摘　　要：研究应变硬化水泥基材料(SHCC)和掺入硅烷乳液的整体防水水泥基复合材料(IWR-SHCC)在单轴荷载作用下的渗透性能。对SHCC和IWR-SHCC试件进行单轴拉伸试验,待试件达到不同拉伸应变后开展渗透性试验,测试SHCC和IWR-SHCC试件在直拉荷载作用下水和氯离子渗透量。结果表明,水和氯离子渗透量均随着拉伸应变的增加而增大,尤其在较高应变下,渗透率和渗透量增加愈为明显;但是在相同拉伸应变下,IWR-SHCC试件较SHCC试件具有更好的抗水和氯离子侵入性能。This paper aims to investigate the influence of uniaxial tension load on the permeability of SHCC and IWR-SHCC. The uniaxial tensile test was first carried out,and then the permeability test was carried out after different tensile strains were applied to the SHCC and IWR-SHCC. Furthermore,the water and chloride penetration content were determined. The results show that the content of water and chloride penetration increases with the increase of tensile strains. Especially for the specimens suffered a high tensile strain,the increment becomes more obvious. However, the IWR-SHCC possesses a better resistance to the water and chloride penetrations than that of SHCC under the same tensile strain.
