Boron Enterprise Facilities are located in Kütahya-Emet, Eskişehir- Kırka and Balıkesir-Bigadiç regions in Türkiye. Waste materials containing a sum of boron (15-20%) occur during boron beneficiation with different mining procedures. Boron mine wastes are not evaluated completely in any sector. In the scope of this study, boron mine wastes from Kırka Boron Enterprise Facility were used as raw material in the production of one-part geopolymer binder by alkali fusion method. The effect of sodium hydroxide dosage (%4, %6, %8 and %10) and calcination temperature (600 °C, 650 °C and 700 °C for 4h) on compressive strength and microstructure was investigated. Test results showed that one-part geopolymer binder can be produced from boron wastes by using alkali fusion method. The highest compressive strength of 29,1 MPa was obtained by using 4% NH and calcination at 650 C for 4h. Furthermore, the formation of new crystalline phases in geopolymer binders at higher calcination temperature caused a decrease in compressive strength values. The main reaction product of the one-part geopolymer based on boron wastes is Mg and Na incorporated C-(Mg, Na)S-H structure. |
