| 摘 要： | 在总结现有混凝土硫酸盐侵蚀试验研究的基础上,提出了考虑亚高温水淬与硫酸盐侵蚀双因素影响的亚高温环境下混凝土耐硫酸盐侵蚀试验方法,确定了试件尺寸、侵蚀溶液及其浓度、宏观和微观测试指标等.采用硫酸根离子浓度测试方法得到了硫酸盐侵蚀深度和硫酸根离子浓度随时间的变化和分布规律,采用同步热分析仪对混凝土硫酸盐侵蚀产物及其随时间的变化规律进行定量分析.

| Abstract: | Based on existing test methods of sulfate attack concrete,the test method of sulfate attack concrete under sub-high temperature environment was put forward,and the specimen size,the sulfate solution and concentration and the macroscopic and microcosmic index are determined.The existing measurement of sulfate-on was improved to the corrosion depth and the sulfate-ion concentration in concrete as well as their changes along with the time.The Simultaneous G-DTA / DSC-Apparatus was adopted to measure the variat... |
