    Cracked or broken ceramic tiles are not accepted as commercial products; therefore, the unsold tile waste creates vital environment problem. These wastes are used partly as raw materials in ceramic factories but mostly stored near factories. From economical point of view, it is proposed to reuse the industrial by-products and waste materials in the process; otherwise those have to be transported to landfill sites. The aim of this research is to search the use of fired ceramic tile wastes in the production of blended cements in cement industry. In this way, the reduction of the used clinker contributes to the reduction of carbon dioxide and other emissions during clinker firing. Three types of fired ceramic wastes, namely floor tile, wall tile and granite tile, were used. Firstly; the physical, chemical and mineralogical characterizations of these fired ceramic tile waste were determined. Then, the crushing and grinding test were performed in order to compare the grindability of the ceramic tile wastes and clinker. The ground powders of each waste, which have the fineness of 5% residue on 32 micron sieve, were added by 5, 10 and 15% to the ground clinker and gypsum. In experimental studies, the physical, chemical, and mechanical analysis were conducted on produced blended cements in accordance with standards. In all experiments, the produced blended cements comply with the defined product standards. The additions of wall tile waste also enhance the 2-7-28 and 90 days strength developments of produced blended cements compared to reference cement of CEM I. By contrast, the increasing amount of floor tile and granite tile waste in cement results in slight reductions in strength values compared to reference cement. Despite the decrease in strength values, they remained within the limits defined in the standards. Thus, economic and environmental problems were reduced partially by the addition of ceramic tiles. The full results of the research are illustrated in this article.
