An Experimental Investigation on the Bacterial Concrete as an Innovative Approach to Self Crack Healing System

Concrete structure are subjected to cracks and it is one of the immanent frailties of concrete thus reduces the life of concrete structure thereby results in high replacement cost. The study was inspired by the technique to find a remedy for cracking using bacteria namely Bacillus subtilis and Bacillus cereus on filling the voids, and the compressive strength, split tensile strength and flexural strength of bacterial impregnated concrete are compared with conventional concrete. The evaluated results of strength revealed that the use of bacteria in combination showed better improvement and SEM, XRD analysis showed that the material growth, increased calcite crystalline when compared to conventional concrete.
