Abstract

The invention provides a process in which the usual sulphate carriers in cellular concrete, like gypsum, hemi-hydrate or anhydrite, are at least partly replaced by calcium aluminate sulphates and/or calcium aluminate sulphohydrates. This reduces or even prevents lime agglomerations, delays in lime hydration and post-formation of the cut cellular concrete cakes. In addition, the process of the invention makes it possible to reduce the number of forms to be used, even down to a single one.
