Abstract
A hardenable molding composition comprising hydratable gypsum, a vinyl monomer, a source of hydrogen sulfite ions and water is disclosed. With this molding composition a hardened product can be obtained having high strength due to the combined effect of the hydraulic reaction of the gypsum and the polymerization reaction of the vinyl monomer.
