Growth environment optimization for inducing bacterial mineralization and its application in concrete healing

Bacterial-based healing is a promising solution for sustainable concrete maintenance. The purpose of this research was to heal the concrete cracks with Bacillus cereus as a healing agent. The bacteria strain was a dominant strain isolated from carbide slag. The effects of different environments on the growth and urease activities of bacteria were studied first. Secondly, healing capacity was evaluated by water absorption, water permeability,...
