Abstract The rapidly developing mining sector in recent years has also brought environmental problems together. At the beginning of these problems are mine process wastes produced in high quantities from mines every year. The waste material at 90% and the concentrate chromite at 10% are obtained in the chromite ore enrichment plants. This significant amount of waste creates pollution in nature visually and physically. The aim of the study is to determine the advantages of using foamed concrete as a building material, to reduce the production cost of foamed concrete, to produce alternative solutions for rehabilitation, and to eliminate environmental pollution. The chromite enrichment wastes obtained from Fethiye, Köyceğiz, Denizli and Burdur regions were used as aggregates in the production of foamed concrete. In this study, compressive strength experiments were carried out according to TS EN 1354, thermal conductivity experiments were carried out according to TS EN 12664. As a result, it has been observed that chromite waste (dunite) can be used in the production of foamed concrete under certain conditions. Keywords Chromite . Waste material . Dunite . Aggregate .

Introduction Chromium is a metal that is not very old and has been explored in 1797, but it has begun to be used in the early twentieth century (Daş et al. 2012). There are significant amounts of mine enrichment waste in the chrome quarries. These wastes are stored idle, the plant occupies large areas and creates pollution in nature visually and physically (Hacızade et al. 2005). Today, with the acceleration of industrial developments, parallel to increasing industrial activities and population growth, the need for raw materials after consumption of natural resources is increasing day by day. Due to the limited natural raw material reserves, the increasing amount of solid

wastes is an alternative raw material (Mirdali and İşler 2008). All the wastes generated after the production, as well as the loss of raw materials and products, the storage, transportation, and disposal of these wastes also constitute serious costs and problems in terms of operation. For this reason, the use of waste and by-products in all industrial establishments has been of interest to researchers over the last few years (Topateş et al. 2005; Şölenay and Çetiz 2005; Mirdali and Çetin 2005; Yılmaz and Toplan 2004; Oyman and Özkan 2005). The reason why the recycling of waste materials is so up-to-
