ABSTRACT:
Cement compositions which are the products obtained by mixing together and allowing to cure a hydraulic cement, a silica filler, water, an organic polyisocyanate and a polyol, the organic polyisocyanate being employed in an amount sufficient to provide an excess of isocyanate groups over the hydroxyl groups of the polyol. The compositions are particularly suitable for flooring applications and the mixtures, once made up, set very rapidly.
