Abstract

Process for the manufacture of molded and light objects of alpha gypsum, as construction elements, by the mixture of alpha gypsum with water and mold casting, characterized in that it consists of finely grinding the alpha gypsum, mixing it with finely divided lime, making The whole suspension in water shaking until a homogeneous paste is obtained, in adding to this an amount of sulfuric acid that does not exceed the stoichiometric amount equivalent to the amount of lime, expressed in CaO, in stirring the mixture and quickly casting the mold.
