context_page_description: Foam concrete, also known as Lightweight Cellular Concrete, Low Density Cellular Concrete, and other terms is defined as a cement-based slurry, with a minimum of 20% foam entrained into the plastic mortar. As mostly no coarse aggregate is used for production of foam concrete the correct term would be called mortar instead of concrete; it may be called "foamed cement" as well. The density of foam concrete usually varies from 400 kg/m³ to 1600 kg/m³. The density is normally controlled by substituting fully or part of the fine aggregate with foam.
context_section_description: Foam concrete is a versatile building material with a simple production method that is relatively inexpensive compared to autoclave aerated concrete. Foam concrete compounds utilising fly ash in the slurry mix is cheaper still, and has less environmental impact. Foam concrete is produced in a variety of densities from 200 kg/m³ to 1,600 kg/m³ depending on the application. Lighter density products may be cut into different sizes. While the product is considered a form of concrete (with air bubbles replacing aggregate), its high thermal and acoustical insulating qualities make it a very different application than conventional concrete.
