| 摘 要： | 将有机表面活性物质和粉煤灰作为复合减水剂掺加到建筑石膏中,建筑石膏的拌和用水量减少,结构变得致密,抗压强度和抗折强度提高。复合减水剂掺量在5%时,抗压强度和抗折强度最高,减水率>15%,效果较好。

| Abstract: | The water needed by gypsum decreases,the structure becomes more compact and the compressive strength and bending strength improves by adding organic active agent and fly ash,as composite water reducer,to the building gypsum.When the composite water reducer amounts to 5 %,the compressive strength and bending strength rise to the highest and when the water amount reduced is>15 %,the best effect is obtained. |
