Aggregate Size On Lightweight Concrete

Lightweight concrete is made using lightweight aggregates of expanded shale, clay and slag. These are used to produce structural lightweight concrete with a freshly mixed unit weight of 90 to 120 pounds per cubic foot. Normal weight concrete is typically 135 to 150 pounds per cubic foot.
