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 and texture can directly affect its workability. The compressive strength level .
