摘要
对不同冻融损伤下的混凝土试件采用有机硅防水剂进行表面防水处理,通过对比不同有机硅防水剂用量下混凝土试件的毛细吸水试验、氯离子自由扩散试验,研究冻融损伤修复后混凝土的耐久性。结果表明,对比空白混凝土试件,采用有机硅防水剂修复的冻融损伤混凝土试件,其毛细吸水系数和氯离子侵入含量大大降低,具有良好的抗渗透性和耐久性能。
The samples of concrete with varying degrees of freezing-thawing damage were treated with organosilicon waterproofing agent. The durability of the samples applied with different dosages of organosilicon waterproofing agent was studied by test of capillary water absorption and chloride ion free diffusion. The results showed that compared with the blank sample, the samples had good anti-permeability and durability and their capillary water absorption coefficient and content of chloride ion were lower than that of blanket sample.
