摘　　要：通过测试海砂砂浆、盐水砂浆和普通砂浆中钢筋的电化学指标,研究了海砂氯离子含量对钢筋锈蚀性能的影响、氯离子引入方式对钢筋锈蚀性能的影响等问题,得出的结论有助于研究如何预防和治理“海砂屋,”并为制定海砂应用的相关规范奠定了基础。The influence of Cl^- ion contents in sea sand on the corrosive property of steel-bar is explored by steel-bar electrochemical characteristics measurement with different situations.Moreover, Cl^- ion states are also detected through electrochemical characteristics.The experimental results provide the fundamental data to prevent or deal with the corrosion problem caused by sea sand and to make use of sea sand in the practical projects.
