ABSTRACT
The use of bacteria to impart self-healing capabilities to cementitious materials has garnered attention in addressing crack propagation issues within Submerged Floating Tunnel structures. Recent investigations into the self-healing performance of bacteria-based cementitious materials have highlighted challenges related to declining bacterial viability, attributable to adverse conditions and limited nutrients within the cementitious materials. This study presents a comprehensive overview of recent literature addressing the self-healing performance of aged bacteria-based cementitious materials, focusing on diverse bacterial strains, carrier for bacteria, and curing conditions for cementitious materials. In addition, a preliminary study examines the bacterial viability and self-healing performance of cementitious materials with different binders.
