| Abstract: | A new nondestructive evaluation technique for detecting corrosion of reinforced concrete structures by measurement of resistivi- ty, namely the four - point probe method of measuring resistivity is introduced. The effect of section dimensions on resistivity measurement is discussed. The correction divisor of the effect of dimensions is obtained. The calculation results quite agree with the test data. |
