Concrete is one of the prime important material in construction industry. Improvements to the concrete is essential in order to increase the performance and sustainability. Good quality concrete mixes require adequate compaction during casting by skilled labors, which have some disadvantages. Self-compacting concrete (SCC) has the ability to self-level, and compact under its own weight without internal or external compaction. The major drawback of SCC is its low tensile strength which makes it susceptible to progression in micro-cracks resulting in low strength and durability. Steel fiber reinforced self-compacting concrete (SFRSCC) is an advancement to normal SCC. Steel fiber bridges the gap between the cracks, thus minimizing propagation of cracks. The calcite precipitating bacteria are introduced into the concrete during casting and when the cracks occurs in the presence of moisture, bacteria precipitates and heal the cracks.
