A review paper on performance evaluation of bacteria induced concrete for rigid pavements

Concrete is a foundational material renowned for its performance across a spectrum of applications in construction and infrastructure. it is indispensable in meeting the diverse demands of modern engineering and architecture, from towering skyscrapers to intricate bridges, from residential homes to transportation networks, concrete's performance capabilities have shaped the built environment in profound ways. But conventional concrete is susceptibility to cracking, especially under tensile stresses. This can compromise the structural integrity of concrete elements and lead to durability issues and reduced service life. Rigid pavements are vulnerable to cracking due to temperature changes, shrinkage, and severe loads. Cracks have the potential to undermine the pavement's structural integrity, hastening deterioration and raising maintenance requirements. Review paper describes the method that is used in showing the performance Evaluation of concrete Through the process of carbonate ion formation, a microorganism secretes calcium precipitate externally, forming CaCo3. This fills in the holes in the concrete texture, increasing its compactness. Conversely because of the expansion of the filler fabric inside the concrete mixer's pores, this improves the strength of the concrete. In the laboratory tests has been carried out to study the impact of introducing bacteria on concrete. here compressive strength, flexure strength, split tensile strength and durability test on Bacteria induced Concrete is studied and SEM and XRD analysis is also carried about to the study the microstructure of Bacteria induced concrete.
