Improvement of Engineering Properties of Different Materials Using Microbial Treatment- A Review

Abstract

The method known as Microbially Induced Calcium Carbonate Precipitation, or MICP, has become a game-changer in the building materials industry. This review paper conducts a thorough analysis of current advancements and research results about the application of MICP to improve the characteristics of brick, concrete, and soil. Research has indicated that MICP can effectively increase durability, decrease permeability, and improve compressive strength in concrete through the creation of calcium carbonate crystals inside the concrete matrix. It can also activate self-healing properties through calcium carbonate precipitation. In the context of soil stabilization, MICP has proven to be a sustainable and environmentally friendly solution. Research in this area explores the use of microorganisms to induce calcium carbonate precipitation, thereby enhancing soil strength and stability. The findings provide insights into potential applications in geotechnical engineering and sustainable construction practices. MICP has shown to be a viable and eco-friendly solution when it comes to stabilizing soil. This field of study investigates the use of microorganisms to precipitate calcium carbonate, improving the stability and strength of soil. The results offer perspectives on possible uses in sustainable building methods and geotechnical engineering. This review also examines the role that MICP plays in improving the compressive strength, water absorption, and long-term durability of bricks. The research looks into how microbial activity affects brick microstructure, providing insight into the possibility of improved mechanical qualities. The integration of study results for these three important building materials demonstrates the versatility and encouraging results of MICP. By providing a thorough understanding of MICP applications in concrete, soil, and brick renovations, this review hopes to be a useful tool for researchers, engineers, and industry professionals.
