Abstract

There are many waste materials in our country as in the whole world. The variety and intensity of waste materials increase day by day. Unless these materials are recycled in different ways, they will cause negative effects on environment and thus on nature. This damage will be minimized by reusing these materials and ensuring their recycling. There have been many scientific studies conducted and still being conducted on recycling of waste materials around the world and also in Turkey. The aim of this study is to investigate the usefulness of iron and chromium slag of clay stabilization. In addition, this study was to examine the impact on the ground two waste materials in comparison. In this study, the exchange rate of the physical characteristics and strength features of the ground will be experimentally examined as a result of specific gravity test, grain size, liquid limit, plastic limit, compaction test, unconfined compressive strength test, permeability test practiced by separately adding chrome and iron slags onto a clay soil in the rates of 5, 10 and 15 % in terms of weight. As a result of this study, while improvement will take place in the physical characteristics of clays, the environmental damage of an industrial waste material will be minimized by ensuring recycling.Table 1SiO2Fe2O3Fe2O3SiO2SiO2Al2O3Fe2O3Al2O3Cr2O3Al2O3TiO2Na2OK2ONa2ONa2OP2O5P2O5TiO2Cr2O3P2O5Cr2O3TiO2As2O3Co3O4SO3SO3ZrO2K2OSO3Co3O4As2O3ZrO2Rb2ORb2OY2O3Y2O3
