Heat-expanded lightweight pebbles. 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.
After many years of exploration and attempt, EPS lightweight concrete can be used in many building structures, such as EPS insulation coating, EPS mortar, EPS sealing putty, EPS lightweight mortar, EPS concrete inner and outer wall panels, etc. [4] In addition, EPS lightweight aggregate concrete is also used in the fields of pavement backfill ...
[1] [2] There are thousands of aggregate-producing companies in the US, operating in each of the 50 states, and employing 105,000 people. Most aggregate is used by the construction industry, where it is an essential raw material and the main ingredient in concrete and asphalt concrete .
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, calcined gypsum, lime, portland cement, water, and aluminium powder.
Lightweight (i.e. low density) ECC have been developed through the addition of air voids, glass bubbles, polymer spheres, and/or lightweight aggregate. Compared to other lightweight concretes, lightweight ECC has superior ductility. Applications include floating homes, barges, and canoes.
