High Performance Concrete (HPC) appears to be a better choice for a strong and durable structure. Suitable addition of mineral admixtures such as silica fume, ground granulated blast furnace slag, rice husk ash, fly ash and highly reactive metakaolin in concrete or induction of suitable bacteria in concrete improve the strength and durability of concrete due to considerable improvement in the microstructure of concrete composites. One effective remedy for closure of cracks is the Bacterial Concrete (BC) which will continuously deposit calcite in concrete. This, phenomenon is called as Microbiologically Induced Calcite Precipitation (MICP). The urease enzyme enables the deposition of calcium carbonate (CaCO3) with the help of bacteria. The bacterial remediation technique surpasses other techniques as it is bio-based, eco-friendly and durable. Bacteria need to offer resistance to withstand high pH of concrete and mechanical stresses during mixing.
