The concrete is widely used construction material in the world. It has very good compressive strength but it is weakin tension. A typical durability-related phenomenon in many concrete constructions is crack formation. While larger crackshamper structural integrity, also smaller sub-millimeter sized cracks may result in durability problems as particularlyconnected cracks increase matrix permeability. Ingress water and chemicals can cause premature matrix degradation andcorrosion of embedded steel reinforcement. A novel strategy to restore or remediate such structures is bio mineralization ofcalcium carbonate using microbes. There are millions of bacteria available, and certain of it can be used in the constructionindustry for enhancement of the overall construction. Recently it is found that microbial mineral precipitation resulting frommetabolic activities of favorable microorganisms in concrete improved the overall behavior of concrete. The Application ofSpecific Calcite Mineral Precipitating Bactria for Concrete Repair & Plugging Of voids And Cracks In Concrete Has BeenRecently Investigated. The Possibilities Of Using Specific Bacillus Bacteria As Sustainable And Concrete EmbeddedSelf-healing Agent Was Studied & Results From Current Studies Are Discussed.The present study investigated the effects of Bacillus Subtilis Jc3 on compressive strength and water-absorption tests. Theresults showed a 16% increase in compressive strength of cement concrete with the addition of bacterial cells. Treated cubesabsorbed three times less water than control cubes as a result of microbial calcite deposition. Different proportions105,106,107,108and 109cells/ml concentration can be added but by studying of research paper we adopt optimumconcentration 107cells/ml in concrete to check the compressive strength and water-absorption tests
