- The building with crack has all the power to spoil the strength and aesthetic view and it may also lead to collapse. Crack lets in the moisture and hence the permeability increases in concrete which results in corrosion of reinforcement. As a result the tensile strength and compressive strength of the building will get reduced considerably. In this research, steel slag is used as a replacement material for fine and coarse aggregate, after comparing the properties of steel slag with the standard conventional material from 0 to 50% in steps of 10%. By inculcating bacteria in the optimum replaced steel slag concrete, in various quantities of 10ml, 20ml and 30ml, UPV (ultrasonic pulse velocity) test is conducted after 28 days of curing. The bacterium used is Bacillus subtilis, which is a gram positive cell bacterium. The increase in compressive, tensile and flexural strength of SSBC (Steel Slag Bacterial Concrete) is observed than the CC (conventional concrete) of M20 grade. No flaws are deducted in SSBC. The performance characteristics of steel slag concrete can be improved by Bacillus subtilis bacterium which can be easily cultured and safely used and moreover self healing of cracks can be made.
