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 kiln. The 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 different sizes and densities. LECA is used to make lightweight concrete products and other uses.

Expanded clay about the raw material clay and the
After the clay is dried at temperatures of 300 to 800 °C while simultaneously being crushed and granulated by equipment inside the kiln, the actual expansion process occurs at a temperature of approx. 1200 °C. The shell of the clay pellets reaches the melting point and sinters, which means that it fuses together and thereby becomes more compact.
