Abstract: A process for producing a mineral foam having water repellent properties includes a) separately preparing a slurry of cement and an aqueous foam, wherein the cement slurry includes water, at least one water repellent agent different from organosilicon compound, and Portland cement and the aqueous foam includes a co-stabiliser; b) contacting the slurry of cement with the aqueous foam to obtain a slurry of foamed cement; and c) casting the slurry of foamed cement and leave the slurry of foamed cement to set.

Abstract: A method includes utilizing a component A selected from mineral component, sand, wood flour or combinations thereof, for reducing the thermal conductivity of a mineral foam produced by a including contacting a cement slurry and an aqueous foam, the cement composition used to prepare the cement slurry comprising the component A and Portland clinker.

Abstract: A process for the production of a mineral foam suitable for its use as refractory material includes (i) separately preparing a slurry of cement and an aqueous foam, wherein the cement slurry comprises water (W), an aluminate cement (C) and a lithium salt; (ii) contacting the slurry of cement with the aqueous foam to obtain a slurry of foamed cement; (iii) adding lithium salt during or after stage (ii); (iv) casting the slurry of foamed cement and leaving it to set.

Abstract: A method for producing a composite insulating mineral construction element includes filling the cavity of a construction element including at least one cavity delimited by at least one inner wall at least partially having a water absorption rate of more than 5 g/(m2·s) at 10 minutes according to standard NF EN 772-11 of August 2011 with a foamed cement slurry including a cement being an hydraulic binder including a proportion of at least 50% by weight of calcium oxide CaO and silicone dioxide SiO2, a metal salt selected from an aluminium, magnesium or iron salt and mixtures thereof, and a cellulose ether; and leaving the foamed cement slurry to set within the cavity resulting in the formation of a mineral foam, wherein the foamed cement slurry includes from 0.01 to 0.2% by weight of cellulose ether, relative to the weight of cement.

Abstract: An asphalt mixture includes bitumen partially or in totality proceeding from construction materials, the bitumen having been regenerated using a fatty acid ester which is obtained from esterified vegetable oil.

Abstract: An element is directed to the dry construction of lightweight walls, especially the construction of load-bearing lightweight façades or non-load-bearing lightweight façades, which do not contribute to the stability of the building. The element includes a panel based on a hydraulic binding agent and all or part of the face is coated with a polymer film obtained by polymerization under the action of radiation. The element also includes a structure, and a jointing component resistant to air transfers and thermal and hydric transfers. The element does not comprise any membranes that are resistant to air transfers and thermal and hydric transfers.

Abstract: Processes for the production of polymers by emulsion polymerization of olefinically unsaturated monomers, in which olefinically unsaturated esters corresponding to formula (I): HOOC—CH?CH—COO—(BO)z(PO)y(EO)xR1??(I) in which R1 is an alkyl group or alkenylphenol group containing 8 to 24 carbon atoms, BO is a butylene oxide unit, PO is a propylene oxide unit and EO is an ethylene oxide unit and the indices x, y and z independently of one another stand for 0 or for numbers of 1 to 50, with the proviso that at least one of the indices x, y and z is not 0, the carboxyl group of the compounds (I) being completely or partly present in neutralized form and the C?C double bond being cis- or trans-configured; are used as copolymerizable emulsifiers.
