  • Patent number: 4832746
    Abstract: A novel cured extruded article of a metal fiber-reinforced hydraulic material is provided, wherein protrusion of the metal fibers at the extruded surfaces thereof is substantially prevented. The cured extruded article is produced by extruding a blend mixture comprising an inorganic hydraulic material, water, a reinforcing amount of metal fibers having a specified sectional area and a specified length, and a protrusion-preventing amount of non-metal fibers having a specified length into an article, and then curing the resulting article. The extruded article can be glazed by applying a glazing agent onto a desired surface thereof, heating it to a high temperature up to 1000.degree. C., and then hydrating it.
