Concrete is most used material in construction, and cracks are formed in concrete structures due to uneven settlements and climatic conditions of atmosphere due to variation of co-efficient of linear expansion valve of concrete. Hear has introduced in the bacteria in concrete itself healing and reduce the cracks in structures and improve the strength and durability for long time using the Bacillus Flexus in concrete to heal the cracks. The healing of concrete is process with in duration after that Analyse the regain strength for motor cubes, cubes and cylinder after 28 days, 45 days and 60 days of cracking of concrete specimens. Behaviour of concrete analysis done and ultrasonic pulse velocity test are carried.SEM Analysis is to find the calcite crystals formation in the concrete. It shows that above 80 percent strength gained from initial valve was observed. The first intensive report and novel methodology of crack healing ability of native isolate of Bacillus flexus and compressive strength is 105cells/ml.
