掺合料混凝土在不同硫酸盐环境中的性能分析

Property analysis of concrete with admixtures under different sulfate environment

采用试验室干湿交替快速试验的方法,通过对掺合料混凝土试块外观变化、质量损失、抗压强度的记录和微观结构的扫描。比较和分析在不同浓度和种类硫酸盐溶液中,掺合料混凝土腐蚀破坏机理;考察和研究硫酸盐浸泡溶液浓度和种类的不同,对掺合料混凝土抗腐蚀性能的影响。

By following the experimental cyclic wetting and drying measure,the concrete blocks with admixtures are tested by investigating the mass loss,the compressve strength reduction together with the changes happened on both of the appearance and microstructure.The sulfate corrosion mechanism of concrete with admixtures is analyzed by comparing the influences brought by the difference in sulphate types and concentration.Their specific influences will be outlined as well.
