摘要
通过试验研究和机理分析,验证了混凝土电化学再碱化技术对恢复钢筋周围碱性环境以及腐蚀防护的有效性,得出再碱化过程中电化学作用、电渗作用以及扩散作用是同时存在的,再碱化是电化学、电渗和扩散相互结合共同作用的过程。
According to experiment and mechanism analysis, the validity of realkalization technique for resuming alkalescent condition around the steel bar in carboned concrete and corrosion prevention is tested. It can be concluded that realkalization is a result of the conjunct function of a series of processes like electrolysis, electroosmosis and diffusion, in which electrolysis, electroosmosis and diffusion are concomitant.
