Imagine hitting a building with a hammer. A large chunk is knocked loose. Now as you watch the concrete begins to repair itself like the T-1000 in Terminator 2.
Science fiction right? Well yes, but Dutch scientists have developed a bioconcrete that repairs the micro-fractures that lead to building decay. This could lead to more structurally secure, more durable and longer lasting buildings. The leader of the project, professor Henk Jonkers of Delft University of Technology in the Netherlands, accomplished this by inserting bacteria held inside capsules. When water begins to enter through a micro-fracture the capsule releases the bacteria, which begins to feed and excrete limestone healing the concrete. And who knows maybe as they perfect it, one day concrete will insta-heal any damage, no matter how big.
