Another media comprises a substrate with a specific surface area of greater than 0.1 m2/gm and an amphoteric compound bonded to the substrate. Another media includes a granular substrate and a manganese oxide amphoteric compound formed on the substrate. Also disclosed is a pavement material for the capture of waterborne constituents. The pavement material comprises a porous pavement substrate and an amphoteric compound bonded to the substrate. Also disclosed is a method for producing a porous, cementitious material. The method includes the steps of providing and thoroughly mixing cement and aggregate, mixing water with the cement and aggregate into a slurry while maintaining a water to cement ratio of less than one, initiating curing of said slurry under pressure and in the presence of steam, and continuing the curing at ambient temperature and pressure until the cementitious material is substantially dry.

Apparatus and methods are disclosed for making masonry blocks (72) with one or more surfaces having a roughened texture resembling that of a split block or natural stone. In one embodiment, a mold comprises a plurality of walls defining at least one mold cavity (68) adapted to receive block-forming material. The mold defines an opening through which a formed, uncured block may be removed from the mold. At least one wall of the mold has a plurality of projections (18) extending into the mold cavity (68) so as to contact an adjacent surface of the uncured block in the mold cavity. The projections (18) are positioned such that when the uncured block is removed from the mold, the projections texture the adjacent surface of the uncured block.

The invention discloses a bionic concrete artificial fish reef arranged on the seafloor. According to the fish reef, C40 concrete is used for pouring to form an artificial fish reef base body, the surface of the base body is covered with a protective layer which is composed of cement mortar, biological calcium carbonate and oyster shells, the biological calcium carbonate is made of eggshells, corals, seashells and fishbone and is used as an additive to be added into the cement mortar, the cement mortar mixture is smeared on the surface of the fish reef base body to form cement paste after the biological calcium carbonate and the cement mortar are evenly stirred together, and the oyster shells are inlaid in the cement paste in a convex face outward mode. According to the artificial fish reef, the environment-friendly function, the durable function and the trapping function are integrated, the cement mortar covering layer doped with the biological calcium carbonate and the coating of the oyster shells can attract marine organisms to inhabit, and thus the trapping effect of the artificial fish reef can be better achieved; compared with a traditional concrete fish reef, the artificial fish reef has good waterproof property and chloride ion resistance, surface roughness and alkalinity of the surface of the fish reef are appropriate, bionic performance is achieved, and the fish collecting effect is excellent.

Bionic concrete artificial fish reef and preparation method thereof

This invention is intended to provide a high strength porous concrete structure which is preferably applied to a water permeable pavement, a draining pavement, a sound insulating board, a sound-proofing barrier, a sound absorbing block for acoustic, a block for plants, a riverbed block, a water purifying matrix, a gas absorbing matrix, a decorative board for building, a fish reef, a block for fish reef or a block for breeding algae and to provide a method of manufacturing the high strength porous concrete structure. The high strength porous concrete structure 1 having an arrangement in which a plurality of lumps 2 whose configuration is rough aggregates are integrally formed with the same concrete tissue and a gap 3 formed between the lumps 2 is through to a back side 2a of the lump 2 is manufactured by putting a thermoplastic material 8 into contact with a surface of a porous concrete structure 6 using rough aggregates 10 so as to form a form 9 and placing mortar or concrete 13 which does not include rough aggregates into the form 9.

PROBLEM TO BE SOLVED: To provide a precast concrete block for an artificial fish reef, useful as a unit element for the fish reef constituting a field for proliferating algae and having an excellent alga-proliferating property by effectively using the calcareous compositions of waste marine products such as waste oyster shells. SOLUTION: This precast concrete block 1 used for an artificial fish reef and having surface shapes corresponding to materials 61 to be transferred is produced by bringing a thermoplastic material 7 into contact with the materials 61 to form a mold 72, and subsequently pouring a concrete, mortar or cement containing the calcareous composition pulverized or non-pulverized product of waste marine products such as waste oyster shells 51 into the formed mold 72. An alga-proliferating field 4 suitable for the proliferation of algae comprises a main artificial fish reef 2 using the precast concrete blocks 1 and a wave- breaking artificial fish reefs 3.

PROBLEM TO BE SOLVED: To provide a method for effectively treating marine products such as oyster shells which are conventionally treated as waste products, and to provide a useful artificial fish reef produced by the method. SOLUTION: The treatment in which forms or properties of the marine products containing calcium such as seashells, bones of fished and husks of crustacean are changed and are functioned as a fish reef are imparted thereto is performed. Furthermore, the artificial fish reef formed by the method is made to have a marine products-mixed block and a space in which lives living with feed can inhabit is formed among the plural marine products-mixed blocks or in the individual marine products-mixed block.
