Document Type and Number:
Japanese Patent JP6823208
Kind Code:
B2
Abstract:
This metallic structure corrosion evaluating system is provided with: a measurement terminal electrically connected to a metallic structure in concrete; a reference electrode buried in the concrete; a potentiometer which measures a potential difference between the measurement terminal and the reference electrode and outputs measurement data indicating the potential difference; a compensation unit which performs calculation processing on the measurement data by using a weighted moving average; and an analysis/evaluation unit which analyzes the measurement data, on which the calculation processing has been performed, and evaluates the state of corrosion of the metallic structure.
