Abstract:The current research goal is to develop appropriate relationships to predict results of resistivity measurements of the standard ASTM C1760 test method using test data from some other methods: impedance spectroscopy, and one-probe and four-probe methods. For this purpose, 49 concrete mixtures with a vast variety of resistivity were tested under similar conditions. The one-probe method test specimens were rectangular slabs with an edge of 300 mm (12 in.) and a height of 110 mm (4.5 in.), and the other test specimens were 100 mm (4 in.) diameter cylinders with a 200 mm (8 in.) height. The outcomes demonstrated little difference between the results of impedance spectroscopy, and one-probe and modified four-probe methods with ASTM C1760 methods. The cell constant of one-probe method, based on standard method results, has been included into the calculation in a special condition. Some relations were also derived to predict the standard method results using the other method’s results.
