Utulization of boron industry wastes in cement producing as an additive material

UTILIZATION OF BORON INDUSTRY WASTES IN CEMENT PRODUCING AS AN ADDITIVE MATERIAL SUMMARY Key words: Colemanite concentrator waste, tincal concentrator waste, fly ashes, bottom ashes, compressive strenght, cement mixes, XRF, SEM Although boron Industry wastes can be benefical tn terms of technology and economy for our Country, they do not utilize enough. In this work, colemanite concentrator wastes from Kütahya-Emet-Hisarcık and tincal concentrator wastes from Eskişehir-Kırka with Seyitömer thermal power plant wastes utilize in cement producing as an additive material. Thus energy saving in cement poduction and elimination of enviromental problems caused by these wastes were investigated. The effects of the additives on setting time, volume expansion, compressive strenght and grinding time of cement were studied. The physical and mechanical properties of the cement mixes were determined according to TS 24, chemical analysis were performed by XRF and volumetric methods. The chemical, physical and mechanical properties of cement mixes are suitable in accordance with related Turkish Standarts. It was found that the additives used in this study can be utilized as an additive material in producing cement. XVI
