Sculptured wall panel

A sorptive-filtration media for the capture of waterborne or airborne constituents. The media comprises a granular substrate and an amphoteric compound bonded to the substrate in the presence of a crystal inhibiting agent. The media can also comprise a substrate having a specific gravity of less than 1.0 and an amphoteric compound bonded to the substrate. 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.

An adsorptive-filtration media for the capture of waterborne or airborne constituents

A sorptive-filtration system for removing at least one of negatively or positively charged ions, complexes or particulates from an aqueous stream. The system includes a) flow formed substantially from at least one of rainfall-runoff or snowmelt-runoff; b) a filter containment communicating with the runoff stream such that at least part of the stream passes through the filter containment; and c) a granular filter media disposed within the filter containment, the filter media having an amphoteric material applied thereto, wherein the amphoteric material comprises a metal selected from at least one of Fe, Al, Mn, or Si.

Clarification and Sorptive-Filtration System for the Capture of Constituents and Particulate Matter in Liquids and Gases

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.

Apparatus and methods for making a masonry block with a roughened surface

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. The porous pavement material may have a hydraulic conductivity ranging from about 0.001 to about 1.0 cm/sec and may act as a storm water storage basin.

Porous pavement for water quantity and quality management

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.
