Concrete - Wikipedia
Different strengths of concrete are used for different purposes. Very low-strength—14 MPa (2,000 psi) or less—concrete may be used when the concrete must be lightweight. Lightweight concrete is often achieved by adding air, foams, or lightweight aggregates, with the …
Construction aggregate - Wikipedia
Construction aggregate, or simply "aggregate", is a broad category of coarse to medium grained particulate material used in construction, including sand, gravel, crushed stone, slag, recycled concrete and geosynthetic aggregates. Aggregates are the most mined materials in the world.

Foam concrete - Wikipedia
Foam concrete, also known as Lightweight Cellular Concrete (LCC), Low Density Cellular Concrete (LDCC), aircrete, foamed concrete, foamcrete, cellular lightweight concrete or reduced density concrete, is defined as a cement based slurry, with a minimum of 20% (per volume) foam entrained into the stone mortar. As mostly no coarse aggregate is used for production of foam concrete the correct ...
Autoclaved aerated concrete - Wikipedia
Autoclaved aerated concrete (AAC) is a lightweight, precast, foam concrete building material suitable for producing concrete masonry unit (CMU) like blocks. Composed of quartz sand, calcined gypsum, lime, cement, water and aluminum powder, AAC products are cured under heat and pressure in an autoclave.
What is Lightweight Concrete? -Types, Uses and Advantages
What is Lightweight Concrete? 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).
Understanding Different Types of Lightweight Concrete
Low-Density Natural Aggregate Concrete. Most low-density aggregates are volcanic in origin and include pumice, tuff, scoria, and cinders. Diatomite is also something used as the aggregate component of lightweight concretes. The advantage to these types of aggregate is that they often do not require processing apart from crushing or screening.
