Improving the physical properties of soil using industrial waste has always been of interest to researchers And it becomes more important when Accumulation of huge volume of borrowed Soil resulting from the development of Civil projects Due to improper engineering characteristics For reuse in Civil projects Cause a lot of problems. On the other hand Given that Iran is one of the hubs of steel production and Huge volumes of steel furnace slag are produced and accumulated annually in this country, It is necessary for the optimal recycling of this waste Conduct comprehensive research in various fields of science and technology. One of the goals for the optimal use of this waste, Their use is in soil improvement for use in road construction. The present study is based on the improvement of accumulated fine-grained soil in Mobarakeh Steel area Using processed steel slag in the size of 0 to 25 mm , Has been studied For use in road construction. Engineering properties of loan soil in Mobarakeh Steel Plant (Saba area), Includes Liquid Limit and Plasticity Index , classification and seive size, After sampling from different parts, Preparation and testing in the laboratory Was initially examined According to the specifications of road building materials, Soil unsuitable for use in road construction was identified. Eventually, by performing step by step experiments, Soil engineering properties were modified using different percentages of steel slag And achieve a suitable mixture for use in road construction. Also compare the geotechnical properties of soil samples to the samples of soil and slag mixture obtained Showed that these properties improved significantly by increasing the percentage of slag.
