MICROBIAL CONCRETE: THE PIONEERING WORK ON REPAIRING CONCRETEAbstract
The global demand of concrete is increasing every year and generally is considered as most consumed material on earth. But concrete is vulnerable to deterioration, corrosion, and cracks, and the consequent damage and loss of strength requires immensely expensive remediation and repair. One such mechanism that receives increasing attention in recent years is the ability for self-repair. So a novel and inexpensive method is available for overcoming the mentioned problem. The microbial concrete makes use of calcite precipitation by bacteria. A specific group of alkali-resistant spore-forming bacteria related to the genus Bacillus was selected for this purpose, the phenomenon is called microbiologically induced calcite precipitation (MICP). Bacillus Pasteruii, a common soil bacterium, can induce the precipitation of calcite. Due to its inherent ability to precipitate calcite continuously, bacterial concrete can be called as a “Smart Bio Material” for repairing concrete.
