Patent number: 6869987Abstract: A settable composition which can be applied by spraying to form a coating on a surface such as the walls of a mine comprises (i) a cementitious composition comprising the following components: (a) from 25 to 95% of calcium aluminate, (b) from 0 to 10% of lien and (c) from 0 to 50% of calcium sulphate, and where the sum of (b) and (c) is at least 5% the % being by weight based on the combined weight of (a), (b) and (c) and where the proportions of the components are such that the composition on hydration is capable of absorbing at least its own weight of water and (ii) an aqueous emulsion of an organic polymer, the amount of (ii) in relation to (i) being such as to provide a weight ratio of polymer, expressed as solids, to combined weight of (a), (b) and (c) of from 0.5:1 to 10:1, preferably 1:1 to 2.5:1 or (iii) a dispersible organic polymer and where the amount of dispersible polymer is such as to give a weight ratio of polymer to combined weight of (a), (b) and (c) o from 0.5:1 to 10:1, preferably 1:1 to 2.Type: GrantFiled: March 12, 2002Date of Patent: March 22, 2005Assignee: Minova International LimitedInventors: Peter Shelley Mills, David Neil Degville, Aj Rohaly

Patent number: 6867249Abstract: The present invention relates to a process for manufacturing a construction material by mixing a cementitious material, rubber bits and water. It also extends to a construction material comprising cured cementitious material and rubber bits in which the rubber bits are bonded together in a porous and permeable matrix by the cementitious material. An elastic binding material improves the physical properties of the construction material. The construction material can be cast in place or formed into blocks for transport to a construction site.Type: GrantFiled: December 12, 2002Date of Patent: March 15, 2005Inventor: Kin Man Amazon Lee

Patent number: 6861459Abstract: A dry cast article and method for making the same, wherein the dry cast article includes an oligomeric dispersant that is a reaction product of two or three moieties is provided. To make a dry cast article, hydraulic cement, water, coarse aggregate, fine aggregate, optionally a surface active agent/air entraining agent, and an oligomeric dispersant are mixed and used to form a dry cast article from the mixture.Type: GrantFiled: September 16, 2002Date of Patent: March 1, 2005Assignee: Construction Research & Technology GmbHInventors: Thomas M. Vickers, Rainer Packe-Wirth, Michael Porsch, Samy M. Shendy, Lynn E. Brower, John Pickett, Runhai Lu, Frank Danko, Jeffrey R. Bury

Patent number: 6841595Abstract: Process for the preparation of protective colloid-stabilized, emulsifier-free, aqueous dispersions based on at least two monomers selected from vinylaromatics, 1,3-dienes and/or (meth)acrylates, in the presence of assistants and, if required, further comonomers in an amount of from 0.1% by weight to 20% by weight, based on the total amount of monomers, wherein at least 10% by weight of the total amount of water are added to the reaction vessel only after the monomers have been added to the reaction vessel and the conversion is at least 40%, based on 100% of the monomers.Type: GrantFiled: July 3, 2002Date of Patent: January 11, 2005Assignee: PolymerLatex GmbH & Co. KGInventors: Davide Brizzolara, Herbert Vorholt
