Abstract
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.
Claims18
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 aggregate or an inorganic aggregate having a Mohs hardness of at least 7,
- said tile being further characterized in that the layers are bonded to each other by a plurality of metal fibers in said substrate layer having one end embedded in and bonded to the substrate layer and the other end embedded in and bonded to the surface layer.
A heavy duty, wear, crack and spall-resistant concrete composite floor tile comprising:
- a concrete substrate layer containing about 4 to 16 volume percent of dispersed, fine, metal fibers, and
- a wear-resistant, concrete surface layer containing about 4 to 16 volume percent metal fibers,
- said tile being further characterized in that a plurality of said metal fibers have one end embedded in and bonded to said substrate layer and the other end embedded in and bonded to said surface layer and the amount of fibers present in said surface layer is greater than the amount of fibers present in said substrate layer.
An industrial flooring comprising a horizontal array of heavy duty, wear, crack, and spall resistant concrete composite tiles, said floor tiles 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 a wear-resistant, metallic aggregate or an inorganic aggregate having a Mohs hardness of at least 7,
- 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.
An industrial flooring comprising a horizontal array of heavy duty, wear, crack and spall-resistant concrete composite tiles, said tiles comprising:
- a concrete substrate containing about 4 to 16 volume percent of dispersed, fine, metal fibers, and
- a wear-resistant, concrete surface layer containing about 4 to 16 volume percent metal fibers,
- said tile being further characterized in that said layers are bonded to each other by a plurality of metal fibers having one end embedded in and bonded to said substrated layer and the other end embedded in and bonded to said surface layer, and said fibers being present in said surface layer in an amount greater than the amount of said fibers in said substrate layer.
