高性能FKJ混凝土耐腐蚀性快速试验方法探讨

RESEARCH ON QUICK TESTING METHODS FOR RESISTANCE TO CHEMICAL ATTACK ON HIGH-PERFORMANCE FKJ CONCRETE

文中着重分析采用（H2SO4＋HCl＋HNO3）混合酸和NaOH溶液作为快速试验方法侵蚀介质之理由，拟定了10％浓度的混合酸和10％浓度的碱液，反应温度为95～100℃的快速试验方法[5]，并对试验结果作了分析。文中也探索了快速试验结果与实际应用环境的联系，即根据试验结果预测FKJ混凝土在PH＝2～13使用环境下的耐久性。

This paper emphatically analyzes the reason that (H2SO4 +HCl +HNO3)mixed acid and NaOH solution are used as attack media for the quick testing method,works out the quick testing method with the mixed acid of 10%concentration and the alkali solution of 10% concentration and at 95~ 100℃ reaction temperature,and analyzes the testing results. The relations between the quick testing results and actual usc conditions,i. e. how to predict the durability of FKJ concrete under use conditions of PH= 2~ 13 according to testing results,are also studied in this paper.
