Study on Production of Magnesium Oxychloride Composite Tile Using Kuancheng Iron Ore Tailings
Using Kuancheng iron ore tailings as aggregate base,magnesium oxychloride cement as gelling,the manufac-turing of composite tile was studied in this paper.Experimental results showed that the best formula is 70%, 60-mesh Kuancheng iron tailings,30%, magnesium oxychloride cement,and the best proportion of magnesium oxychloride MgO∶MgCl2·6,H2O∶H2O is 8∶1∶13;the sawdust additive is 2.5%,,and 0.2%,~0.5%, oxalic acid and ferrous sulfate were taken as additives to reduce tile weight and improve tile strength and water resistance.Iron ore tailing composite tiles can not only reduce environmental pollution,but also replace clay tiles due to their outstanding performance.
