摘要
通过砂浆棒快速法考察掺入粉煤灰和锂盐对砂浆棒膨胀率的影响,研究向水泥砂浆中同时添加粉煤灰和锂盐对碱集料反应(AAR)的抑制效果。结果表明,适量掺入粉煤灰和锂盐可以较好的起到对碱集料反应的抑制作用。
Study on the effect of fly ash and lithium salt on expansion rate of mortar stick by the fast mortar stick method. Discuss the effect of filling fly ash and lithium salt in mortar stick at the same time on restraining alkali-aggregate reaction. The result indicated that mixing into the fly ash and the lithium salt right amount may suppress the sample＇s expansion made by alkali-aggregate reaction
