<p><P>PROBLEM TO BE SOLVED: To provide a measuring method of a concrete volume resistivity and a device therefor, capable of measuring the volume resistivity of concrete which is a measuring object by an easy method without breaking the concrete, and diagnosing easiness of deterioration caused by a salt damage of the concrete from the measurement result. <P>SOLUTION: In this measuring method, two current electrodes 2A for sending an AC current to the concrete 10 which is the measuring object and two potential difference electrodes 2B for measuring an AC potential difference between each current electrode 2A are installed linearly at equal intervals, and the volume resistivity of the concrete 10 is measured. The method includes: a contact step for bringing each end of the current electrodes 2A and the potential difference electrodes 2B into contact with the concrete 10; an electrolyte solution supply step for supplying an electrolyte solution to an electrode material 3 installed on the end and having conductivity and porosity; and a measuring step for sending a current through the current electrodes 2A, and measuring the AC potential difference by the potential difference electrodes 2B. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
