干湿条件下透水型生态混凝土抗硫酸盐侵蚀性能试验研究

Experimental study on sulfate resistance of permeable ecological concrete under dry and wet conditions

随着工业化、城镇化的迅速发展,水工建筑的抗硫酸盐侵蚀研究成为广大学者关注的重要领域。文章通过室内模拟试验,探讨了干湿条件下透水型生态混凝土抗硫酸盐侵蚀性能。结果显示,硫酸盐溶液会对生态透水混凝土产生十分明显的侵蚀作用,且硫酸钠溶液的浓度越大,对生态透水混凝土的侵蚀作用越强。在相关河道工程设计建设中必须予以充分考虑,适当调整设计参数和施工工艺,保证工程施工质量和生态透水混凝土的耐久性。

With the rapid development of industrialization and urbanization,the research on sulfate resistance of hydraulic structures has become an important field of attention from the majority of scholars.Through indoor simulation test,this paper discuss the sulfate resistance of previous ecological concrete under dry and wet conditions.The test results show that sulfate solution will have a great erosion effect on ecological permeable concrete,and the higher the concentration of sodium sulfate solution,the stronger the effect on ecological permeable concrete.In the design and construction of relevant river project,thorough consideration should be given to properly adjust the design parameters and construction technology to ensure the construction quality of the project,also the durability of ecological permeable concrete.
