The present investigation is to obtain the performance of the concrete by microbiologically induced special growth. One such has led to the development of a very special concrete known as bacterial concrete where bacteria is induced in the mortars and concrete to heal up the faults. Researchers with different bacteria proposed different concretes .here an attempt was made by using the bacteria “bacillus subtilis”. This study showed a significant increase in the compressive strength due to the addition of bacteria. The chemical traces copper , sulphate and alumina present in the slag are not harmful many researchers had already found ,copper slag possible to use as a material in concrete In this experiment study copper slag in concrete as replacement material of fine aggregate. When 60ml, 180ml of bacillus subtilis and 20%, 40% of copper slag is added in M20 grade concrete it attains maximum compressive strength on adding 180ml. In concrete self –healing property is successfully achieved due to addition of bacteria.
