摘要
向水泥基复合材料中添加硅烷乳液制备整体防水试件,通过四点弯曲试验,测定试件在不同应力、应变的多缝开裂环境下抗水渗透性能。试验结果表明:对比未掺入硅烷乳液的空白试件,水泥基整体防水试件具有良好的抗水渗透性能,即使在较高的应变环境下,仍能有效的抵抗水分的侵入,从而提高了试件的耐久性能。
It was prepared within the cement-based materials specimen addition with silane emulsion.Through the four-point bending test,the specimen was measured at different stress,different strain resistant to water resistance.The result shows that the cement-based ma-terials specimen addition with silane emulsions have a good performance on penetration resistance compared with the blank sample.Even though under the high strain environment,the sample could resistance to water penetration,which promotes the durability of the concrete.
