The present invention refers to low quality cover for a package using iron ore relates to, in particular water 135-145kgf/m3, cement 370-385kgf/m3, low quality iron ore 1120-1220kgf/m3, fine aggregate 680-750kgf/m3, admixture 1.8-2kgf/m3 the obtained by mixing at, pit in the abandoned to the curvature change of the coarse iron ore quality low which is not used by mixing an aggregate used instead and real estate can be conserved as the absorption and wear degree exhibits high strength and small repetitive is byproduct with an external force of the bent improved further and load. obtained.
