摘要
海洋环境导致钢筋腐蚀而使混凝土结构发生早期损坏是建筑工程中要考虑的重要问题.该研究模拟三种不同的侵蚀环境——海洋大气环境、海洋潮汐环境和海洋水下环境,采用硝酸银滴定法测定不同时期混凝土内部各个深度的氯离子含量,找出不同环境对氯离子在混凝土内部传输速率的影响原因.
Under sea environment,concrete structures are apt to develop early damage as a result of steel erosion,which is a significant issue of consideration in construction engineering.This study will simulate three different sea chlorine conditions-sea atmosphere environment,tide environment,underwater environment.Through measuring the Cl-content of the samples at different time by the chemic method,the influence of different environments on Cl-transmission speed in concrete can be found.
