Özet

It is estimated that approximately 0.5-1 million tons of boron waste is generated annually

in Turkey. Most of these wastes are concentrated in Kırka (Eskişehir), Bandırma

(Balıkesir) and Bigadiç (Balıkesir) plants. Disposal of these wastes is an important

environmental problem. In this study, the usability of colemanite concentrator waste

from Kütahya-Emet Eti Maden Company as cement and concrete admixture was

investigated by experiments on concrete specimens. The strengths of colemanite

concentrator waste at 5%, 10%, 20% and by changing the proportions of colemanite

concentrator waste and adding fly ash with the waste into cement at 10% and 20% were

investigated. When the mechanical properties were examined, 5% colemanite waste

gave the best results in the specimens. It was also observed that it reduced the setting

time.
