Abstract:
Now-a-days alternative approaches in construction technology are evolving rapidly in a bid to curtail the environmental hazards and low sustainability imparted by the prevalent technologies. Our study deals with the feasibility of application of a novel bacterial protein Bioremediase, on the most widely used cementitious material worldwide- Portland Pozzolana Cement, hitherto found to increase the compressive strength, flexural strength on Ordinary Portland cement based concrete and mortar samples. This silica leaching protein in its purified lyophilized form when impregnated into the Portland Pozzolana Cement based concrete and mortar samples, found to increase remarkably the compressive strength, flexural strength, resistance to commonplace environmental pollutants (water absorption and sulphate ion) as well as self-healing attributes of the test specimens. This Bioremediase protein exhibits sustainability across a wide time and temperature barrier. These findings along with the fact that this protein does not impart any negative repercussion on human health may render it as a prospective agent in construction technology.
