    摘要: Cellulose ethers, wherein at least a part of the hydroxyl groups of the cellulose backbone are substituted by methoxy groups and hydroxyalkoxy groups, and optionally alkoxy groups being different from methoxy groups, having an unconventional distribution of methoxy substituents at the 2-, 3- and 6-positions of the anhydroglucose units are described. Such cellulose ethers exhibit significantly higher thermoreversible gel strengths than any known hydroxyalkyl methyl celluloses of comparable viscosity and kind and level of substitution rendering them useful as additives for building compositions such as cement based tile adhesives. In particular, such cellulose ethers can be used to improve the attainable adhesion strength after heat storage conditioning and the temporal setting characteristics of a building composition.

    摘要: Fibre cement material, which contains organic fibres, is used as an additional raw material for the production of cement clinker. The cement clinker is produced in a system which comprises a cyclone tower (11) and a rotating drum kiln (15). The cyclone tower (11) comprises cyclones (1-5) and a pre-calciner unit (10) wherein fuel is combusted to feed the cyclone tower with heat. The raw clinker meal is passed through the cyclone tower to preheat it. By the combustion of the fuel in the pre-calciner unit (10) a hot zone is produced in the cyclone tower wherein the raw clinker meal is calcined. In order to be able to add larger amounts of the fibre cement material without causing a too high total organic carbon content of the exhaust gasses and/or without causing depositions of organic matter onto the inner walls of the cyclone tower (11), the organic fibre cement material is added in a dry powdered form in said hot zone, in particular in the pre-calciner unit (10) to be heated in less than 5 seconds to a temperature of at least 800° C.

    摘要: Disclosed are cementitious articles with hydrophobic finish. In some embodiments, the article is a waterproof gypsum panel that is surface reinforced with inorganic mineral fibers that face a flexible and hydrophobic cementitious finish possessing beneficial waterproofing properties. The waterproof gypsum panels of the invention are useful in many applications, such as, for example, tilebacker board in wet or dry areas of buildings, exterior weather barrier panel for use as exterior sheathing, and roof cover board having superior water durability and extremely low surface absorption. The flexible and hydrophobic cementitious finish of the invention can include Class C fly ash, film-forming polymer, silane compound (e.g., alkyl alkoxysilane), and otheroptional additives.
