  • Process to inert non-swelling clays
    Patent number: 10011531
    Abstract: A process to inert non-swelling clays in at least one mineral component intended for the preparation of a hydraulic composition, including the addition, to the hydraulic composition, to the mineral component or to one of the other constituents of the hydraulic composition, of an organic molecule having a cationic charge density strictly less than 0.5 meq/g and including at least two atoms each being capable of forming at least one hydrogen bond.

  • Fast hydraulic binder for parts and constructions made of concrete containing a calcium salt
    Patent number: 8992680
    Abstract: A fast hydraulic binder comprising cement, at least one first superplasticizer, a calcium salt, and at least one second superplasticizer different from the first superplasticizer and comprising a main chain and pendant groups connected to the main chain adapted so as to separate from the main chain in a basic medium, wherein the result is that the second plasticizer has a fluidifying action which increases at least temporarily over time in a basic medium.

  • PLASTICIZING MIXTURE FOR A HYDRAULIC COMPOSITION
    Publication number: 20140323614
    Abstract: A mixture for a hydraulic composition, including an inerting agent for at least partially neutralizing the harmful effects of impurities in a hydraulic composition on the workability of the hydraulic composition; a first superplasticizer different from the inerting agent; and a second superplasticizer different from the first superplasticizer and the inerting agent and having a maximum plasticizing action at 20° C. developing after the peak of the plasticizing action at 20° C. of the first superplasticizer.

  • Admixture for hydraulic binder
    Patent number: 8729160
    Abstract: A method includes adding at least one copolymer or a salt thereof acting as a plasticizer, blocking agent, or both a plasticizer and a blocking agent, to a calcium sulphate-based hydraulic binder. The copolymer includes an acrylic acid or a poly(oxy)alkylene copolymer.

  • Protection of a dispersing agent during a grinding operation
    Patent number: 8629202
    Abstract: A method includes using a composition in the production of cement, the composition including at least one dispersing agent and at least one sacrificial molecule to partially or totally retain the properties of the dispersing agent; being either in the form of a liquid solution, or an emulsion or a suspension; the quantity of the sacrificial molecule in the composition representing at least 5% by mass of the mass of dispersing agent; and being introduced before or during the grinding of the clinker.

  • Viscosity-reducing super-plasticising copolymers
    Patent number: 8563631
    Abstract: The invention mainly relates to the use of a (co)polymer having a main chain essentially consisting of (meth)acrylic units and polyoxyalkylated side-chains containing statistically-distributed hydrophobic units as an adjuvant for lowering the viscosity of hydraulic compositions.
