|Bacillus sphericus, Compressive strength, Concrete, Crack|
Concrete is the most widely used construction material for infrastructure but most concrete structures are prone to cracking. Tiny cracks on the surface of the concrete make the whole structure vulnerable because water seeps in to degrade the concrete and corrode the steel reinforcement greatly reducing the lifespan of a structure. As current crack filling material in concrete proved harmful and toxic. It can be replaced by recent innovative, eco-friendly material – Bacteria. Huge diverse bacterial species can participate in precipitation of mineral carbonate, even in many diverse conditions. Lots of work has been done for Bacillus Sphericus. So through this project we want to show the role of Bacillus Sphericus as crack- healing material in concrete to improve mechanical performance & its effect on various parameters of concrete.
