干湿条件下硫酸盐会对生态透水混凝土侵蚀性分析

Analysis of Sulfate Erosion of Ecological Pervious Concrete under Wet and Dry Conditions

文章利用室内模拟试验法,探讨了生态透水混凝土受干湿条件下硫酸盐的侵蚀作用。结果发现,生态透水混凝土受硫酸盐溶液的侵蚀作用非常明显,硫酸钠溶液的浓度越大侵蚀生态透水混凝土的作用越强。为了改善混凝土耐久性和工程整体施工质量,应适当调整施工工艺和设计参数,充分考虑硫酸盐侵蚀作用合理设计施工方案。

In this paper,the sulfate erosion of eco-permeable concrete under wet and dry conditions was studied by indoor simulation test.The results show that the erosion of eco-pervious concrete by sulfate solution is very obvious,and the higher the concentration of sodium sulfate solution is,the stronger the erosion of eco-pervious concrete is.In order to improve the durability of concrete and the overall construction quality of the project,the construction technology and design parameters should be adjusted appropriately,and the construction scheme should be designed reasonably considering the sulfate erosion.
