高性能补偿收缩混凝土的变形性能和耐久性研究

Research on the deformation property and durability of high performance shrinkage-compensating concrete

采用复掺矿物掺合料和膨胀剂制备高性能补偿收缩混凝土,对其进行变形性能和耐久性试验,并探讨了矿物掺合料、膨胀剂、养护条件等因素改善补偿收缩混凝土性能的本质,并总结了各因素对补偿收缩混凝土干燥收缩率和抗氯离子渗透能力影响的规律。

This paper produced high performance shrinkage-compensating by using mineral admixtures and expansive agent,and made experiment on the deformation property and durability.Nature of that factors that mineral admixture,expansive agent,and curing conditions improved performance of shrinkage-compensating concrete was investigated.The rule of those factors had influence on drying shrinkage and chloride ion permeability of shrinkage-compensating concrete.
