复合因素作用下混凝土硫酸盐侵蚀的劣化机理

The deterioration mechanism of concrete sulfate erosion under the action of compound factors

阐述了多种环境因素对混凝土硫酸盐侵蚀的劣化机理，结果认为混凝土的劣化与混凝土的渗透性能密切相关，在不同劣化因素的协同作用下，其劣化速率和劣化机理与单个因素作用下有很多不同，为以后的研究与工程实际提供一些参考。

This paper elaborated the deterioration mechanism of various environmental factors to concrete sulfate erosion, the results gained that the deterioration of concrete was closely related to the permeability of concrete, in different deterioration factors synergistic effect, the degradation fate and deterioration mechanism had many differences to individual factor effect, provided some reference for future research and engineering practice.
