矿物掺合料对混凝土抗氯离子渗透性的影响综述

An Overview on Influence of Mineral Admixture on Chloride Ion Penetration Resistance of Concrete

矿物掺合料因对改善混凝土抗氯离子渗透性有着较为显著的作用而获得了研究者的广泛关注。综述了近年来国内外关于矿物掺合料对混凝土抗氯离子侵蚀能力影响的研究进展,分析并总结了粉煤灰、硅灰、矿渣等矿物掺合料单掺和复掺的情况下,对混凝土抗氯离子渗透性能的影响。同时,通过分析混凝土抗氯离子渗透性相关测试方法的优缺点,并对比不同研究者的测试结果,对需要进一步研究的相关问题提出了建议。

Mineral admixture has been attracting increasing attention by the researchers, because of its significantly effect to improve the concrete resistance to chloride ion permeability. The research progress of mineral admix- ture of concrete resistance to chloride ion erosion capacity at home and abroad in recent years are reviewed, the influence of chloride resistance of concrete are analyzed after separate or composite mixed with the mineral admixture in- cluding fly ash, silica fume and slag into concrete. Meanwhile, through the anaIysis of advantages and disadvantages of the related method of the test and comparing the different results of the researchers, then some suggestions for the problems which need to be further studied are put forward.
