摘　　要：牺牲阳极阴极保护技术由于其施工安装方便、运行管理简单、价格低廉等优点,已被业界推荐应用于受盐污染的混凝土结构修复或防护。选取3种国产传统的牺牲阳极材料,开展在砂浆试件及混凝土试件中的电化学性能试验研究,通过30 d的短期试验结果认为,在饱水条件下,3种阳极材料均满足阴极保护的要求,但在干燥条件下,只有锌阳极满足阴极保护的要求。The sacrificial anode cathodic protection has been used in the repair or protection of concrete structure,its salt contaminated, because of convenient installation, simple operation management and low price. It selects three kinds of domestic traditional sacrificial anode material, experimental study of the electrochemical properties in cement mortar specimen and concrete specimens, the test results of short - term view by 30 days, that under the condition of full water ,three kinds of the anode material all meet the requirements of ca- thodic protection, but in dry conditions, only the zinc anode meet the requirements of cathodic protection.
