IExamining the impact of steelmaking slag on stabilizing materials in road sub-bases: A case study of Khuzestan Steel slag and soils from the Ghaizanieh and Suyse regions of Ahvaz
Steel slag is widely used worldwide in various industries including civil engineering and executive projects. Steelmaking slag is a side product in the iron production process and constitutes about ten to fifteen percent of iron smelting output and is still considered waste material. The use of this product has environmental value as well.This research examines the use of steelmaking slag from Khuzestan Steel Company for soil stabilization. Fine-grained soils from Ghizaniyeh and Suiseh in Ahvaz were analyzed by mixing various weight percentages of the slag and conducting tests on soil grading, compaction, and the California Bearing Ratio (CBR). Results indicated that the engineering properties of pure slag outperform those of the soil, enhancing both soil compaction and CBR values under saturated and dry conditions. Additionally, combining slag with clay soil significantly increases its bearing capacity, making it suitable for road embankments. The saturated CBR value for the Ghaizanieh soil (sandy clay) is 20, and a mix of 80% by weight of this soil with 20% coarse slag increases the saturated CBR value to 34. On the other hand, the saturated CBR value for the Suyse soil (low-plasticity clay) is 7, and a mix of 80% by weight of this soil with 20% fine slag increases the saturated CBR value to 30. Using the slag by-product of steel factories (slag) is beneficial from an environmental point of view.
