Patent number: 8846784Abstract: Additives for application in construction chemistry are proposed comprising an organic and/or inorganic core component A) with rheology-enhancing properties and a shell component B) applied to the same by virtue of physical and/or chemical interactions which acts as a coating. Component A) should be a of water-soluble and/or water-swellable and/or water-absorbable compound of the non-cellulose type with viscosity-enhancing properties in the final application. The shell component B) should preferably be a film-forming polymer which is able to release component A) during the application in construction chemistry in a retarded manner such as for example polyvinyl alcohol, polyvinyl acetate and polyethylene glycol. Component B) can be composed of several layers and comprises at least one reactive layer.Type: GrantFiled: August 10, 2006Date of Patent: September 30, 2014Assignee: Construction Research & Technology GmbHInventors: Peter Gäberlein, Michael Schinabeck, Stefan Friedrich, Uwe Holland, Michael Eberwein, Patrick Weiss, Manfred Schuhbeck

Patent number: 8709534Abstract: A formwork release composition containing formwork release oil, which contains a hydrophobic metal oxide and/or metal sulphide component is disclosed. Photocatalytically active compounds, such as particular semiconductors and in particular TiO2, are particularly suitable. The invention also concerns the use of the formwork release composition for producing exposed concrete. The concrete and mortar products thus produced are characterized by a homogeneous surface with self-cleaning properties that gives an enhanced resistance against weathering and a much longer lasting brilliance and whiteness.Type: GrantFiled: May 14, 2009Date of Patent: April 29, 2014Assignee: Construction Research & Technology GmbHInventors: Andreas Eisenreich, Sergi Vilches, Andres Fernandez, Josep Gatell, Uwe Holland

Publication number: 20110139037Abstract: A delayed action powdery building compound is provided, consisting of a reactive support material and a liquid polymer component applied to the support material. The inventive compound can contain the support material in the form of hydraulic (latent) binder, inorganic additives and/or organic components, and the polymer component for example in the form of polyvinyl alcohols, polyvinyl acetates and MPS-based polymers. The component makes it possible to obtain the delayed liberation of the support material in an aqueous building chemical mixture as a result of a time-depending separation of the polymer component from said support material. The powdery building compound also makes it possible to carry out a time-controlled hardening of hydratable building material mixtures and to obtain a time-controlled internal drying of aqueous dispersion-based materials.Type: ApplicationFiled: October 5, 2010Publication date: June 16, 2011Applicant: CONSTRUCTION RESEARCH & TECHNOLOGY GMBHInventors: Uwe Holland, Matthias Degenkolb, Joachim Riedmiller, Peter Gäberlein, Werner Stohr, Thomas Pfeuffer, Christian Huber

Patent number: 7772300Abstract: A polymeric composition consisting of water-soluble or water-swellable copolymers containing sulfo groups and nonionic polysaccharide derivatives, such as methylcellulose (MC), hydroxyethylcellulose (HEC), hydroxypropylcellulose (HPC), methylhydroxyethylcellulose (MHEC), methylhydroxypropylcellulose (MHPC) and welan gum or diutan gum, and the use thereof as an additive in aqueous construction systems based on hydraulic binders, such as cement, lime, gypsum or anhydrite, is described. The composition can also be used in water-based paint and coating systems. The composition according to the invention exhibits a synergistic improvement of the properties and, when used in relatively small amounts, constitutes highly effective water retention agents in such construction and paint systems, which also achieve outstanding air pore stability and tack.Type: GrantFiled: March 16, 2005Date of Patent: August 10, 2010Assignee: Construction Research & Technology GmbHInventors: Michael Schinabeck, Stefan Friedrich, Uwe Holland, Peter Gâberlein, Manfred Schuhbeck
