ABSTRACT:
A flux composition for cement comprises mainly wollastonite. One of the compositions of the flux is wollastonite 99%, fluorite 5-15% and gypsum 30-35%. The flux is added during the preparation of the cement raw materials and comprises 1-10% of the admixture. Thus, the firing temperature firing time may be shortened, the consumption of coal may be decreased and manufacturing productivity of the cement may be improved. In addition, the compression strength and the binding strength of the cement are also improved.
