Microbial self-healing of cracks in 3D-printed cementitious materials: Use of recycled sand and bentonite as bio-carriers

A bacterial self-healing system for 3D printing of mortars to mitigate shrinkage cracking and improve the durability of printed elements is presented. In this study, the impacts of incorporating Bacillus subtilis (BS) cultures and calcium lactate (CL), optimizing their concentrat...
