PREDICTION METHOD FOR REINFORCEMENT CORROSION, AND MONITORING SYSTEM FOR REINFORCEMENT CORROSION

摘要

PROBLEM TO BE SOLVED: To provide a prediction method for corrosion in a reinforcement and a monitoring system for the corrosion in the reinforcement, capable of providing highly precise prediction, by installing all the time a sensor in an original position, and by using information monitored and collected in an optional period or interval.;SOLUTION: The reinforcement 4 embedded in a member 2 is classified into a plurality of reinforcement elements 27, and a sensor box 5 is buried in concrete 6 to store a collation electrode and a counter electrode 7, a concrete ohmmeter 9, and a concrete thermometer 11. A computer 19 controls a corrosion monitor 17, and a switching device 15, and an electrochemical property or the like is measured using sensors or the like in a sensor box 5. The prediction method measures the presence of the corrosion in the reinforcement 4, a time until a chloride ion content in the member 2 reaches a prescribed amount in a position of the reinforcement 4, a time until the member is neutralized in the reinforcement position, and a time until a corrosion amount of the reinforcement 4 reaches a prescribed amount, using the electrochemical property and a data as to peripheral environment of the member 2.;COPYRIGHT: (C)2007,JPO&INPIT
