  • Patent number: 9903075
    Abstract: A method for placement of roller compacted concrete (RCC) on a sub-base to produce a concrete pavement, which has: (a) dosing a concrete or concrete ingredients and loading the concrete or concrete ingredients into a concrete transportation truck, (b) adding at least one pelletizing agent to the concrete and waiting from 3 to 15 minutes under constant mixing to produce a pelletized concrete and (c) discharging the pelletized concrete obtained in step (b) on the sub-base from the concrete transportation truck, rotating the drum of the concrete transportation truck.

  • Patent number: 9688579
    Abstract: A concrete mix design having a slump class from S1 to S5 or a flow class from F1 to F6 and a workability retention between 10 minutes and 120 minutes, comprising from 150 to 600 kg of cement per cubic meter of concrete, aggregates selected from the group consisting of sand, fine aggregates, coarse aggregates or combinations thereof containing between 0.5 wt. % and 75 wt. % of phyllosilicates, is characterized in that the concrete mix design includes an admixture system 1 which is based on 100% polycarboxylate ether based copolymer (PCE), the admixture system 1 comprising at least one component B1 being a PCE copolymer.

  • Publication number: 20090234046
    Abstract: The invention relates to a copolymer, said copolymer consisting of, as structural units, (i) 0.1 to 50 mole % of units derived from an ethylenically unsaturated monomer (a) having per one mole thereof 25 to 300 moles of C2-C3 oxyalkylene groups; (ii) 0.1 to 49.9 mole % of units derived from a monomer (b) of an alkyl, alkenyl or hydroxyalkyl ester of an ethylenically unsaturated mono- or di-carboxylic acid; (iii) 0.1 to 90 mole % units derived from a monomer (c) selected from the group consisting of an ethylenically unsaturated monocarboxylic acid, a salt thereof, an ethylenically unsaturated dicarboxylic acid, an anhydride thereof and a salt thereof; (iv) optionally up to 30 mole % of other monomers. Said copolymer can be used as a concrete and/or mortar admixture that allows optimal flow ability and, at the same time, can maintain a specific consistency, fluidity and workability of the concrete independently of the cement type.
