Aerated Concrete: Methods, Uses and Properties

The skin of cells or voids must be able to withstand mixing and compaction pressure. This resulting concrete is known as aerated or cellular concrete, but strictly speaking, the use of word concrete is not appropriate as no coarse aggregate is used in it. Properties of Aerated Concrete: Aerated Concrete has the following properties: 1.
