LECA-Lightweight Expanded Clay Aggregate
Lightweight Expanded Clay Aggregate (Leca, Light Weight Expanded Clay Pebbles, Expanded clay) is made from 100% natural clay at average 1200 degree in rotary kiln, the Yielding gases are expanded by thousands of small bubbles as long as this temperature and porosity will appear by many voids and honeycombs at these round shape aggregates when melted materials become cold. ttles in all shapes.
