Micro-cracks in concrete bridges and other constructions made of concrete can get bigger and if not repaired on time can cause big expenditure, or lead to structural failure. Following the self-healing possibilities of the human body, researchers have developed a concrete into which they mix a fungus, called Trichoderma reesei. The fungus is dormant until the first crack appears. Then the dormant spores will germinate, grow, and heal the crack by precipating calcium carbonate.
