In 2001, in an attempt to commercialize the technology they replaced the binding materials with a health-neutral polymer additive. Laboratory tests were completed on fire resistance and compressive tests. This light polystyrene concrete turned out to be structurally stable, light weight (from 100 to 300 kg/m 3) and 100% fire retardant. A ...
Lightweight expanded clay aggregate (LECA) or expanded clay (exclay) is a lightweight aggregate made by heating clay to around 1,200 °C (2,190 °F) in a rotary kiln. The heating process causes gases trapped in the clay to expand, forming thousands of small bubbles and giving the material a porous structure.
Perlite mine in Owens Valley, California. Perlite is a non-renewable resource. The world reserves of perlite are estimated at 700 million tonnes. [4] The confirmed resources of perlite existing in Armenia amount to 150 million m 3, whereas the total amount of projected resources reaches up to 3 billion m 3. [5]
It is created by using small lightweight EPS balls (sometimes called Styrofoam) as an aggregate instead of the crushed stone that is used in regular concrete. [3] It is not as strong as stone-based concrete mixes, but has other advantages such as increased thermal and sound insulation properties, easy shaping and ability to be formed by hand ...
Aerated concrete produced by the addition of an air-entraining agent to the concrete (or a lightweight aggregate such as expanded clay aggregate or cork granules and vermiculite) is sometimes called cellular concrete, lightweight aerated concrete, variable density concrete, Foam Concrete and lightweight or ultra-lightweight concrete, [18] [19 ...
Autoclaved aerated concrete (AAC) is a lightweight, precast, cellular concrete building material. It is eco-friendly, and suitable for producing concrete-like blocks . [ 1 ] It is composed of quartz sand , gypsum , lime , portland cement , water, and aluminium powder .
Foam concrete, also known as Lightweight Cellular Concrete (LCC) and Low Density Cellular Concrete (LDCC), and by other names, is defined as a cement-based slurry, with a minimum of 20% (per volume) foam entrained into the plastic mortar. [1]
Translucent concrete (also: light-transmitting concrete) is a concrete based building material with light-transmissive properties due to embedded light optical elements — usually optical fibers. Light is conducted through the stone from one end to the other. Therefore, the fibers have to go through the whole object.
