摘　　要：采用有机硅防水剂对混凝土试件进行表面处理,通过对比在不同盐冻环境下、不同有机硅防水剂涂覆量的混凝土试件的毛细吸水结果,判定其渗透性。结果表明,在未受盐冻损伤时,表面处理过的混凝土试件具有良好的抗渗透性;在经受不同循环的盐冻损伤后,表面处理过的混凝土试件仍具有较好的抵抗水分侵入的能力;采用有机硅防水剂对混凝土试件进行表面处理能提高混凝土的抗渗透性。The permeability of concrete coated with organosilicon waterproofing agent with different dosages and under different damages of frost-salt environment was studied by capillary absorption test. The results showed that the surface- treated concrete had good anti-permeability when it did not suffer from frost-salt action. Moreover, the surface-treated concrete still showed good water resistance under different damages of frost-salt environment. Therefore, the concrete coated with organosilicon waterproofing agent had good water impermeability.
