This study is about the potential for bacteria to fill the micro pores in the concrete the experimental investigation was to find the ability of the concrete with and without bacteria. The micro pores are filled by calcite precipitation created by the bacteria that will create autogenous healing to the concrete. The bacillus family bacteria was create the alkali-resistant spore this formation make as self-healing of the concrete. The active viable period of the bacteria was 4 months in water before adding to the concrete. The continuous decrease of the spore size diameter in concrete its helps to increase the compressive strength of the concrete. The life span and the concrete that is the durability of the concrete was increased we have a sustainable concrete. The present investigation is aimed to answer the following queries: Growth and culture of bacteria, effect of different cell concentration of bacteria embedded on the strength and durability characteristics of concrete.
