【摘要】 通过开展硫酸盐干湿循环侵蚀环境对五种强度高性能混凝土的侵蚀试验,以抗压强度、电通量、硫酸根离子浓度为相关测试指标,测试经过不同干湿循环次数后混凝土指标的变化情况,研究硫酸盐干湿循环对高性能混凝土的侵蚀特性,提出增强混凝土耐久性的合理建议与措施。更多还原

【Abstract】 Through erosion test on five types of high-performance concrete in sulfate wet-dry cycle environment,the changes of concrete indicators including compressive strength,electric flux,and sulfate ion concentration after different wet-dry cycles are tested to analyze the erosion characteristics of sulfate wet-dry cycle on high-performance concrete.Finally,reasonable suggestions and measures for reinforcement of concrete durability are put forward.更多还原
