摘要： Method for real-time and online monitoring the freeze-thaw damage of concrete, firstly, embed pairs of gradient electrical resistance probes into surface of the monitoring concrete at the depth of 0˜50 mm, the paired gradient electrical resistance probes adopt anti-corrosion metal bar, and the buried depth gradient of different pairs of electrical resistance probes in the range of 1 mm to 20 mm, and the buried depth gradient of the pair of electrical resistance probes nearest to the surface is less than 5 mm. Transmit the impedance value of the concrete measured by the paired gradient electrical resistance probes to the monitor center for processing. Judge the spalling status of freeze-thaw damage of concrete though the abrupt change in impedance value. Real-time online monitoring of the freeze-thaw damage of concrete can be achieved by the electrical resistance probes and monitoring center of this invention.
