QUALITY CONTROL ON THE COMPRESSIVE STRENGTH OF THE DEEP MIXING SOIL USING THE ELECTRICAL RESISTIVITY METHOD

Abstract

The controls of quality in the deep mixing stabilized soil methods are normally applied after the conclusion of construction, and depending on the results of tests, it is necessary to re-execution. In this study, it was examined the applicability of quality control methods on the compressive strength of deep mixing stabilized column by electrical resistivity method, comparing the resistivity ratio of 28th and third day age (ρ₂₈/ρ₃) of field column with the laboratory tests. In addition, by resistivity of 28th day age (ρ₂₈) of the column and the laboratory, is possible to estimate the compressive strength of improved column.
