Several types of foam concrete are different: thermal insulation, structural-the-insulating, structural.
Foam concrete blocks were invented back in the 19th century. In those days, builders in cement-knowing solution mixed bull blood, which contributed to the formation of foam. After hardening the solution, a strong and light material was obtained. However, then this building material was not widespread. On an industrial scale, foam concrete began only at the end of the 20th century, after the introduction of new technologies.
