Abstract:
A gypsum composition is prepared to prolong the working time and shorten the setting time of the gypsum composition in a bone restoration operation. The gypsum composition is formed of a half-hydrate gypsum (CaSO4.0.5H2O), and an aqueous solution containing water, a polyol, and at least one solidification promoter selected from a polysaccharide, a polyethylene alcohol or mixtures thereof. The aqueous solution contains the water and the polyol in a volume ratio ranging between 25:1 and 2:1. The aqueous solution further contains 0.2% to 2.0% by weight of the solidification promoter.
