The results were obtained for compressive strength, split tensile strength and flexural strength at7days, 28days, 56days and 90days.It was found that the addition of microsilica increases the compressive strength at all levels in comparison to standard mix whereas the strength decreases after attaining a certain percentage. The similar results were also obtained in case of nanosilica but the strength is much higher at the initial ages due to the reaction of unhydrated calcium hydroxide with nanosilica. After certain percentage, the compressive strength decreases with further increases in nanosilica.","author":[{"@context":"https://schema.org","@type":"Person","name":"International Journal of Recent

The physical and chemical properties of these materials were first analyzed, then the properties of neat samples, mortar samples, and concrete samples were investigated. Mainly this study focused on the workability and compressive strength with different mixes at different ages of neat, mortar and concrete mixes. Test results obtained in this study indicate that up to 5% nanosilica and 10% of microsilica could be advantageously blended with cement without adversely affecting the strength. However, optimum levels of these materials are 1-3% of nanosilica and 3-8% of microsilica when we consider the strength of concrete.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"Influence of Nanosilica and Microsilica on Properties of Concrete","attachmentId":88435941,"attachmentType":"pdf","work_url":"https://www.academia.edu/82881128/Influence_of_Nanosilica_and_Microsilica_on_Properties_of_Concrete","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/82881128/Influence_of_Nanosilica_and_Microsilica_on_Properties_of_Concrete"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="1" data-entity-id="110257903" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/110257903/Effect_of_nanosilica_on_the_mechanical_and_microstructural_properties_of_a_normal_strength_concrete_produced_in_Nigeria">Effect of nanosilica on the mechanical and microstructural properties of a normal strength concrete produced in Nigeria</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="4487331" href="https://abu.academia.edu/AmanaOcholi">Amana Ocholi</a></div><p class="ds-related-work--metadata ds2-5-body-xs">Nigerian Journal of Technology, 2020</p><p class="ds-related-work--abstract ds2-5-body-sm">The failure of conventional concrete to have classical mechanical properties, reduced permeability and lead to sustainability in concrete production called for the use of supplementary Cementitious Materials (SCM) in concrete to improve its performance.

The work involves using four types of mixes, the first one includes normal mix concrete containing 0% microsilica and 0% nanosilica, the second one includes replacing the cement with different percentages of microsilica (7%, 8%, 9%),the third one includes replacing the cement with different percentages of nanosilica (1%, 2%, 3%), and the fourth one includes replacing the cement with different percentages of mixture of microsilica (7%, 8%, 9%)and nanosilica (1%, 2%, 3%).For each percentage of mix preparation, six cube specimen and six beam specimen were casted and then cured for a period of 7 days and 28 days. The results obtained from the experimental work showed that the compressive strength as well as flexural strength of concrete is increased when cement is replaced with microsilica and nanosilica. Microsilica gave maximum compressive strength and flexural strength at 8% and nanosilica gave maximum compressive strength and flexural strength at 2%. Also, maximum compressive strength and flexural strength was achieved at 8% microsilica and 2% nanosilica when we are using the mixture of both.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"EFFECT OF MICRO-SILICA AND NANO-SILICA ON MECHANICAL PROPERTIES OF CONCRETE","attachmentId":57385697,"attachmentType":"pdf","work_url":"https://www.academia.edu/37420347/EFFECT_OF_MICRO_SILICA_AND_NANO_SILICA_ON_MECHANICAL_PROPERTIES_OF_CONCRETE","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/37420347/EFFECT_OF_MICRO_SILICA_AND_NANO_SILICA_ON_MECHANICAL_PROPERTIES_OF_CONCRETE"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="4" data-entity-id="105564659" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/105564659/Influence_of_nanosilica_on_mechanical_and_durability_properties_of_concrete">Influence of nanosilica on mechanical and durability properties of concrete</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="277410170" href="https://independent.academia.edu/kujurjitu">jitu kujur</a></div><p class="ds-related-work--metadata ds2-5-body-xs">Proceedings of the Institution of Civil Engineers - Structures and Buildings, 2018</p><p class="ds-related-work--abstract ds2-5-body-sm">The results of an experimental study on the effect of the partial replacement of ordinary Portland cement with nanosilica (NS) on the mechanical and durability properties of concrete are presented. Concrete mixes were made with varying NS contents at a constant water/binder ratio of 0·40. The test results demonstrated that the inclusion of 3% NS as a partial replacement of cement enhanced the mechanical properties and reduced the water penetration depth and water absorption of the concrete, resulting in overall improved performance. Compared with normal concrete, the water penetration depth and water absorption of the NS concrete was reduced by 42·85% and 36·84%, respectively. The carbonation depth was also reduced as a result of cement replacement with NS, leading to enhanced concrete durability. These enhancements in the mechanical and durability properties were mainly due to the high fineness and increased pozzolanic activity of the added NS.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"Influence of nanosilica on mechanical and durability properties of concrete","attachmentId":104983232,"attachmentType":"pdf","work_url":"https://www.academia.edu/105564659/Influence_of_nanosilica_on_mechanical_and_durability_properties_of_concrete","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/105564659/Influence_of_nanosilica_on_mechanical_and_durability_properties_of_concrete"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="5" data-entity-id="43655471" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/43655471/Effects_of_the_nanosilica_addition_on_cement_concrete_A_review">Effects of the nanosilica addition on cement concrete: A review</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="88902681" href="https://amu-in.academia.edu/MoonisZaheer">Moonis Zaheer</a><span>, </span><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="162855857" href="https://independent.academia.edu/GulzarHBarbhuiya">Gulzar H Barbhuiya</a><span>, </span><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="49978051" href="https://independent.academia.edu/SYEDHASAN69">SYED HASAN</a></div><p class="ds-related-work--metadata ds2-5-body-xs">Elsevier, 2019</p><p class="ds-related-work--abstract ds2-5-body-sm">Nanotechnology has given a new dimension to the concrete world. Among the nanomaterials used as partial replacement of cement, nanosilica (NS) has been used immensely. This review paper summarizes the preparation of nanosilica useable for concrete production, effects of nanosilica addition on cement concrete in terms of varied components, fresh state as well as hardened state and physical properties like workability, setting times, etc. The nanosilica addition hinders workability as the surface area occupied by the nanosilica is quite large. The setting time reduces to a great extent. It gives an in-depth review of nanosilica added concrete prepared using various other additives. The mechanical properties like com-pressive strength, split tensile strength, flexural strength, and elasticity modulus are discussed in details. Also, the durability aspects of the nanosilica added concrete, the microstructural characterization, and the reduction of structural micropores are discussed in detail. The addition of nanosilica increases the strength properties as well as the durability but reduces the structural micropores. Further, the present scenario and the recommendation for future works of nanosilica application on cement concrete are presented. The use of nanosilica can reduce the consumption of cement, which releases CO 2 , responsible for global warming. All these aspects make nanosilica added concrete an essential and sustainable material for construction purposes.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"Effects of the nanosilica addition on cement concrete: A review","attachmentId":63955917,"attachmentType":"pdf","work_url":"https://www.academia.edu/43655471/Effects_of_the_nanosilica_addition_on_cement_concrete_A_review","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/43655471/Effects_of_the_nanosilica_addition_on_cement_concrete_A_review"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="6" data-entity-id="30851689" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/30851689/Comparative_study_of_the_effects_of_microsilica_and_nanosilica_in_concrete">Comparative study of the effects of microsilica and nanosilica in concrete</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="48324397" href="https://independent.academia.edu/JGaitero">J.

These properties were improved using micro- and nano-sized pozzolanic mineral admixtures as stated by various authors. In this paper, author has emphasized mostly on using micro- and nanosilica materials with cement. Literature survey revealed that the most suited mineral admixtures for getting highest behaviors are micro- and nanosilica. Nanotechnology is nowadays a buzzword in everyone’s tips. Nanotechnology in concrete means the addition of nano-sized materials in the range of 1 and 100 nm to improve the behavior of cement and concrete. Micro- and nano-sized silica particles improve the porous behavior of concrete and also produce more calcium silicate hydrate resulting from chemical reaction of nanoparticles and calcium hydroxide. On the other hand, it makes concrete more compact in microstructure point of view, which improves density, strength, and also durabil...</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"Individual and Combined Effect of Nano- and Microsilica on Cement-Based Product","attachmentId":77707960,"attachmentType":"pdf","work_url":"https://www.academia.edu/66566763/Individual_and_Combined_Effect_of_Nano_and_Microsilica_on_Cement_Based_Product","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/66566763/Individual_and_Combined_Effect_of_Nano_and_Microsilica_on_Cement_Based_Product"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="8" data-entity-id="54691353" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/54691353/Influence_of_Nanosilica_on_Mechanical_Properties_Sorptivity_and_Microstructure_of_Lightweight_Concrete">Influence of Nanosilica on Mechanical Properties, Sorptivity, and Microstructure of Lightweight Concrete</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="163540904" href="https://zut.academia.edu/TeresaRuci%C5%84ska">Teresa Rucińska</a></div><p class="ds-related-work--metadata ds2-5-body-xs">Materials</p><p class="ds-related-work--abstract ds2-5-body-sm">This study presents the results of an experimental investigation of the effects of nanosilica (NS) on the strength development, transport properties, thermal conductivity, air-void, and pore characteristics of lightweight aggregate concrete (LWAC), with an oven-dry density &lt;1000 kg/m3. Four types of concrete mixtures, containing 0 wt.%, 1 wt.%, 2 wt.%, and 4 wt.% of NS were prepared. The development of flexural and compressive strengths was determined for up to 90 days of curing. In addition, transport properties and microstructural properties were determined, with the use of RapidAir, mercury intrusion porosimetry (MIP), and scanning electron microscopy (SEM) techniques. The experimental results showed that NS has remarkable effects on the mechanical and transport properties of LWACs, even in small dosages. A significant improvement in strength and a reduction of transport properties, in specimens with an increased NS content, was observed.

Micro and nanosilica react with calcium hydroxide producing calcium silicate hydrates (C-S-H), thus the voids and pores within concrete are filled and new minerals are formed in the gaps between cement grains and aggregate particles. Unreacted round microsilica and nanosilica particles were registered using SEM in 28 days old samples and were not found in 6 month old sample. The compressive strength results indicate that concrete still continues to harden after the 28-days of curing.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"The Formation of Microstructure in High Strength Concrete Containing Micro and Nanosilica","attachmentId":40060857,"attachmentType":"pdf","work_url":"https://www.academia.edu/18432589/The_Formation_of_Microstructure_in_High_Strength_Concrete_Containing_Micro_and_Nanosilica","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/18432589/The_Formation_of_Microstructure_in_High_Strength_Concrete_Containing_Micro_and_Nanosilica"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div></div></div><div class="ds-sticky-ctas--wrapper js-loswp-sticky-ctas hidden"><div class="ds-sticky-ctas--grid-container"><div class="ds-sticky-ctas--container"><button class="ds2-5-button js-swp-download-button" data-signup-modal="{"location":"continue-reading-button--sticky-ctas","attachmentId":51367716,"attachmentType":"pdf","workUrl":null}">See full PDF</button><button class="ds2-5-button ds2-5-button--secondary js-swp-download-button" data-signup-modal="{"location":"download-pdf-button--sticky-ctas","attachmentId":51367716,"attachmentType":"pdf","workUrl":null}"><span class="material-symbols-outlined" style="font-size: 20px" translate="no">download</span>Download PDF</button></div></div></div><div class="ds-below-fold--grid-container"><div class="ds-work--container js-loswp-embedded-document"><div class="attachment_preview" data-attachment="Attachment_51367716" style="display: none"><div class="js-scribd-document-container"><div class="scribd--document-loading js-scribd-document-loader" style="display: block;"><img alt="Loading..." src="//a.academia-assets.com/images/loaders/paper-load.gif" /><p>Loading Preview</p></div></div><div style="text-align: center;"><div class="scribd--no-preview-alert js-preview-unavailable"><p>Sorry, preview is currently unavailable.
