Abstract

L'invention concerne un produit obtenu à partir d'une dispersion de sulfate de calcium aqueuse durcissable présentant un rapport eau-matières solides inférieur à 0,4-1 et contenant des corps creux légers répartis dans la solution qui comportent des surfaces imperméables à l'eau (telles que des billes de polystyrène expansé). La dispersion contient un ciment hydratable (tel que le sulfoaluminate de calcium) pouvant être hydraté en présence de la dispersion de sulfate de calcium. Ce ciment hydratable réagit avec l'eau excédentaire de la dispersion, ce qui améliore la résistance à l'eau du produit résultant.
