摘　　要：对不同水灰比的普通混凝土试件和硅烷表面防水混凝土试件进行冻融循环试验和抗压性能试验,进而综合评定硅烷表面防水混凝土的耐久性及力学性能。试验结果表明,混凝土试件的抗冻性能与水灰比成反比;在相同冻融循环次数下,对混凝土进行硅烷表面防水处理可以提高其抗冻性及力学性能。Durability and mechanical properties of ordinary concrete and waterproofing concrete coated with organic silicon of different water cement ratio were comprehensively evaluated by freezing-thawing cycle and compressive tests.The results showed that freezing resistance was inversely proportional to water cement ratio.Besides,under the same times of freezingthawing cycles,the freezing resistance and mechanical properties of concrete can be improved by waterproof treatment of coating with organic silicon.
