Lightweight aggregate - LECA Leca is produced of clay with poor lime content, which is dried and fired in rotary kilns. The kilns shape the clay into pellets and at a tem-perature of 1.150 ºC gas is formed. The gas expands the pellets resulting in high porosity and low-weight properties. The porosity is caved in by a matrix of solid brick-
