Abstract

Concrete has been widely used for many years as a composite material for various types of structures. One of the weaknesses of concrete is that it cannot withstand tension which can cause cracks easily. Significant importance is given to study the cause of cracking in concrete and preventing them from propagating further. These efforts are important for timely repair, safety and long-term durability of critical concrete structures. This paper presents experimental investigation carried out to evaluate durability parameters for Bacterial concrete. For investigation, concrete cubes and beams with and without addition of Bacillus subtilis JC3 bacterium were cast and observations are made for the durability studies. It has been observed that there is a increased reduction in weight and strength when the cubes are exposed to 5% concentrated H2SO4,  in conventional concrete when compared to bacterial concrete. Further Bacterial concrete is more resistant in terms of Acid Durability Factor and Acid Attack Factor. An accelerated corrosion study on bacterial concrete is more sustainable than conventional concrete.
