Abstract

This paper describes the construction and operation of a galvanic sensor which responds to changes in the corrosion intensity of mild steel in carbonated mortars or concretes. The sensor is simple to construct and operate. It is robust and has potential for development as an inexpensive method for long- term, continuous non-destructive corrosion monitoring of steel in concrete. Its range of possible applications include laboratory and field studies of effects of environmental exposure conditions and cement matrix variables on corrosion rates of steel in reinforced concrete structures. Information derived from such investigations is needed to provide basis for service-life prediction.
