Abstract: The bio-mineralisation method gives potential outcomes in the micro-structure of concrete by precipitating CaCO3 in concrete. Be that as it may, the micro-organisms need a supplement source for their better development in concrete. In this manner, calcium lactate is moreover included in the concrete as a supplement source for micro-organisms. It is imperative to know the impact of this calcium lactate and bacteria on the properties of concrete. In this study, an endeavour is made to know the impact of calcium lactate and Bacillus subtilis bacteria on properties of concrete. Results demonstrate that there is a decrement in the carbonation rate and improvement in the compressive strength. Scanning electron microscope analysis shows that the dense matrix is obtained in bacterial concrete as compared to the control mix. The significant findings of this examination affirm that the performance of concrete improved by adding calcium lactate and Bacillus subtilis bacteria into the concrete.
