Usability of magnesium slag for improvement of coarse soils

Population growth around the world leads to an increase in the need for housing. Although the solid ground to be built on is decreasing, there is a lot of research on the improvement of unsound soils. The issue of the use of wastes generated as a result of industrial developments in soil improvement is important for the world agenda. The damage these wastes cause to nature and living things is very high. In this study, the usability of magnesium slag, an industrial waste, in soil improvement was investigated. Samples were prepared by adding 5%, 10%, 15%, 20%, 25% and 30% magnesium slag to the ground according to the maximum dry unit volume weight and optimum water content found in the standard Proctor test. The prepared samples were subjected to uniaxial pressure and permeability tests after being kept for curing periods of 1, 7, 28, 56, and 112 days. According to the test results, as the additive used increases, the compressive strength increases and the permeability decreases. Therefore, the use of magnesium slag gives positive results in soil improvement. By using the waste material, both the economy can be contributed and the damage to the environment will be reduced.
