2. Main lightweight aggregates
2.1 Expanded clay
Expanded clay is a material obtained by high-temperature heating of specific clays, which expand due to the release of internal gases. This process produces lightweight, cellular-textured aggregates with a true density generally ranging from 700 to 1,000 kg/m 3 . However, recent advances now make it possible to produce even lighter aggregates, with densities of between 250 and 850 kg/m 3 ...
