Selection of compositions of light refractory concrete for structural and thermal devices of individual houses

Selected compositions of light refractory concretes on expanded clay aggregate with binders of aluminous cements and high alumina combined binder of alumina cement and water glass, which can be used in heating systems and structures of individual houses. The tests of physical and mechanical properties of the cement paste and extract process of manufacturing the compositions of light refractory concretes are done. Manufacturing process of concrete showed that for producing refractory concretes light may be applied three-component system materials instead of 5-component systems previously used for the manufacture of concrete.
