从US-A-3455710人们知道，用含Si-键合氢原子的有机硅氧烷(H-硅氧烷)浸渗，可以赋于石膏防水性能。该参考文献也介绍了石膏和氢氧化钙混合物用H-硅氧烷的浸渗处理法。但是该H-硅氧烷的防水作用并不能令人满意，而且H-硅氧烷很贵，还可推定其上的氢可与水接触。
US-A4411702介绍由二水合硫酸钙、矿渣及氢氧化钙组分生产的，且在生产该部分组分时，以聚二甲基硅氧烷液体将其处理过的防水成型制品。但聚二甲基硅氧烷液体的防水作用也不能令人满意。
本发明的一个目的是提供低成本并容易加工的防水石膏组合物及可由其生产的成型制品。
本发明提供的防水石膏组合物包括下述组分：
(A)100重量份石膏(gypsum plaster)
