Effect of Alccofine on Engineering and Durability Properties of Bacterial Concrete

Abstract

Concrete is cheap and easily available construction material in the world. So advancement in the concrete is to improve its compressive strength and durability of structures by using micro organisms carrying process of MICP.  This project discusses the filling of voids in fresh concrete and plugging of artificially cracked cement mortar using Bacillus Sphaericus and Proteus Vulgarious bacteria combined with sand as a filling material in artificially made cuts in cement mortar which was cured in urea and CaCl2 medium. The effect on the compressive strength, flexural strength due to the mixing of bacteria along with effect of water absorption and sorptivity on concrete cubes is also discussed in this project. The main aim of the project is to evaluate the strength in comparison with conventional and bio concrete cubes. The evaluated results suggest that there is significant increase in the strength of concrete.
