Stabilization of Expansive Clay Soils Using Rock Cutting Waste Powder an‎d Lime

زمين شناسي

The present study aims to investigate the stabilization of expansive clay soils using stone-cutting waste powder an‎d lime. Expansive clay soils are among the most critical geotechnical materials due to their volumetric changes caused by moisture variation, which often lead to uneven settlement, cracking, an‎d reduction in structural stability. In this research, stone-cutting waste powder, a pozzolanic material rich in silica an‎d alumina, was utilized independently an‎d in combination with lime to enhance the engineering behavior of the soil. A series of laboratory tests, including Atterberglimits, compaction, swelling, an‎d unconfined compressive strength, were conducted to eva‎luate the influence of different additive ratios on the physical an‎d mechanical characteristics of the soil. The findings demonstrate that using a combined mixture of stone waste powder an‎d lime significantly reduces the soil’s plasticity an‎d swelling potential while improving its compressive strength an‎d volumetric stability. These results indicate that this combination not only enhances the geotechnical performance of expansive clay soils but also providesa sustainable an‎d economical approach by utilizing industrial waste materials, making it suitable for environmentally consci ous civil engineering applications.
