| 摘 要： | 对内掺硅烷乳液的防水混凝土进行耐久性试验,包括不同硅烷乳液掺量下混凝土的抗压强度试验、毛细吸水试验、渗透试验和抗冻试验.结果表明,内掺硅烷乳液的防水混凝土在毛细吸收和静水压力作用下有很好的抵抗水分侵入的能力.但是,由于硅烷颗粒的存在减缓了水泥的水化作用,使得内掺硅烷乳液的防水混凝土的抗压强度及抗冻性能较空白混凝土下降；并且随着硅烷掺入量的增加,其抗压强度降低、抗冻性能变差.

| Abstract: | This article studies durability of waterproofing concrete adding silicane emulsion by tests,such as compression strength test,capillary absorption test,permeability test and frost resistance test.The results show that waterproofing concrete adding silicane emulsion has good water impermeability under capillary absorption and hydrostatic pressure.But the compression strength and frost resistance of the waterproofing concrete are all lower than that of control group because the existence of silicane grain slows down the hydration of the concrete.And the compression strength and frost resistance decrease with the increasing of the content of silicane emulsion. |

| Keywords: | silicane emulsion waterproofing concrete compression strength permeability freeze-thaw cycle |
