Lightweight Concrete

 

the general name for a large group of concretes with a density of less than 1,800 kg/m3. Such concretes include aerated and cellular concretes. In modern construction, aerated concrete is widely used for modular and reinforced-concrete structural members and items to lessen the weight of the construction elements and improve the heat-engineering properties of enclosing structures. Cellular concretes are used in making enclosing elements of buildings and thermal insulation.
