What Exactly Is Lightweight Concrete Specify Concrete

Apr 25, 2019 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 lbft , whereas the density of regular weight concrete ranges from

What Is Lightweight Aggregate Concrete And Its Uses

The lightweight aggregate is a kind of coarse aggregate which is used in the production of lightweight concrete products like concrete block, structural concrete, and pavement. The shape of the lightweight aggregate used in concrete can be cubical, rounded, angular, or of any other shape. The shape and texture can directly affect its workability.
