  • Method for improving the mechanical strength of cement matrices, and cement matrices produced thereby
    Patent number: 6752866
    Abstract: The mechanical property known as “strength at young ages” of cement matrices or hydraulic binders may be significantly improved by adding dispersions of mineral fillers and dispersing agents. The dispersing agents of the present invention comprise copolymers prepared by the radical copolymerization of at least one alkoxy-, aryloxy-, alkylaryloxy- or arylalkyloxy-polyalkylene glycol ethylenic urethane monomer with at least one anionic monomer and at least one non-ionic monomer, and optionally, an alkoxy-, aryloxy-, alkylaryloxy- or arylalkyloxy-polyalkylene glycol acrylate or methacrylate or an alkyloxy-, aryloxy-, alkylaryloxy- or arylalkyloxy-polyalkylene glycol allyl ether, and/or a crosslinking agent.
    Type: Grant
    Filed: October 25, 2001
    Date of Patent: June 22, 2004
    Assignee: Coatex, S.A.S.
    Inventors: Pascal Gonnon, Yves Kensicher, Christian Jacquemet

  • Method for improving the mechanical strength, particularly the strength “at the young ages” of cement matrices, and the cement matrices obtained thereby
    Patent number: 6713553
    Abstract: Cements or hydraulic binders may be prepared by adding an aqueous suspension comprising a ground mineral filler and at least one grinding aid agent to a cement or hydraulic binder. The resulting cement or hydraulic binder has very appreciably improved mechanical properties, particularly the property of “strength at young ages.” The grinding aid agent may be a natural or synthetic homopolymer and/or copolymer.
