Abstract:
The invention is directed to a corrosion inhibition system for reinforced concrete, to the use of an intercalated double layered hydroxide as corrosion inhibitor, to a process for inhibiting corrosion of reinforced concrete, and to the use of the corrosion inhibition system in reinforced concrete. In accordance with the invention, a corrosion inhibition system for concrete reinforced with a corrosion sensitive reinforcement is provided, which system comprises layered double hydroxide intercalated with a compound represented by the following formula (I): and/or protonated forms thereof, wherein Y is NH 2 or COO - R is an optionally substituted aromatic, aliphatic, or cycloaliphatic moiety having 5-18 carbon atoms.
Abstract:
Ceramic layers are often used for heat insulation in a layer system, and have a high porosity therefor. The inventive porous ceramic heat insulating layer has a particular pore size distribution such that it has a high expansion tolerance even at temperatures higher than 1200°C.
Abstract:
A flame-retardant coating composition, which includes a cross-linked thermosetting polymer, a metal hydroxide, and a blowing agent. A precursor composition for use in preparing the flame retardant-coating is also presented, wherein the precursor composition includes a cross-linked thermosetting polymer varnish, a metal hydroxide, a blowing agent, an alcohol, and water. A method for coating an article with a flame-retardant coating layer and articles incorporating the flame-retardant coating are also presented.
Abstract:
Keramische Schichten werden oft zur Wärmedämmung in einem Schichtsystem eingesetzt. Dabei weisen sie eine hohe Porosität auf. Die erfindungsgemäße poröse keramische Wärmedämmschicht weist eine besondere Verteilung in der Porengröße auf, so dass sie auch bei Temperaturen größer 1200°C eine große Dehnungstoleranz aufweist.
Abstract:
A waterborne coating composition comprising a waterborne epoxy coating with hydraulic cement, which is capable of a thin initial application. The coating composition may be made, stored and transported as a two-part composition, where each part is a pourable liquid. The waterborne epoxy composition cures under normal conditions and adheres to surfaces including masonry, concrete and metal.
Abstract:
Substantially hydrated cementitious particulates useful for delivering admixtures and additives into adhesives, coatings, paints, and other matrix compositions such as cement, concrete, masonry, mortar, fireproofing, shotcrete, and others. Preferred embodiments include intermixing at least one admixture, water, and hydratable cementitious binder to provide a substantially hydrated hardened mass and comminuting the hardened mass into particulates.
Abstract:
Composite materials of the invention, which include a gas-tight ceramic, a porous metallic support, and an interfacial zone therebetween eliminate the need for mechanical seals between two such dissimilar materials. Oxygen ion-conducting dense ceramic membranes are formed on a porous metallic alloy to provide an interfacial zone identifiable by a gradient of composition in at least one metallic element across the interfacial zone between the dense ceramic membrane and the porous support. Processes using composite materials in accordance with the invention are, for example, used for production of synthesis gas comprising carbon monoxide and molecular hydrogen, whereby the synthesis gas is, advantageously, free of deleterious and/or inert gaseous diluents such as nitrogen.
Abstract:
The present invention relates to composite materials for membrane reactors which include a gas-tight ceramic (28), a porous support (15, 16), and an interfacial zone therebetween. More particularly, this invention relates to composite materials using oxygen ion-conducting dense ceramic membranes (28) formed on a porous support (15, 16) comprising a metallic alloy to provide an interfacial zone identifiable by a gradient of composition in at least one metallic element across the interfacial zone between the dense ceramic membrane and the porous support. Processes using composite materials in accordance with the invention are, for example, used for production of synthesis gas comprising carbon monoxide and molecular hydrogen which synthesis gas is, advantageously, free of deleterious and/or inert gaseous diluents such as nitrogen.
