<p><P>PROBLEM TO BE SOLVED: To provide a hydraulic cured object effective as an artificial fish shelter effective for permitting adhesive organisms to adhere, and its manufacturing method. <P>SOLUTION: The hydraulic cured object 1 is obtained by adding ground shells, ground metal slag, clinker ash (molten slag), a ground waste magnetic tape, carbon fibers, charcoal, a ground waste fishing net, silasu, ground FRP ship ground pieces and the like to a hydraulic curable material 11, which is a matrix comprising a mixture of a fine powder such as coal ash or the like, a curable material such as cement or the like and seawater/water, as aggregate 12 so as to protrude a part of the aggregate 12 from the surface of the matrix. When the hydraulic curable material 11 is sedimented in the sea or water to be constructed as a fish shelter of fishes and shellfishes, the small vortex or convection region of seawater or a change in the flow velocity of seawater becomes a various state by the projections due to the aggregate 12 and the hydraulic curable material 11 becomes high in the deposition probability of eggs or zoospores of small adhesive organisms to a substrate to become the suitable artificial fish shelter. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
