混凝土外部硫酸盐侵蚀破坏的研究

硫酸盐侵蚀是影响混凝土耐久性的重要因素之一。对于混凝土硫酸盐侵蚀问题的研究具有重要的意义。主要研究了外界环境中硫酸盐对混凝土的侵蚀破坏,从物理硫酸盐侵蚀和化学硫酸盐侵蚀两方面论述了混凝土外部硫酸盐侵蚀的类型及破坏特征,并对外部硫酸盐侵蚀过程中石膏的形成作为膨胀源进行了讨论。

STUDIES ON EXTERNAL SULFATE ATTACK ON CONCRETE

Sulfate attack is one of the important factors influencing concrete durability.The research on sulfate attack on concrete is very significant.It is reviewed the effects of the sulfate from the external environment.The types and the damage characteristics of external sulfate attack on concrete from two aspects including physical sulfate attack and chemical sulfate attack are elaborated.Gypsum formation as the cause of expansion in external sulfate attack is also discussed.
