Abstract

Using stone columns to support the structure constructed over weak soil strata is a widespread technique among engineers. The performance of a stone column (SC) mainly depends upon the soil in which it is installed, the material used to prepare it, the pattern, and its dimensions. This study evaluates the potential utilisation of crushed concrete debris (CCD) and recycled concrete aggregate (RCA) in the SC construction. For this purpose, a series of model tests on the square foundation supported by SC constructed in soft soil were conducted. The effect of the length of the column, the diameter of the column, and the number of columns prepared by two materials, CCD and RCA, are considered in this study. It is found that the SC prepared by RCA has a better load carrying capacity than the SC prepared by CCD. The improvement factor (IF) is determined based on the load-carrying capacity of SC made with RCA and CCD with respect to untreated soil. Test results have shown that the CCD and RCA both have the potential to be use as a construction material for SC.
