STUDY ON STRENGTH OF BACTERIAL CONCRETE IN BACILLUS MEGATERIUM

Concrete a strong, durable material composed of cement, aggregate and water is the most used building material in the world. Concrete has an ultimate load bearing capacity under compression but the material is weak in tension. The steel reinforced bars take the load when the concrete cracks in tension. To increase the strength and durability of the structure either crack that are formed should be repaired conventionally using epoxy injection or latex treatment or by providing extra reinforcement in the structure during the design phase to ensure that the crack width stays within a permissible limit. A reliable self-healing biological app of water approach is first proposed by V.Ramakrishnan to make use of bacterial concrete to heal cracks in concrete structure. In this paper an attempt is made to investigate the compressive strength and split tensile strength of the bio concrete. In this study different mix proportions for M30 grade of concrete with adding bacteria (Bacillus Megaterium) of 5g in 1lit/m3 of water.
