| dc.description.abstract | In recent years, the construction industry has invested a lot of effort in increasing concrete 2 safety and in extending the service life of structures. Several test methods, such as water 3 penetration, surface/bulk electrical resistivity, rapid chloride permeability (RCP), and half-cell 4 potential, have been proposed to study concrete durability. This study establishes the 5 relationship between multiple durability test methods in the context of concrete repair, which 6 was rarely selected as the object for study. By means of experimental study, this study finds 7 that surface resistivity has a linear relation to bulk resistivity and a polynomial relation to water 8 permeability. No relationship can be established between concrete resistivity and compressive 9 strength, though high-strength concrete tends to have a high resistivity. RCP test results do not 10 correlate well with resistivity measurements, which requires further study to overcome its 11 heating and binding effect when measurements are being taken. | en_US |
