Engineering construction in this era is facing challenge of shortage of fresh water for mixing and curing. Since potable water has become a scarce in the planet, replacing seawater for fresh water in the construction of both Reinforced Cement Concrete (RCC) and Plain Cement Concrete (PCC) structure should be welcomed. But the major consequences faced by the concrete structure due to the use of seawater was corrosion and variation of strength characteristic. This project deals with the addition of a bacteria named Bacillus subtilis JC3 in the concrete mix, which is made up of seawater. This can reduce the adverse effects of seawater in the concrete structure. The Bacillus subtilis JC3 bacteria is usually used in waste management. The bacterial culture is added to the concrete with seawater. It shows self-healing mechanism when cracks are formed. It is due to the calcite precipitation by the bacteria. The bacterial concrete is shows better strength and durability than ordinary concrete mix. These bacteria can survive in adverse situations also.
