    摘要： A cementitious composition comprises (a) an hydraulic cement comprising at least 65% by weight of hydraulic calcium silicate, e.g. tricalciuin silicate, and (b) a water-soluble or water-dispersible organic polymer. The hydraulic cement preferably comprises not more than 7% by weight of Al 2 O 3 , not more than 6% by weight of Fe 2 0 3 and not more than 4% by weight of S0 3 , and may be partially replaced by a mineral aggregate or extender. The polymer is present in an amount of up to 15% by weight of the cement and other mineral components and is preferably a partially hydrolysed poly(vinyl acetate). The compositions are rendered settable by the inclusion of water, the set products having excellent wet dimensional stability.

    摘要翻译： 水泥质组合物包含（a）包含至少65重量％的水硬性硅酸钙的水硬性水泥， 硅酸三钙，和（b）水溶性或水分散性有机聚合物。 水硬性水泥优选包含不超过7重量％的Al 2 O 3，不超过6重量％的Fe 2 O 3和不超过4重量％的SO 3，并且可以部分地由矿物骨料或增量剂代替。 聚合物的存在量高达水泥和其他矿物组分的15重量％，优选部分水解的聚（乙酸乙烯酯）。 通过包含水使组合物变得可凝固，凝固产品具有优异的湿尺寸稳定性。
