摘　　要：砂浆的吸水性和不透水性与其孔结构密切相关,研究了不同品种的憎水剂和消泡剂种类和掺量对聚合物砂浆吸水率、软化系数、不透水性和孔结构的影响,结果表明,硬脂酸类憎水剂(C)-有机硅类消泡剂(B)与成品聚合物砂浆的配伍效果最好,砂浆的吸水率降低、不透水性和软化系数提高。The water absorption and impermeability of mortar has close correlation with pore structure. Different kinds of water-repelling agent and anti-foaming agent are chosen. The effect of kind and content of addition agent on water absorption, softening coefficient, impermeability and pore structure of polymer mortar has been studied. The results show that stearic acid water-repelling agent C and organosilicon anti-foaming agent B have the best compatibility with polymer mortar, the water absorption of mortar reduces and its impermeability and softening coefficient increase.
