摘　　要：在人工气候条件下,保持环境的温湿度恒定,研究掺入不同量粉煤灰后混凝土内钢筋锈蚀速率随时间而变化的情况,得出粉煤灰的掺量对钢筋锈蚀速率时变的影响规律,并对其机理进行分析。Under the condition of artificial climate, the influence of different contents of fly-ash on the regularity of time-dependent steel corrosion rate of concrete was studied with testing on keeping the environmental temperature and humidity constantly. As a result, the relationship between time-dependent steel corrosion rate and different contents of fly-ash has been obtained, and its mechanism is analysed.
