• Resumen

  • One of the finest techniques to highlight the terrain is to employ stone columns. decreasing soil stability while raising the soil's carrying capacity. In this study, recycled concrete aggregate-reinforced masonry columns were applied as the support structure. There are various techniques to fortify soft clay soils. According to the findings, soil BC significantly improved when stone columns made from recycled concrete aggregates and thoroughly reinforced with a geogrid net were used. The soil BC of the single, five, and nine columns was enhanced using stone and double columns supported by a geogrid in comparison to natural soils. The corresponding improvement rates were 5.5%, 23.3%, and 61.1%.
