  • Patent number: 10155692
    Abstract: Disclosed are hydrophobic finish compositions and cementitious articles made with the hydrophobic finish compositions. In some embodiments, the article is a waterproof gypsum panel 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 have many uses, such as, tilebacker board in wet or dry areas of buildings, exterior weather barrier panel for use as exterior sheathing, and roof cover board having water durability and low surface absorption. The flexible and hydrophobic cementitious finish can include fly ash, film-forming polymer, silane compound (e.g., alkyl alkoxysilane), an extended flow time retention agent including either one or more carboxylic acids, salts of carboxylic acids, or mixtures thereof, and other optional additives.

  • Patent number: 9676667
    Abstract: The present invention concerns a process for oxidizing lignin at alkaline conditions. This oxidized lignin can be used as a dispersant in various end-products, for example as a renewable plasticizer in cement-containing products, such as concrete, where the ability of the oxidized lignin to endure alkaline conditions is an advantage. Further, the invention concerns a concrete mixture containing aggregate, cement, water and a plasticizer formed of oxidized lignin, and a process for producing such a concrete mixture. The oxidized lignin can be manufactured using a process, where the lignin starting material is reacted with an oxidizing agent in solution in alkaline conditions.

    Abstract: This invention relates to a new class of chemical admixtures for hydraulic cement compositions such as pastes, mortars, grouts and concretes. The cement compositions are comprised of ordinary Portland cement, blended cements, or non-Portland cements made with Supplementary Cementitious Materials. The admixtures contain complexes of metals with derivatives of hydroxycarboxylic acids, and improve properties of cement compositions, including setting, hardness, compressive strength, shrinkage, and freeze-thaw resistance. The invention discloses a method for improving the properties of hydraulic cements by adding the disclosed chemical admixtures to cement compositions, and also discloses methods of preparing said admixtures.

  • Publication number: 20130214448
    Abstract: The invention relates to an emulsion consisting of an oily phase dispersed in an aqueous phase, comprising a non-quaternary amine surfactant and an acid with a set-retarding effect as well as to a method for its preparation. Moreover, it relates to a method for surface retarding of a hydraulic composition, comprising the steps of: (a) shaping the hydraulic composition; (b) applying onto the surface of the hydraulic composition, the emulsion according to the invention, which by breaking releases the oily phase; and (c) after hardening of the hydraulic composition, removing the film formed with the non-hardened hydraulic composition surface layer.

  • Publication number: 20130180436
    Abstract: Compositions and methods for increasing grinding efficiency of cement, cement clinker, raw materials for cement, and other inorganic particles. Use of biomass-derived polyols such as diols, triols, or mixtures thereof, optionally with a conventional grinding aid, cement quality improver, and/or hexavalent chromium reducer, are believed to provide less risk of sludging when compared to glycerides obtained from fossil fuel sources.

  • Patent number: 8470907
    Abstract: An additive based on a polyalkylenimine and a sulphonated formaldehyde-containing condensate and its use as a fluid loss additive in the cementing of wells in the mineral oil and natural gas sector is claimed. Polyethylenimine, polypropylenimine and polybutylenimine are suitable as typical representatives of the polyalkylenimines and may also be derivatised. Preferred condensates are acetone/formaldehyde resins. Those additives according to the invention which are subjected to maturing, in particular by allowing to stand, prior to their use achieve a particularly low fluid loss value.
