Abstract

Stabilization, which is defined as the improvement of the geotechnical properties of clayey soils by using additives with pozzolanic properties, is highly preferred today because it is easy to apply, economical and many of them are environmentally friendly. As a result of the textural changes that occur after successful stabilization by adding different pozzolans to the clayey soils, the optimum water content value, which is called the compaction parameters of the soil, increases, while the maximum dry unit weight decreases. In this study, the effects of additives used in different types and ratios on the compaction parameters of high plasticity bentonite were investigated. For this purpose, samples with additives using slaked lime, fly ash, acidic and basic tuffs in different proportions were prepared and Standard Proctor tests were carried out on these samples. According to the results obtained from the studies, the best results were obtained in the case of using only one additive material, in the sample with 5% acidic tuff and in the sample with 10% slaked lime. In the examples where two types of additives were used together, the best results were obtained in the example where 10% acidic tuff and slaked lime were used together. The results obtained from this study show that the best results are obtained in compaction parameters, especially when slaked lime and acidic tuff additive are used together.
