Polymer-Enhanced Bacterial Self-Healing Concrete for Sustainable, Eco-Friendly Infrastructure

The formation of micro-fractures in concrete is a naturally occurring phenomenon. The incorporation of bacteria into concrete has been shown to enhance its durability and mechanical properties. Super absorbent polymers have the capability to absorb water, afterwards undergoing crystallization. The potential remediation of structural degradation and cracks in bio-concrete can be achieved through the incorporation of super-absorbent polymers. The primary objective of this study is to examine the key attributes of research conducted on polymer modified self-healing concrete. In this study, the addition of Bacillus subtilis at a concentration of 105 cells/mL and sodium polyacrylate to concrete is considered. However, the use of technologies aimed at enhancing self-healing capabilities, such as the integration of advanced chemical healing mechanisms, significantly escalates the expenses associated with the fabrication of self-repair concrete structures. The utilization of recycled industrial waste material in the composition of self-healing concrete mixture contributes to the advancement of environmentally sustainable practices and has been recognized for its ability to produce cost-effective self-healing concrete structures.
