Electrical resistivity sensor integrated in concrete structures for the measurement of corrosion of reinforcement

摘要

Sensor electrical resistivity integrated in concrete structures for the measurement of corrosion of reinforcement, characterized by finds itself connected to the steel reinforcement the concrete (11) by grounding (5) and embedded in the concrete after concreting, consisting of a power supply (8) and a device for measuring voltage and current (9); said resistivity sensor consists of two cylindrical electrodes made of steel discs (1) and discs of insulating polymeric material (2), which are arranged alternately in fixed by a joining system between discs (6) by screwing or adhesive layers mounted on a rectangular support for fixing the electrodes (7) with a set distance between electrodes 5 cm.
