Publication number: 20150152008Abstract: The invention concerns a solid composition comprising calcium silicate hydrate and at least one water-soluble cationic (co)polymer. Additionally, a process for producing the compositions, in which an aqueous suspension of calcium silicate hydrate, preferably suitable as a setting and curing accelerator for (portland)cement-containing binder systems, is contacted with at least one cationic (co)polymer and the product is dried. Also concerned is the use as setting accelerator in preferably (portland)cement-containing building material mixtures and as grinding assistant in the production of (portland) cement. The invention further concerned building material mixtures comprising the solid compositions of the invention.Type: ApplicationFiled: April 30, 2013Publication date: June 4, 2015Inventors: Jutta Karin Langlotz, Stefan Friedrich, Christoph Hesse

Patent number: 8906986Abstract: Claimed is a cationic copolymer and also its use as an admixture agent for building product systems, especially based on calcium sulfate. The copolymers of the invention effectuate accelerated setting behavior in clay-containing as well as non-clay-containing gypsums and they enable uncurtailed water reduction performance by dispersant agents used at the same time with the copolymers. The clay fractions in the gypsum system are masked by the cationic copolymer, and so the building product mixture exhibits properties of a building product mixture not containing clay. The copolymers are used as a formulation and also together with retarders.Type: GrantFiled: November 29, 2011Date of Patent: December 9, 2014Assignee: BASF Construction Solutions GmbHInventors: Michael Schinabeck, Frank Dierschke, Manfred Bichler, Silke Flakus-Taube, Stefan Friedrich
