Abstract:
Novel hydrophobic composites, particularly hydrophobic particulates and free-flowing hydrophobic aggregates and methods utilizing same are disclosed.
Abstract:
Low density additives and methods of making said additives for composite materials are provided. The low density additives have at least a partial or complete water repellant property that reduces moisture migration, absorption, and retention within a composite material in which it is incorporated into. Active sites are engineered onto the surface of the low density additives to enhance bonding of the additives within a composite matrix. Reduced water movement and enhanced bonding lead to an increased strength and durability performance for a composite material comprising such additives. Composite materials incorporating one or more engineered low density additives as also provided, such composite materials having enhanced strength and durability. Such composite materials may be made from a Hatschek process. The composite materials may be further used as interior and exterior building products.

Abstract:
A method of manufacturing a finished product from a length of a lignocellulosic material, such as a length of solid wood or chip board, includes the steps of impregnating the length of lignocellulosic material through its depth with an impregnating composition consisting of a mineral oil, a non-aqueous solvent for the mineral oil such as dichloromethane or super critical carbon dioxide, and a thermosetting resin and, if necessary, a catalyst therefor dissolved in the mineral oil and solvent. Thereafter, the non-aqueous solvent is removed and the product is subjected to an elevated temperature to polymerise the thermosetting resin to form the finished product.
Abstract:
The use of oil-in-water-type emulsions of fatty acids (C12 to C18) and/or carboxylic acid waxes, with the possible addition of paraffin, with a solid body melting point between 40 and 80 DEG C with the use of non-ionogenic emulsifiers, possibly partly neutralised with lye, amine or ammonia, as an additive in the production of hydrocarbon-absorbent concretes or concrete blocks, and a process for producing hydrocarbon-absorbent or filtering and ecologically decomposing concrete block, in which a light aggregate (S4) for the concrete of the block together with a colouring additive (S5) is hydrophobised in an initial mixing process (M1) with an oil-in-water-type emulsion before being mixed with the customary aggregats for the production of concrete, especially premixed hydrophobic cement glue (S3 + water) and, in a further stage, cast in a mould, whereupon it is vibrated under pressure and shaped to provide a concrete adsorption block or plate.
Abstract:
A glass mat includes an assembly of glass fibers, a binder composition and an asphaltic coating. The binder composition includes an organic resin and an adhesion promoter. The glass mat has an at least 2% increase in tear strength as measured using the methods specified in ASTM D3462, compared to an asphaltic coated glass mat having a binder composition without the adhesion promoter. Further provided is an asphalt roofing product including the glass mat and a method of increasing tear strength in an asphalt roofing product.

Abstract:
A sand lime shaped product including wax mixed with sand and lime formed into a shaped product having a density of at least 200 kg/m3. A method for making a sand lime shaped product is also disclosed, including mixing wax with sand and lime to form a mixture; and forming the mixture into a shaped product.
Abstract translation:砂石灰成型产品包括与砂和石灰混合的蜡,其形成密度至少为200kg / m 3的成形产品。 还公开了一种制备沙石成型产品的方法,包括将蜡与砂和石灰混合以形成混合物; 并将该混合物形成成型产品。
Abstract:
A binary mix which provides a cementitius building material, one part of the mix being a hydraulic cement containing wet fraction capable in time of first setting and then curing while the other component of the binary mix is an aggregate fraction made up primarily of a wood material which has been coated by a substantially insoluble material. The coating is preferably applied by a pre-mixing process when the coating material is water and/or organic solvent borne. The coating is allowed to dry before the binary mixing and in use provides a substantial barrier to the movement (i) of leachate from the woody material into the cement containing wet fraction and (ii) of water from the cement containing wet fraction into the woody material for at least 5 hours after the substantially homogeneous mixing.
