Method for Assessment of Corrosion Activity in Reinforced Concrete.

Abstract

The probe is a nondestructive testing device for locating and measuring corrosion activity in reinforcement concrete structures by direct detection of electrochemical current flow. The device consists of a surface probe valved to present alternative measurement paths when measuring the probe potential with respect to a remote reference electrode, allowing the measurement of IR drops associated with corrosion of reinforcement 'rebar'. By grid surveys of concrete structures, areas suffering internal corrosion (the primary cause of marine concrete deterioration) can be located and the level of corrosion activity determined.
