The shape of an individual pellet can be irregular or uniform depending on brand and manufacturing process. The manufacturers consider expanded clay to be an ecologically sustainable and reusable growing medium because of its ability to be cleaned and sterilized, typically by washing in solutions of white vinegar, chlorine bleach, or hydrogen ...

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 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 .

The process of creating light expanded clay aggregate can be finetuned to create LECA, ECA® of varying densities and sizes. Light expanded clay aggregate is one of the best lightweight aggregates for use in readymix concrete and precast concrete, and has lots of benefits when used in structural lightweight concrete appliions, especially when compared to other lightweight aggregates ...
