Self Healing Concrete

Self Healing Concrete

According to an article in New Scientist , concrete will soon be able to heal hairline fractures.

“Like living bone, concrete could soon be healing its own hairline fractures – with bacteria in the role of osteoblast cells. Worked into the concrete from the beginning, these water-activated bacteria would munch food provided in the mix to patch up cracks and small holes.Concrete reinforced with steel forms the skeleton of many buildings and bridges. But any cracks in its gritty exterior make it vulnerable: “Water is the culprit for concrete because it enters the cracks and it brings aggressive chemicals with it,” says Henk Jonkers of Delft University of Technology in Delft, the Netherlands. These chemicals degrade both concrete and steel.”Think of the labor saved on bridge maintenance alone! There is no mention of when this new concrete will be available.
