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。
The ordinary concrete specimens with different water-cement ratio and the silane surface waterproof concrete specimens were subjected to the freeze-thaw cycle test and the compressive strength test, and then the durability and mechanical properties of the silane surface waterproof concrete were comprehensively evaluated. The test results show that the frost resistance of concrete specimens is inversely proportional to the water-cement ratio. Under the same freeze-thaw cycles, the water-repellent properties and mechanical properties of the concrete can be improved by the silane surface waterproofing treatment.
