摘　　要：在骨料碱-硅酸活性检测方法中,混凝土棱柱体法的试验结果被认为是最接近实际情况的。但在对大渡河金川水电站工程的拟用骨料进行碱活性检测试验时发现,该方法中规定的3种情况可能会得出相互矛盾的结论。为此提出,对于该试验方法中规定的3种情况,应该采用不同的判定标准。The resuh of concrete prism method is considered to be closest to the actual situation in aggregate alkali-silica activity detection. But in the alkali-silica activity test of aggregate which will be used in the construction of Jinchuan Hydropower Station in Dadu River, the test results under the three conditions defined by concrete prism method may be contradict each other. The different criterions for three conditions are proposed to be used.
