The useability of magnesium slag in the improvement of fine-grained soil

Due to reasons such as rapid urbanization, rapid reduction of suitable settlement areas and excessive increase in building sizes, the need for floor improvement in the construction sector has increased significantly. In these cases, one of the solutions to be applied is to work with waste materials while soil improvement studies are carried out with additives. With the use of waste materials, the environmental pollution of these materials to nature, etc. it will be provided to be cleaned a little from harmful aspects. In this study, although there are multiple additives that can be used in soil improvement, magnesium slag, which is obtained from pure magnesium production and accepted as industrial waste, is mixed with the ground in certain proportions (5-10-15-20-25) in soil improvement and its strengths are measured in laboratory condition and its usability in soil improvement was investigated. The specimens were subjected to axial compression test, compression test and consistency limits tests. According to the test results, strength increases occurred with increasing additive ratios and it is predicted that the strength can increase even more in the long term. It was observed that the most suitable additive rates in terms of strength were minimum 15%.
