Abstract: This study focuses to develop the self-healing property of Engineered Cementitious Composites (ECC) with Polypropylene (PP) and Poly Vinyl Alcohol (PVA) fibres with Bacteria. Self-healing property of ECC based on Calcium Acetate precipitation induced through bacterial activity has been investigated in this project. This technique is highly desirable because the mineral precipitation induced, result and discussion are natural and pollution free. ECC specimen containing Bacillus subtilis were pre-cracked at 7 days. The conclusion on the mechanical properties and durability properties of ECC due to the mixing of bacteria is also discussed. Scanning electron microscope (SEM) is used to document the role of bacteria in microbiologically made mineral precipitation. The Bacterial ECC increase in mechanical and durability properties than the normal ECC, it also gives more workability when it is replaced with 10%, 20% and 30% of bacteria in water content with polypropylene fibre and polyvinyl alcohol fibre. It shows that PVA fibres give better performance compared to PP fibres and self-healing takes place under different exposures of the ECC specimens.
