The innovation proposed in this program is a tailored composite sacrificial anode for galvanic cathodic protection systems for reinforced and prestressed concrete. This anode system can be tailored for each application to provide the desired performance characteristics by changing the composition and form of the finished composite. The composite sacrificial anode will contain all of the necessary components in a single unit, minimizing the need for special installation procedures. The focus of the program will be on development and testing of composite sacrificial anodes in aqueous alkaline solution and concrete environments for galvanic protection of reinforcing steel and prestressing wires. The effects of fabrication methods, anode composition, physical characteristics and form, and concrete chemistry, resistivity and temperature on galvanic performance will be evaluated.

该项目提出的创新是一种定制的复合牺牲阳极，用于钢筋混凝土和预应力混凝土的阴极保护系统。 该阳极系统可以针对每种应用进行定制，通过改变成品复合材料的成分和形式来提供所需的性能特征。复合牺牲阳极将在一个单元中包含所有必要的组件，从而最大限度地减少特殊安装程序的需要。 该计划的重点是在碱性水溶液和混凝土环境中开发和测试复合牺牲阳极，用于对钢筋和预应力钢丝进行电流保护。 将评估制造方法、阳极成分、物理特性和形式以及混凝土化学、电阻率和温度对电化学性能的影响。
