The stabilization of clayey soils is one of the most challenging areas of geotechnical engineers. In shallow and deep stabilization works, the most preferred materials are lime and cement. However, marble dust (MD) and granulated blast furnace slag (GBFS), which are more economical and environmentally friendly than these materials, are not commonly used. In the present study, the effect of MD and GBFS additives on improving the geotechnical properties of low and high plasticity clays was investigated. Various percentages of MD or GBFS (5-10-15–20%) were mixed into clayey soils. A series of experiments (compaction and unconfined compression tests) were performed on soil and soil-additive mixes and then their geotechnical properties were determined. When clayey soils are amended with MD or GBFS, the optimum moisture content decreases but bulk unit weight, maximum dry density, unconfined compressive strength depending on curing time increases. The optimum additive amount was 15% MD or 10% GBFS on CL soil and 10% MD or 15% GBFS on CH soils. In addition, the highest soil improvement ratio was achieved with 15% MD on CL soils and 15% GBFS on CH soils. The test results revealed that MD and GBFS can be utilized effectively to improve clay soils.
