MEASURING DEVICE, EQUIPMENT AND METHOD FOR MONITORING THE ONSET OF CORROSION AFFECTING STEEL REINFORCEMENTS EMBEDDED IN REINFORCED CONCRETE |
摘要 |
<p>The present invention relates to a measuring device, equipment and method for measuring the electrochemical potential affecting a steel reinforcement (8, 11) embedded in concrete, to signal in good time the onset of corrosion in prestressing cables (8) or on the bars (11) of the said reinforcement (8, 11). The invention proposes a measuring device (5) having the characteristic of comprising a plurality of wire electrodes (1A, 1B, 1C, 1D), each having an active portion (2) for detecting an electrochemical potential (DeltaVi), associated for operation with a transmission means (3) in such a way as to transmit the said detected electrochemical potential (DeltaVi), in order to make a local measurement of the onset of corrosion in the said prestressed cable (8) or in the said bar (11) of the said steel reinforcement.</p> |
