Self-Healing Concrete

Researchers at the Delft University of Technology in the Netherlands are working on placing bacteria in concrete mixes to fix cracks in concrete and make it self-healing. This could make concrete less susceptible to damage related to water that infiltrates a beam by way of a crack and results in rebar corrosion.
