EFFECT OF AMBIENT TEMPERATURE ON CORROSION OF REINFORCEMENT IN REINFORCED CONCRETE STRUCTURES
-
摘要: 通过对钢筋腐蚀机理及其影响因素的分析,充分利用宏观现象与微观机理之间的关系,采用阴极、阳极控制理论,设计出两个试验装置,利用腐蚀电流与腐蚀速度之间的关系,观测温度对钢筋腐蚀速度的影响。Abstract: Through the analysis of the corrosion mechanism of reinforcement and its influencing factors, using the relation between the macroscopical phenomenon and micro mechanism and the theory of anodic control/cathodic control, two experimental devices were designed.Through the relationship of the corrosion current and the corrosion rate, the effect of ambient temperature on the corrosion rate of the reinforcement can be got.
