摘　　要：在不同温度条件下，将花岗岩石块浸入硅烷偶联剂溶液并放置一段时间进行干燥后，再与水泥浆配合制成界面层劈拉试件。结果表明，常温下使用偶联剂的花岗岩与水泥浆的界面层劈拉强度提高幅度最大。探讨温度和浸泡时间对花岗岩／偶联剂／水泥浆界面层劈拉强度的影响机理。Granite blocks were immersed in silane coupling agent（SCA） in different temperature levels for different periods, and then were dried and used for producing spliting tensile specimens with cement paste. The test results indicated that the greatest increase of spliting tensile strength of granite/silane coupling agent/cement paste interface was obtained at indoor temperature. The influencing mechanism of temperature and immersing period on spliting tensile strength of granite/silane coupling agent/cement paste interface was discussed.
