Bio-healing for micro-crack treatment in cementitious materials: Toward a quantitative assessment of bacterial efficiency

Bio-healing is a promising approach to enhancing natural self-healing and thus completely heal large micro-cracks (> 200 ?m) in cementitious materials. The aim of this research is to better understand bio-healing of cementitious materials in order to accelerate the healing kinetics and maximize sealing efficiency of large micro-cracks. The bio...

Experimental studies of self-healing cementitious materials incorporating mineral admixtures

In order to limit the release of CO2 produced in cement manufacturing, clinker (the major cement component) is often partially replaced by mineral admixtures like blastfurnace slag. The use of mineral admixtures presents different advantages such as the recycling of industrial waste and the improvement of different material properties ...
