Thermolitys®: A new high-performance foamed concrete

The Thermolitys® concretes developed in this study are a range of lightweight concretes that result from introducing a foaming agent while mixing a low water/binder ratio and a high packing-density cementitious paste.

Examples of compositions and their technical, economical and environmental characteristics are presented.

The invention has been patented by Cerib and the Thermolitys™ trademark has been registered.

Interests and limits of the material are discussed. It appears that its area of interest predominantly lies between autoclaved cellular concretes and lightweight aggregate concretes.
