A systematic review of bacteria-based self-healing concrete
The common properties of this concrete stay the same while using the bacteria and calcium lactate tend to increase the concrete compaction. Here, the calcium lactate is used as a food for the bacteria which helps minor cracks with ∼0.4 mm width to be healed through bacteria reaction [3, 16]. Download : Download high-res image (487KB)

AUTOGENOUS HEALING: A CONCRETE MIRACLE?
Autogenous healing of concrete occurs when continuity between two sides of a crack is restored without a deliberate external intervention or repair. In most cases, the cracks are narrow and caused by shrinkage extensive enough to induce locally a strain larger than the tensile strain capacity of the concrete. The presence of water is necessary ...
