Expanded clay aggregate Wikipedia
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 kilnThe yielding gases expand the clay by thousands of small bubbles forming during heating producing a honeycomb structure LECA has an approximately round or potato shape due to circular movement in the kiln and is available in[Show full abstract] such as lightweight expanded clay aggregate (LECA) LECA produced in a rotary kiln which is approximately 50% lighter than normal aggregate, which is a new method in(PDF) The strength of lightweight aggregate in concrete
