Investigation on Bacterial Cement Composites

Abstract

Concrete are the most important materials used in construction industries where the external forces more than the design loads mainly the lateral forces which leads to the deformation and produce cracks in the joints of the structural member. The usage of cement has been increased more over the world results in the air pollution which leads to the ozone depletion .To overcome these type of problem like crack formation and usage of cement content used for repair works can be reduced by using the self healing bacterial concrete. These are materials which heals the crack automatically when the cracks are formed. These self healing is achieved by means of using the Biological healing aspect by using the bacterial concrete. Bacteria are used during the mixing of concrete will cure the cracks the automatically by means of it screeds known as calcium carbonate precipitate. In these study horizontal forces are applied to the three storey single bay framed structure by means of using the hydraulic jack in which the cracks are formed in the framed structure mainly the cracks are formed in the Beam-Column Joints. The Cracks leads to the penetration of oxygen inside the reinforcement area will forms the Corrosion. To avoid the formation of corrosion the cracks bacterial concrete along with 60% of fly ash are used which results in self healing process. These self healing which cure and arrest the cracks in the structure which gives the environment free pollution and sustainable structure.
