Abstract: A method of producing a fiber reinforced concrete structure of desired thickness including the steps of extruding a sheet of concrete substantially free of fibers, distributing an effective amount of reinforcing fibers on the sheet, repeating the foregoing steps until the desired thickness is approached and before the concrete sheets have set up, and extruding a further sheet of substantially fiber-free concrete over the structure resulting from the foregoing steps to achieve the desired thickness. The amount of fiber distributed over each sheet may be varied to concentrate the fiber in the areas where the greatest stress concentration is expected. Also disclosed is an apparatus for performing the method.
