Description
Summary:Whatever legacy the building may have cracks have all powers to spoil both their aesthetic view and strength. Structural cracks cause’s damages to buildings, Monuments etc., and it may also lead to collapsing of the structure. A crack let in moisture and increases the permeability of the concrete which results in corrosion of reinforcement. As a result the tensile strength and compressive strength of the building is reduced considerably causing collapse of buildings. By using bacterial concrete, the cracks can be avoided. The bacteria to be used in our project are Bacillus Subtilis which is a gram positive cell bacterium. The bacteria increase the compressive and tensile strength of RC elements in building for the similar grade of conventional concrete. Thus it doesn’t allow cracks to occur. The bacteria remain active for 200 years. It is also harmless to human and eco-friendly. The bacteria absorb the moisture in the building and increase its growth and reproduction. Even if any cracks occur, the bacteria self-heals the crack.
