| 摘 要： | 表面防水处理通过改变混凝土的表面性质来阻止或延缓水和氯离子等有害物质侵入,从而延迟混凝土劣化,提高混凝土的耐久性。为了揭示对既有混凝土结构进行耐久性修复时,有机硅防水处理技术的可行性,对2种不同湿度条件下的混凝土进行了防水处理,通过比较毛细吸水系数的变化,发现有机硅表面防水处理的防水效果随湿度的增加而降低。

| Abstract: | Superficial water repellent treatment can prevent or delay corrosive substance such as water and chloride ion ingress into concrete by changing the superficial property of concrete,and then delay deterioration of concrete and improve the durability of concrete.In order to reveal the feasibility of organosilicon water repellent treatment technology when restore the durability of existing concrete structure,water repellent treatment is carried out on concrete under two different humidities,and compares the coefficient of capillary suction.It is found that the efficiency of water repellent treatment decreases with the increase of humidity. |

| Keywords: | superficial water repellent treatment coefficient of capillary suction content of water impregnation depth organosilicon water repellent agent |
