You’d think that concrete would last forever. After all, it’s pourable stone, so it should hang around as long as the Rock of Gibraltar. But, under the right (or wrong) conditions, concrete decays with alarming speed. To combat this, researchers at the University of Bath in the UK are working on a self-healing concrete that uses bacteria to seal the cracks that lead to decay. In this way, they hope to cut down on maintenance costs and increase the life of concrete structures.
