Abstract

This study investigates the effect of deploying Bio cement on mechanical properties of hardened concrete of Grade M25. Percolation of crack can lead to leakage problems causing concrete matrix deterioration or corrosion of embedded steel reinforcement. As bacterial concrete mainly focuses on self-healing property, with the study of closing (or) controlling cracks at the origin itself is the concept of bio-cement. Bacteria and an organic precursor are the agent. Bio cement has used as volume substitution by 0.5%, 1%, 1.5% and 2% by the weight of the cement. A notable improvement is being noticed in the strength properties of concrete when bio cement is used. Bacteria consume oxygen internally to prevent corrosion of reinforced concrete. The bacteria, however, pose no risk to human health, since they can only survive under alkaline conditions in concrete. The addition of bio cement to the concrete not only reduces permeability but will improve the properties of strength as well as durability to a great extent.

Keywords: bio-cement; MICCP; C-S-H gel; strength; durability
