Explaining Light Expanded Clay Aggregate For Structural Lightweight Concrete. ECA® is a class of lightweight aggregates made from clay and is used as a lightweight construction material. Light-expanded clay aggregate is made in a rotary kiln, which is heated to a temperature of more than 1200°C. This causes the light-expanded clay aggregate.

Techniclay Expanded Clay Aggregate
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.
