摘　　要：在相同人工气候条件下,研究再生集料混凝土(取代率为50%)与普通混凝土内部钢筋锈蚀速率的时变情况,得出再生混凝土钢筋锈蚀速率时变规律,分析其机理.并探讨了掺加粉煤灰对于再生混凝土和普通混凝土内钢筋锈蚀速率时变规律的影响.Under same artificial climate condition,this paper studies time-dependent deformation condition of steel corrosion rate recycled aggregate concrete with the replacement of 50% and natural concrete.Based on that,it concludes time-dependent deformation of steel corrosion rate in recycled concrete and analyzes its mechanism.In addition,it studies mixing fly ash＇s influence on time-dependent deformation of steel corrosion rate in recycled concrete and natural concrete.

关 键 词：再生集料 混凝土 钢筋锈蚀速率 时变规律 配合比 恒定环境
