Abstract:

Concrete is a widely used material in construction that can with stand the compressive load. Because of its brittle nature, it is susceptible to cracks. These minor cracks in the structure lead to the ingress of fluids or substances into the concrete's lower layer. To avoid and overcome these cracks, need for an increase in the strength and durability of concrete. The introduction of bacteria into the concrete mixture works by precipitation of calcium carbonate to fill up the concrete cracks. In this research, extensive laboratory investigations have been carried out to study the effect of introducing Bacillus Subtilis Bacteria on concrete's mechanical properties. In addition to this Fire resisting properties of bacteria-induced concrete are studied. For the study, the microstructure of concrete SEM analysis is carried out on all mixes
In this paper, Bacterial Induced Concrete and plain concrete's experimental results are discussed for M40 Grade of concrete for two types of cement. The results show that bacterial induced concrete for OPC mix is 18% increase in compressive strength, 13.84 % increase in flexural strength and 11.32% increase in Split tensile strength compared with normal concrete.
