Experimental Survey on Self-Sensing Concrete


  • Dr. Varinder, Dr. Ashwani Sethi


Traditional concrete is strong in compression but not so much in tension. When exposed to external conditions, typical concrete is readily broken. Self-healing microorganisms are put to the concrete to undertake biological restoration. Bacillus Subtilis, a self-healing microbe, was employed in this study. They are calcite-forming bacteria that produce precipitates in fractures when they come into contact with water. To make the structure more cost-effective, waste materials are also utilised in this project. Concrete is made by replacing cement with fly ash and sand with brick powder. The materials employed in this study are M30 concrete and Fe415 steel. In this study, 0 percent, 15%, and 30% replacement materials will be used, as well as the inclusion of self-healing bacteria as an admixture. The examples of these varied proportions will be cast, and the outcomes will be compared to standard concrete. The goal of this study is to develop a crack-resistant concrete that is also cost-effective. The usage of waste material reduces both the cost and the amount of garbage produced. The use of self-healing microorganisms in this study results in physiologically crack-proof concrete.
