Abstract

One of the most popular and indispensable building materials is concrete. It often develops microscopic fissures that could eventually grow larger. Members start to deteriorate as a result of this. By including specific components, self-healing concrete can be utilised to repair cracks on its own. The two forms of self-healing concrete used in this study. Those prepared with cystalline admixture and those made with Bacillus subtilis bacteria. Properties of the two concrete are compared, and their potential for healing is assessed. 1% ,2% and 3% of crystalline admixture are added to the specimens whereas 5% , 10% and 20% crystalline admixtures are added to the specimen. Cracks are induced into each percentage for the analysis of healing of the casted concrete specimens.
