Abstract

Owing to the load bearing and the other external environmental factors, the defects in the concrete occur in the form of cracks and flaws which leads to the reduction in the durability characteristics. Generally, the bacteria-based autogenous healing is adopted to restore those cracks. The ureolytic bacteria used urea as a source of nitrogen and convert it to carbonate ions, and then carbonate ions react with calcium ions to induce calcium carbonate in the presence of water. In the present study, binary cement-based concrete containing different concentration of immobilized bacteria is investigated, and its performance is evaluated based on the strength and durability characteristics. The experimentation includes bagasse ash (
