What Exactly Is Lightweight Concrete? Specify Concrete

Apr 25, 2019  W hat Is Lightweight Concrete?. 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.

Structural Lightweight Concrete Concrete Construction ...

Dec 02, 2010  A: Structural lightweight concrete (SLC) is made with lightweight aggregates (such as expanded clay, slate, or shale; pelletized or extruded fly ash; or expanded slag) either alone or combined with normal weight aggregates. It is used to reduce the dead load of concrete members, such as floor slabs in high-rise buildings.
