摘　　要：通过工程实例,介绍了某市人民医院病房大楼地下混凝土工程施工中碱骨料活性检测和采用粉煤灰掺合料抑制混凝土碱骨料活性反应技术,经试验检测和实际应用,粉煤灰掺量达到合理配合比时,其抑制碱骨料活性反应效果良好,强度可得到保证。并且混凝土的密实性、和易性和抗渗性得到进一步提高。这对有相似情况碱活性骨料的混凝土施工具有一定借鉴意义和推广价值。This paper introduced the application of technique about inhibition of alkali - aggregate reaction with fly ash aggregate in construction. Through the tests of detection and application in engineering practice, good effect was achieved. Concrete properties of density, anti - seepage and strength have been improved, which has certain reference to the sirnilar project.
