Abstract

Procedure for the production of gypsum foam and its construction elements, characterized in that the gypsum is kneaded with water in the presence of additives that serve to liquefy the gypsum and to adjust the initiation time and the setting time, dispersing in This mixture of gypsum and water, in the presence of foam stabilizing additives, 1 to 30% in relation to gypsum, of a mixture of isocyanate compounds and polyurethane products based on excess isocyanate compounds with one or more compounds of the group of polyesters with content of OH groups, polyesters and compounds with content of amine groups, mixture that after an initiation time, foams and sets after the foaming reaction.
