In EU countries and worldly, concrete is the most widely used building material in the world because of its strength and durability, among its other benefits. Concrete also has a certain amount of limitations. They mainly include crack formation over a period of lifetime. Crack formation in reinforced concrete constructions may result to loss of their durability. Ingress water and chemicals can cause premature matrix degradation and corrosion of embedded steel reinforcement in concrete. Regular maintenance and repair of concrete structures is costly and, in some cases, not at possible. One of possible solution for prevention a costly repair, reduce maintenance and increase material durability might be an inclusion of an autonomous self-healing repair mechanism in concrete design technology. This paper describes some types of bacteria, used in self-healing concrete and their effects on different conditions in concrete on the basis of its properties like strength, durability, absorption of water, insertion of chlorides and others.
