A heavy duty, wear, crack and spall-resistant concrete composite floor tile comprising: a concrete substrate layer containing 4 to 16 volume percent of dispersed, fine metal fibers and, a wear-resistant concrete surface layer containing about 30 to 60 volume percent of wear-resistant, metallic or in

A heavy duty, wear, crack and spall-resistant concrete composite floor tile comprising: a concrete substrate layer containing 4 to 16 volume percent of dispersed, fine metal fibers and, a wear-resistant concrete surface layer containing about 30 to 60 volume percent of wear-resistant, metallic or inorganic aggregate, or 4 to 16 volume percent fine metal fibers, said tile being further characterized in that the layers are bonded to each other by a plurality of metal fibers having one end embedded in and bonded to the substrate layer and the other end embedded in and bonded to the surface layer, and when said surface layer contains said metal fibers, said fibers are present therein in an amount greater than the amount of said fibers in said substrate layer.
