Title:
CHLORIDE ION SENSOR AND CHLORIDE ION CONCENTRATION MEASUREMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2020/079866
Kind Code:
A1
Abstract:
The present invention aims to provide a chloride ion sensor capable of long-term monitoring and a chloride ion concentration measurement method. This chloride ion sensor measures the chloride ion concentration in a concrete structure and comprises: at least one pair of electrodes arranged, spaced apart, on the surface of the concrete structure; and a measurement unit that measures impedance in a state in which an AC current is flowing between the at least one pair of electrodes. The at least one pair of electrodes has a hot-melt electrode including a hot-melt resin having a conductive filler dispersed therein.
