Abstract

The design of a microinstrument for corrosion monitoring in reinforced concrete is presented and the performance of the prototype device discussed. Sensors for the measurement of corrosion rate, corrosion potential, chloride concentration, and concrete conductivity have been developed and tested inside of model concrete slabs. The tests include electrochemical chloride driving as a method for test acceleration and wet/dry cycling. The corrosion rate and conductivity sensors perform very well, as do all aspects of the electronics. Work continues on the chloride sensor and reference electrode.
