摘　　要：本文从分子次级键和水盐相平衡的观点出发,结合混凝土冻害现象、典型特征和试验验证分析,探讨了混凝土盐冻形成的过程和内在机制。提出了：（1）阴离子干扰作用力假说;（2）差异化膨胀应力假说;（3）分层结冰与絮状结晶效应假说等三个假说。从理论上比较完整地解释了和论证了混凝土盐冻作用的机理。同时,指出了提高混凝土抗盐冻能力的技术原理和技术途径,以及今后需要深入研究的几个问题。The viewpoint of this paper are base on Ion-bond and waters and salts phase quilibrium, which are combine with the appearance and typical characteristics of salt scaling as well as test anal- ysis and experiment verification. The paper discusses the salt scaling processing and internal corrosion mechanism on concrete,and puts forward following hypothesis： ①hypothesis of interfere force on nega- tive ion; ②hypothesis of expanding stress differently and ③ hypothesis of the freezing layered and floe- culent crystal effects. The mechanism of salt scaling of concrete is explained and demonstrated theoreti- cally completely. Meanwhile the paper points out technological principles and ways how to improve their ability to resist the concrete salt scaling,and further study issues the in future.
