制备了内掺硅烷乳液的防水砂浆试件,通过四点弯曲试验使试件受到不同的外部应力作用,对受力后的试件进行毛细吸收试验,测定其抗水渗透和抗氯离子渗透性能。结果表明,空白试件和内掺试件的抗渗透性随着应力的增加而减少;但是,与空白试件相比,内掺试件在不同外部应力环境下均具有良好的抗渗透性。
The waterproof mortar sample with silane coupling agent was prepared. The specimens were subjected to different external stress through four-point bending test. The specimens were subjected to capillary absorption test to determine the resistance to water penetration and chloride ion penetration . The results show that the impermeability of blank specimens and inner specimens decreases with the increase of stress. However, compared with the blank specimens, the inner specimens have good permeability under different external stress environment.
