Abstract: A fiber reinforced inorganic hardened body comprises an inorganic hardened material and a fiber reinforcing material, wherein the fiber reinforcing material has a water permeability of from 5 to 27 l/min. and a volume reduction rate of at most 10%.

Abstract: Fiber reinforced cement is continuously prepared by forming a conveyor by connecting a plurality of suction boxes each having a perforated plate, contacting the perforated plates of the suction boxes with a filter cloth and moving the suction boxes with the filter cloth at a synchronous speed, feeding a cementitious slurry and a fiber on the filter cloth, removing excess water by suction from the cementitious slurry through a suction trough connected to a suction device, and releasing the suction on the suction boxes to separate the filter cloth from the perforated plates of the suction boxes.

Abstract: An apparatus for continuous liquid-solid separation has suction boxes which respectively have a suction hole on a rear surface and a perforated surface at a front surface and said suction boxes being connected in series to form a conveyor and said suction holes being connected to a suction trough so as to give the sucking condition of the suction boxes in the zone of the suction trough wherein a filter cloth is contacted with the perforated surfaces of the suction boxes and is held by side plates which can be closed and opened at both sides of the suction boxes and the filter cloth and the suction boxes are moved at the synchronized velocity under suction.
