Lightweight Insulating Structural Concrete
US Patent:
4268317, May 19, 1981
Filed:
Dec 22, 1978
Appl. No.:
5/972611
Inventors:

US Classification:

Abstract:
A lightweight insulative, structural concrete is produced from a cement mix containing lightweight aggregates having precisely defined physical and chemical properties. These aggregates are very low in density and very high in amorphous SiO. sub. 2 content. The concrete product produced using the mix of this invention has a unique combination of high structural strength (up to 3400 psi, 28-day compressive), low density (50 to 110 pounds per cubic foot) and high thermal resistance (R) values (up to 3. 16/inch). Such a product is just as strong, one half the weight, and 36 times more insulative than ordinary hard rock concrete.
