  • Photocatalytic granular mixture for mortar and concrete and its use
    Patent number: 7556683
    Abstract: The photocatalytic granular mixture for mortar and concrete includes a photocatalyst in the form of at least two granular classes with different B.E.T. specific surfaces. It has a photocatalytic activity greater than that of a monodisperse photocatalyst with a single range of B.E.T. specific surface, and thus permits, in association with a conventional hydraulic binder, to obtain construction and repair materials whose aptitude for self cleaning, for the reduction of odors, and for the depollution of ambient air, is considerably improved.
    Type: Grant
    Filed: October 3, 2007
    Date of Patent: July 7, 2009
    Assignee: Ciments Francais
    Inventors: Laurent Bonafous, Luigi Cassar, Pierre Cassat, Pierre Colombet, Francine Colombet, legal representative, Laurent Guillot
