are installed in Belly, Bosh & Lower Stack whereas cast iron staves are installed in upper stack area. Stave cooled Blast Furnaces are prone to higher heat losses in Belly and Bosh region with an increase in coal injection rate as Bosh gas volume increases. Under these conditions, managing gas flow pattern through proper burden distribution, casting techniques & by maintaining desired raw material qualities are of utmost importance for sustaining high injection rates. This study details, the burden distribution control by Ore & Coke ratio adjustment at wall and center of Blast Furnace as the coal injection rates increased from 140 kg/thm to 210 kg/thm. Control of blowing parameters, casting philosophy, specification for raw materials & devising operational practice for controlling heat losses is also elaborated with the model that is used to visualize heat loss pattern in different zones of Blast Furnace. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=blast%20furnace" title="blast furnace">blast furnace</a>, <a href="https://publications.waset.org/abstracts/search?q=staves" title=" staves"> staves</a>, <a href="https://publications.waset.org/abstracts/search?q=gas%20flow%20pattern" title=" gas flow pattern"> gas flow pattern</a>, <a href="https://publications.waset.org/abstracts/search?q=belly%2Fbosh%20heat%20losses" title=" belly/bosh heat losses"> belly/bosh heat losses</a>, <a href="https://publications.waset.org/abstracts/search?q=ore%2Fcoke%20ratio" title=" ore/coke ratio"> ore/coke ratio</a>, <a href="https://publications.waset.org/abstracts/search?q=blowing%20parameters" title=" blowing parameters"> blowing parameters</a>, <a href="https://publications.waset.org/abstracts/search?q=casting" title=" casting"> casting</a>, <a href="https://publications.waset.org/abstracts/search?q=operation%20practice" title=" operation practice"> operation practice</a> </p> <a href="https://publications.waset.org/abstracts/74757/heat-loss-control-in-stave-cooled-blast-furnace-by-optimizing-gas-flow-pattern-through-burden-distribution" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/74757.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">375</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3406</span> Development of Blast Vibration Equation Considering the Polymorphic Characteristics of Basaltic Ground</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dong%20Wook%20Lee">Dong Wook Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Seung%20Hyun%20Kim"> Seung Hyun Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Geological structure formed by volcanic activities shows polymorphic characteristics due to repeated cooling and hardening of lava. The Jeju region is showing polymorphic characteristics in which clinker layers are irregularly distributed along with vesicular basalt due to volcanic activities. Accordingly, resident damages and environmental disputes occur frequently in the Jeju region due to blasting. The purpose of this study is to develop a blast vibration equation considering the polymorphic characteristics of basaltic ground in Jeju. The blast vibration equation consists of a functional formula of the blasting vibration constant K that changes according to ground characteristics, and attenuation index n. The case study results in Jeju showed that if there are clinker layers, attenuation index n showed a distribution of -1.11~-1.87, whereas if there are no clinker layers, n was -2.79. Moreover, if there are no clinker layers, the frequency of blast vibration showed a high frequency band from 30Hz to 100Hz, while in rocks with clinker layers it showed a low frequency band from 10Hz to 20Hz. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=blast%20vibration%20equation" title="blast vibration equation">blast vibration
