A concrete block is one of several precast concrete products used in construction Most concrete blocks have one or more hollow cavities, and their sides may be cast smooth or with a design. Concrete Blocks Concrete blocks The concrete that is commonly used to make concrete blocks is a mixture of powdered portland cement, water, sand, and gravel.
Lightweight concrete mixture is made with a lightweight coarse aggregate and sometimes a portion or entire fine aggregates may be lightweight instead of normal aggregates. Structural lightweight concrete has an in-place density (unit weight) on the order of 90 to 115 lb / ft³ (1440 to 1840 kg/m³ ...
