ECA® stands for Expanded Clay Aggregate. It is a type of lightweight aggregate made from natural clay. The clay is pelletized and then processed in rotary kilns at temperatures of up to 1200°C (2192°F). This causes the clay to expand into lightweight, porous granules. These granules are characterized by a closed, almost round structure and a

Expanded clay (LECA) and other light weight aggregates such as: expanded shale, pumice, slate, perlite, bottom ash etc. have been successfully used in the production of

Expanded clay is produced from naturally and abundantly available clay. The clay is extracted, pre-treated and introduced to rotary kilns. These kilns are heated to temperatures up to 1.150 ºC and this process transforms the clay into various sized lightweight aggregates with a hard ceramic shell and a porous core.

 — In most light weight aggregates as the size of aggregate increases the strength and bulk density of the aggregate decrease. Using very big size light weight aggregate with a lower strength results in a lower strength of the light weight concrete; therefore, biggest size of the light weight aggregate must be limited to 25 mm at most. 3. …
