摘要
结合工程实际,采用ASTM法,砂浆棒快速法、砂浆长度法及混凝土棱柱体法抑制试验,对粉煤灰抑制碱硅酸反应(ASR)的有效性进行了试验研究,并结合试验成果对粉煤灰抑制机理和抑制试验的方法进行了分析和讨论。
Based on the actual engineering situations, the effectiveness of flyash in restraining alkali -silica reaction （ASR） has been tested by the ASTM method, the accelerated mortar bar method, the mortar length method and the concrete prism method. According to test results, the paper analyzes the restraining mechanism of flyash and test methods.
