Structural Lightweight Concrete

Consult the lightweight aggregate suppliers for detailed mix design information and material capabilities (i.e., unit weight, strength, etc.). Specify 4 to 7 percent air entrainment for pumpability, workability, finishability, and durability. Specify the maximum size aggregate rather than specifying individual sizes.

Structural Lightweight Concrete — What, why, & how ...

Lightweight concrete can be manufactured with a combination of fine and coarse lightweight aggregate or coarse lightweight aggregate and normal weight fine aggregate. Complete replacement of normal weight fine aggregate with a lightweight aggregate will decrease the concrete density by approximately 10 lb/ft3 (160 kg/m3).

The effects of aggregate properties on lightweight concrete

When porous lightweight aggregate is used, the adhesion of the aggregate materials to the cement paste depends mainly on the pore size characteristic of the aggregate surface . It is believed that the interfacial zone of lightweight concrete should be of lesser dimension than that of normal-weight concrete.
