Feb , clay is used as a raw material for the production of lightweight aggregates because it is readily processed into suitable granules and forms lowdensity but high strength aggregate particles when sintered at relatively low temperatures the use of waste clay generated by major infrastructure development projects to make,LECA Complete Process System, expanded clay aggregate,,LECA Product Line Working Principle. Lightweight expanded clay aggregate (LECA), also known as expanded clay or even exclay, is a light weight aggregate made by heating clay to around 1,200 °C in a rotary kiln. The yielding gases expand the clay by thousands of small bubbles forming during heating producing a honeycomb structure.
