钢筋混凝土是一种应用极其广泛的结构材料。钢筋混凝土的腐蚀行为除取决于钢筋材料及混凝土组成材料的物理化学性能、结构构造及施工质量外,主要与所处的环境有关。就环境介质而言,主要是来自外部环境,或混凝土中所含NaCl引起的盐害。本工作探讨在Ca(OH)_2饱和水溶液中不同C厂浓度及pH对钢筋的腐蚀行为,同时对混疑土中电化学参数进行了测试,进而探索混凝土中钢筋的电化学腐蚀过程。
Reinforced concrete is a very wide range of structural materials. Corrosion behavior of reinforced concrete depends not only on the physical and chemical properties, structural structure and construction quality of the reinforced materials and concrete components, but mainly on the environment. In the case of environmental media, it is mainly from the external environment or salt damage caused by NaCl contained in the concrete. This work explored the corrosion behavior of steel bars in different concentrations and pH values of Ca (OH) 2 in saturated aqueous solution. At the same time, the electrochemical parameters of concrete were tested, and then the electrochemical corrosion process of steel bars in concrete was explored.
