Expandable Clay Aggregates (LECA) (Bragdon, 1996). Gases form as clay materials are fired, causing an expansion that, when cooled, leaves a cellular pore structure in the interior and exterior of the aggregates. The end result of the process is a structural grade lightweight aggregate with a low bulk density (Spomer, 1998).


Production of Expanded Clay Aggregate (ECA) is accomplished by different means. In India, they are produced by expansion of moist clay soil in a rotary kiln. Substituting ordinary sand for some light fine aggregate results to increase the strength of concrete obtained. This increase of strength is noticeable with this reason:
