黄河拉西瓦水电站骨料碱活性试验研究

Experimental Study on Active Alkalescency of Aggregates for Laxiwa Hydropower Station on the Yellow River

结合正在建设中的黄河拉西瓦水电站骨料碱活性鉴定试验，从碱骨料反应的定义、分类及反应机理入手，论述了碱骨料反应的必要条件及活性骨料鉴定的岩相法、化学法、砂浆测长法和砂浆棒快速法试验。

Based on experiments of active alkalescency for the aggregates from Laxiwa Hydropower Station, beginning with the definition, classification and reaction mechanism, the necessary terms of alkaline reaction of aggregates were demonstrated. And the petrographic, chemical, measuring length by mortar and speed test with mortar stick methods for testing the active aggregates also mentioned.
