This paper presents the results of an experimental investigation carried out to evaluate the influence of \u003cem\u003eSporosarcina pasteurii\u003c/em\u003e bacteria on the behaviour of two types of concretes (light weight aggregate concrete and normal weight concrete). The resistance of specimens to water penetration by testing water absorption and evaluating the electrical resistance of those concretes was examined and compared. As a conclusion, 20% increase in electrical resistance and 10% reduction in water absorption of lightweight aggregate concrete (LWAC) and for normal concrete the results show 7% decrease in water absorption and almost 10% increase in electrical resistance.\u003c/p\u003e", "languages": [{"id": "eng", "title": {"en": "English"}}], "publication_date": "2019-03-02", "publisher": "Zenodo", "resource_type": {"id": "publication-article", "title": {"de": "Zeitschriftenartikel", "en": "Journal article"}}, "rights": [{"description": {"en": "The Creative Commons Attribution license allows re-distribution and re-use of a licensed work on the condition that the creator is appropriately credited."}, "icon": "cc-by-icon", "id": "cc-by-4.0", "props": {"scheme": "spdx", "url": "https://creativecommons.org/licenses/by/4.0/legalcode"}, "title": {"en": "Creative Commons Attribution 4.0 International"}}], "title": "Influential Effect of Self-Healing Treatment on Water Absorption and Electrical Resistance of Normal and Light Weight Aggregate Concretes", "version": "10010219"}, "parent": {"access": {"owned_by": {"user": "32148"}, "settings": {"accept_conditions_text": null, "allow_guest_requests": false, "allow_user_requests": false, "secret_link_expiration": 0}}, "communities": {"default": "dcee738f-2469-4bea-a94c-c91d67acd598", "entries": [{"access": {"member_policy": "open", "members_visibility": "public", "record_submission_policy": "open", "review_policy": "open", "visibility": "public"}, "children": {"allow": false}, "created": "2018-01-30T06:09:25.661623+00:00", "custom_fields": {}, "deletion_status": {"is_deleted": false, "status": "P"}, "id": "dcee738f-2469-4bea-a94c-c91d67acd598", "links": {}, "metadata": {"curation_policy": "", "page": "\u003cp\u003eName of the publisher \u0026nbsp;: Science Press\u003cbr /\u003e\r\nStatus of Publication \u0026nbsp;: Current serial (c) Start date of publication or projected start date for pre-publications : 2007-01\u003cbr /\u003e\r\nFrequency: Monthly (m)\u003cbr /\u003e\r\nLanguage \u0026nbsp;: English (eng)\u003cbr /\u003e\r\nMedium \u0026nbsp;: Print (ta)\u003cbr /\u003e\r\nISSN 2415-1734\u003c/p\u003e", "title": "International Journal of Architectural, Civil and Construction Sciences"}, "revision_id": 0, "slug": "ijaccs", "updated": "2018-01-30T06:10:26.665034+00:00"}], "ids": ["dcee738f-2469-4bea-a94c-c91d67acd598"]}, "id": "2643851", "pids": {"doi": {"client": "datacite", "identifier": "10.5281/zenodo.2643851", "provider": "datacite"}}}, "pids": {"doi": {"client": "datacite", "identifier": "10.5281/zenodo.2643852", "provider": "datacite"}, "oai": {"identifier": "oai:zenodo.org:2643852", "provider": "oai"}}, "revision_id": 9, "stats": {"all_versions": {"data_volume": 13361590.0, "downloads": 55, "unique_downloads": 53, "unique_views": 84, "views": 88}, "this_version": {"data_volume": 13361590.0, "downloads": 55, "unique_downloads": 53, "unique_views": 84, "views": 88}}, "status": "published", "ui": {"access_status": {"description_l10n": "The record and files are publicly accessible.", "embargo_date_l10n": null, "icon": "unlock", "id": "open", "message_class": "", "title_l10n": "Open"}, "created_date_l10n_long": "April 17, 2019", "creators": {"affiliations": [], "creators": [{"person_or_org": {"family_name": "B.

This paper presents the results of an experimental investigation carried out to evaluate the influence of \u003cem\u003eSporosarcina pasteurii\u003c/em\u003e bacteria on the behaviour of two types of concretes (light weight aggregate concrete and normal weight concrete). The resistance of specimens to water penetration by testing water absorption and evaluating the electrical resistance of those concretes was examined and compared. As a conclusion, 20% increase in electrical resistance and 10% reduction in water absorption of lightweight aggregate concrete (LWAC) and for normal concrete the results show 7% decrease in water absorption and almost 10% increase in electrical resistance.\u003c/p\u003e", "languages": [{"id": "eng", "title": {"en": "English"}}], "publication_date": "2019-03-02", "publisher": "Zenodo", "resource_type": {"id": "publication-article", "title": {"de": "Zeitschriftenartikel", "en": "Journal article"}}, "rights": [{"description": {"en": "The Creative Commons Attribution license allows re-distribution and re-use of a licensed work on the condition that the creator is appropriately credited."}, "icon": "cc-by-icon", "id": "cc-by-4.0", "props": {"scheme": "spdx", "url": "https://creativecommons.org/licenses/by/4.0/legalcode"}, "title": {"en": "Creative Commons Attribution 4.0 International"}}], "title": "Influential Effect of Self-Healing Treatment on Water Absorption and Electrical Resistance of Normal and Light Weight Aggregate Concretes", "version": "10010219"}, "parent": {"access": {"owned_by": {"user": "32148"}, "settings": {"accept_conditions_text": null, "allow_guest_requests": false, "allow_user_requests": false, "secret_link_expiration": 0}}, "communities": {"default": "dcee738f-2469-4bea-a94c-c91d67acd598", "entries": [{"access": {"member_policy": "open", "members_visibility": "public", "record_submission_policy": "open", "review_policy": "open", "visibility": "public"}, "children": {"allow": false}, "created": "2018-01-30T06:09:25.661623+00:00", "custom_fields": {}, "deletion_status": {"is_deleted": false, "status": "P"}, "id": "dcee738f-2469-4bea-a94c-c91d67acd598", "links": {}, "metadata": {"curation_policy": "", "page": "\u003cp\u003eName of the publisher \u0026nbsp;: Science Press\u003cbr /\u003e\r\nStatus of Publication \u0026nbsp;: Current serial (c) Start date of publication or projected start date for pre-publications : 2007-01\u003cbr /\u003e\r\nFrequency: Monthly (m)\u003cbr /\u003e\r\nLanguage \u0026nbsp;: English (eng)\u003cbr /\u003e\r\nMedium \u0026nbsp;: Print (ta)\u003cbr /\u003e\r\nISSN 2415-1734\u003c/p\u003e", "title": "International Journal of Architectural, Civil and Construction Sciences"}, "revision_id": 0, "slug": "ijaccs", "updated": "2018-01-30T06:10:26.665034+00:00"}], "ids": ["dcee738f-2469-4bea-a94c-c91d67acd598"]}, "id": "2643851", "pids": {"doi": {"client": "datacite", "identifier": "10.5281/zenodo.2643851", "provider": "datacite"}}}, "pids": {"doi": {"client": "datacite", "identifier": "10.5281/zenodo.2643852", "provider": "datacite"}, "oai": {"identifier": "oai:zenodo.org:2643852", "provider": "oai"}}, "revision_id": 9, "stats": {"all_versions": {"data_volume": 13361590.0, "downloads": 55, "unique_downloads": 53, "unique_views": 84, "views": 88}, "this_version": {"data_volume": 13361590.0, "downloads": 55, "unique_downloads": 53, "unique_views": 84, "views": 88}}, "status": "published", "ui": {"access_status": {"description_l10n": "The record and files are publicly accessible.", "embargo_date_l10n": null, "icon": "unlock", "id": "open", "message_class": "", "title_l10n": "Open"}, "created_date_l10n_long": "April 17, 2019", "creators": {"affiliations": [], "creators": [{"person_or_org": {"family_name": "B.
