摘要
模拟水利与水运工程混凝土结构在硫酸盐介质侵蚀下的工作环境,通过试验研究了自密实混凝土抗压强度和耐磨性能。利用孔结构分析法从细观方面对硫酸盐侵蚀下自密实混凝土性能变化的内在机理进行分析,发现自密实混凝土内部的孔结构得到较大改善,这使得自密实混凝土在硫酸盐侵蚀状态下具有良好的耐久性能。
By simulating the sulfate corrosion condition of concrete structure widely used in hydraulic projects and water transportation engineering, we study the compressive strength and wear-resisting property of selfcompacting concrete based on the tests. We also analyze the internal mechanism of performance changes of self- compacting concrete by pore structure analysis method. The results show that its pore structure is greatly improved. Therefore, the self-compacting concrete has good durability in sulfate erosion condition.
