LECA is produced in many countries (more than twenty countries) with various products name. Particular countries produce LECA with approximately similar method such as UK, Iran, Portugal, …
view more· 3.1.12 Lightweight expanded clay aggregate (LECA) LECA [80,98,112–114] is a cellular material produced exploiting the clay expansion processes at high temperatures. The granular material can be used loose or mixed with plaster. It is also used to produce lightweight concrete [115]. The thermal conductivity of these materials is quite high (0. ...

The first known construction to use LWAC is more than 2000 years old using natural volcanic materials. Among several structures to utilize LWAC at that time is the Coliseum in Rome the most well-known.
