摘　　要：混凝土碱-硅酸反应(Alkali-Silica Reaction,简称ASR)是降低混凝土耐久性的主要原因,不仅会影响建筑结构的稳定性,还会增加维修成本。通过快速砂浆棒试验探究了稻壳灰(Rice Hush Ash,简称RHA)对ASR的抑制作用,结合力学性能试验,得到了掺入RHA的最佳质量分数。结果表明:单掺RHA可以有效抑制ASR,掺入RHA最佳质量分数为10%。As the most important factor affecting the concrete durability,the Alkali-Silica Reaction(ASR)of concrete will not only affect the long-term use safety of buildings,but also increase the engineering cost.Through accelerated mortar bar test,the inhibitory effect of Rice Hush Ash(RHA)on the ASR was explored,combined with mechanical properties test,the optimum ration was determined.The results show that RHA can significantly inhibit ASR,and the optimum dosage is 10%.
