| 摘 要： | 结合三河口工程实际,采用碱骨料鉴定的岩相法、砂浆棒快速法、砂浆测长法对该工程拟采用骨料进行了检测,并对鉴定为活性的人工骨料进行了抑制效能试验,结果表明:只要掺加20%以上的粉煤灰就可抑制碱骨料反应。

| Abstract: | in combination with the engineering practice of Sanhekou project, lithofacies method, quick mortar stick method and mortar length measurement method are applied to inspect alkaline aggregates. Furthermore, tests on the restraining effects of the artificial aggre- gates verified with alkaline activity are performed. The tests show that the reaction of the alkaline aggregates can be restrained as long as over 20% flyash is mixed. |

| Keywords: | aggregate alkaline activity type restraining scheme |
