  • 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.
    Type: Grant

  • 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.
