Abstract: This paper presents the effect of Bacillus subtilis on the durabilityof fly ash enriched with bacteria. Cement is replaced with fly ash enriched with bacteria in three different proportions (25%,30%, and 35%).Tests performed after curing specimens for 28 days. Test results indicate fly ash enriched with bacteria has enhanced the durability of concrete. Maximum increase in strength and resistant to chloride ingress and water absorption was negligible was observed at 25% fly ash enriched with bacteria. This improvement in durability of concrete is due to deposition of bacteria on cell surface within pores. The present work shows the impact of Bascillus subtilis on durability of concrete made by partially replacing cement with fly ash. Usage of fly ash enriched with bacteria not only increases strength durability but also helps to achieve early day strength.
