  • What Exactly Is Lightweight Concrete? Specify Concrete

    2019-04-25  Lightweight concrete is a mixture made with lightweight coarse aggregates such as shale, clay, or slate, which give it its characteristic low density. Structural lightweight concrete has an in-place density of 90 to 115 lb/ft³, whereas the density of regular weight concrete ranges from 140 to 150 lb/ft³. This makes lightweight concrete ideal for building modern structures that require ...
