摘要:
The present invention relates to a substrate for a thin film photovoltaic module, characterized in that it is a cementitious product with average surface roughness Ra not higher than 500 nm. The invention also relates to the cementitious product as such, the thin film photovoltaic module comprising it, and a method of moulding both of them.
摘要:
A method of making a building block from clay-containing compounds, which includes employing a major amount of such clay-containing material in combination with a calciferous additive and water to cure the shape the same under the influence of controlled pressure and temperature for a pre-determined time to create building block which is characterized by a mineralogical crystalline phase. The clay-containing compound includes a mixture of fine particulate material and coarser particulate material. The product produced by the method is also disclosed.
摘要:
A hybrid magnesium cement composition formed of an A-side and a B-side. The A-side having an A1-component including a light-burn grade magnesium-containing material, and an A2-component including a non-metallic oxide salt. A B-side having a metal silicate polymer is included.
摘要:
Compositions and methods for producing a manufactured product, a method for making a liquid absorbent, and processes for disposal of flammable liquids with a flue gas desulfurization by-product. The compositions for the manufactured products combine a binder and the by-product. The composition contains a greater percentage by weight of the by-product than the binder. The methods for producing manufactured products include dewatering the gypsum-depleted waste stream to reduce a water content, and forming the manufactured product. The method for making a liquid absorbent includes dewatering, granulating, drying, heating, and packaging a granulated gypsum-depleted composition as the liquid absorbent. The processes for disposal of flammable liquids include distributing a by-product into contact with flammable liquid, absorbing the liquid, transporting, and igniting the flammable liquid. The artificial soils are a combination of by-product and animal waste.
摘要:
The present invention describes a fire resistant building material composition, useful for example as a fire door core and to a method of making this composition. The building material of the present invention is prepared from an aqueous mixture of predominately expanded perlite, a small amount of a binder component consisting essentially of calcined gypsum and an organic binder, and optionally a fibrous reinforcement.
摘要:
A cementitious compostion for high density, low porosity sheet-form building materials having solid surfaces is comprised of cement, pozzolans, and a high percentage of fine and/or coarse glass aggregate.

This invention pertains to a method for remediating, detoxifying and containing various types of asbestos fibers and asbestos containing materials, such as crocidolite (and other forms of Riebeckite), and tremolite. The end-product of the method may be reclaimed or recycled as useable surfacing, structural and decorative materials. In some embodiments of the invention some end-products of the process may be used as a synthetic gemstone, counter-surfacing material cutting tool, resin for manufacture of furniture products, while others may be used to reclaim natural sand. In one embodiment of this invention crocidolite or other forms of reibeckite or tremolite asbestos debris in loose form or as a component of asbestos cement or other asbestos containing products is converted to a form of engineered quartz, yielding as a synthetic form of the gemstone Tiger's Eye or Hawk's eye. This end-product bears unique and enhanced aesthetic qualities over other types of engineered quartz, called chatoyancy (an optical effect that arises either from the fibrous structure of a material or from fibrous inclusions or cavities and is sometimes likened to the sheen off a spool of silk). The end product therefore achieves luminous more natural-looking effect, while retaining the other desirable features of engineered quartz, such as strength, imperviousness to heat, and resistance to acids and microbial contamination, and reduces the need for the addition of decorative resinous materials which diminish the endurance features of the material.
摘要:
The present invention provides a technique for prolonging the working time and setting time of a calcium sulfate hemihydrate paste by mixing calcium sulfate hemihydrate powder with an aqueous solution containing phosphate ions, so that the paste is suitable for operation and the resultant hardened calcium sulfate dihydrate block from the paste has an improved mechanical strength.
