摘要
Calcined gypsum (stucco) is treated by blending therewith small portions of water (about 1-10% by eight of the stucco), allowing it to heal, and grinding the healed stucco to increase its surface area. This results in a reduction in water demand with good retention of set strength. If the treated calcined gypsum is not used shortly after the healing procedure, it should be dried before grinding to provide storage stability. The reduced water demand is particularly useful in gypsum board manufacture.
