Experimental Study on the Performances of Cement Stabilized Iron Ore Tailing Gravel in Highway Application

Abstract:

Iron ore tailings as a kind of waste products after ore dressing is one of the major industrial solid wastes. Iron ore tailings not only cover huge land and pollute environment, but also give rise to security risks. The comprehensive utilization of iron ore tailings need to be studied systematically. According to the method in Test Methods of Materials Stabilized with Inorganic Binders for Highway Engineering, the technical performances of cement stabilized iron ore tailing gravel in highway application were studied by systemic experiments in this paper. These include the strength, modulus, and frost resistance property, water stability. And the influencing factors of the mixture strength were analyzed, too. The results show that the mixture of cement stabilized iron ore tailing gravel has higher strength and modulus, good frost resistance property and water stability. The technical performances of cement stabilized iron tailing gravel conform to the current specification, so it can be used as sub-base course or base course material.
