Effect of Marble Dust on Consolidation Characteristics of Clay Soils
The usage of waste materials as an additive material has became widespread, in soil stabilization. This case was positive effects on environment by means of recycling, regains to economy and reducing environmental pollutions. In this study, marble dust had been used as an additive material in clay soil. Marble dust is a waste of the marble industry and despite its recycling in various industries, there is still a significant amount of marble dust left as waste. In this study, soil specimens were sampled from different locations in the ANS campus of Afyon Kocatepe University. These specimens were mixed with waste marble dust at ratios of 5%, 10% and 15%. Geotechnical experiments were carried out on specimens. Test results shows that marble dust have affected consolidation characteristics of clay soils. Especially, swelling index and consolidation index of specimens were decreased. This decrease is important in point of swelling potential of clay soils.
