In today’s construction world, it is unrealistic to expect crack-free concrete structures. It is common for cracks to form in concrete structures, which allows water and other external medium to pass through and decrease the strength and durability of concrete. Concrete manufacturing also generates significant amounts of CO2, as does the chemical process of making cement itself. Every metric ton of cement produced generates roughly 1268 pounds of carbon dioxide. As a one-stop solution for the above issues, the bio concrete plays a vital role by autonomous self-healing mechanism. It offers benefits such as better performance than conventional concrete when bacteria, minerals, and polymers are mixed to produce an autonomous healing process in concrete. A number of experimental studies have shown that it improves concrete’s compressive strength, tensile strength, and water permeability. A study of the effect of Bacillus cereus on the strength of M25 concrete is presented in this paper. Bio concrete specimens performed far better than control specimens at 7 and 28 days of curing, as compared to control specimens.
