摘要:
为测定水泥-矿渣-粉煤灰三元复合体系中矿渣、粉煤灰的反应程度,本文在理论分析的基础上提出了将EDTA-碱溶液和盐酸2种选择性溶剂结合使用,测定该复合体系中矿渣、粉煤灰反应程度的方法.并且应用该方法测定了水泥-矿渣-粉煤灰三元复合体系中矿渣、粉煤灰不同龄期的反应程度,并与它们在二元复合体系中的结果进行比较.试验结果表明该方法可以较精确地测定三元复合体系中矿渣、粉煤灰的反应程度.
Abstract:
To determine the reaction degrees of blast furnace slag(BFS)and fly ash(FA)in hydrating ternary blends composed of BFS, FA and Portland cement, a combined selective dissolution method based on EDTA-alkaline solution extraction method and hydrochloric acid dissolution method is presented. The method was applied to determine the reaction degrees of BFS and FA in the hydrating ternary blends at different ages. Experimental results show that the reaction degrees of BFS and FA can be determined with satisfying accuracy by the method, and the reaction degree of FA can be obtained even more accurately than that of BFS.
