Solid concrete blocks are obtained from lightweight aggregates while hollow concrete blocks are obtained from heavy aggregates.

Solid concrete blocks are obtained from lightweight aggregates while hollow concrete blocks are obtained from heavy aggregates. Correct Answer False

Concrete masonry uses two types of cement concrete blocks for the construction of walls – hollow concrete block and solid concrete block. Solid concrete blocks are obtained from heavy aggregates while hollow concrete blocks are obtained from lightweight aggregates.
