Lightweight Expanded Clay Aggregate. What is LECA? LECA stands for lightweight expanded clay aggregate. Pre-treated clay is baked in a rotary kiln at over 2000°F into small size balls from 4mm to 25mm in diameter. Once baked, the expanded nature of the clay makes it extremely light with balls measuring around 250 kg/㎥.
