Description

A corrosion sensor, termed a corrosion coulometer, has been developed for use on steel structures. The corrosion coulometer quantifies the corrosion occurring on a steel element due to atmospheric conditions such as dust, debris, humidity, condensation and electrolytic species. Use of inexpensive monitors to accurately assess the condition of structural systems can have a major impact on reducing the costs of maintaining the infrastructure. This paper presents results from application of corrosion monitors on weathering steel bridges, at an outdoor exposure site and under laboratory conditions. The emphasis is the quantitative relationship between coulometer and adjacent panel corrosion penetration data. More detailed discussion focusing on corrosion coulometer sensor design considerations is available [1].
