摘要:
基于钢筋锈蚀的机理,综合考虑影响钢筋锈蚀的各种主要因素,提出钢筋初锈时间的概念,建立相应的计算模型 .经实例验证,该模型可行、有效,计算结果能反映实际工程情况 .结果有利预测混凝土中钢筋的初锈时间,以便及时对混凝土结构进行健康诊断、防止耐久性失效
Abstract:
Based on the mechanism of corrosion of reinforcing bar, the authors consider chlorion corrosion and some other factors influencing corrosion of reinforcing bar; and initiate for the first time the concept of initial corrosion time; and establish computation model correspondingly. The model is verified by example to be workable and efficacious, the reckoning reflects actual engineering situation. This is of important significance for calculating initial corrosion time of reinforcing bar in concrete, for timely examining the health of concrete structure, and for preventing ineffectiveness of its durability.
