  • Publication number: 20260042708
    Abstract: A process for preparing a wet concrete composition, including mixing with water: aggregate(s), a binder system, which is 400 Kg per m3 or less of the wet concrete composition, and an admixture formulation. The binder system is prepared before or during the mixing, from at least some of the different components of the binder system, taken separately and/or in premix form(s). The binder system has between 1% and 34% dry weight of lime source(s), between 5% and 75% dry weight of ground granulated blast furnace slag, between 21% and 90% dry weight of filler(s), and between 0.1% and 5% SO3 dry weight, relative to the lime source(s), slag and filler(s). The admixture formulation includes at least one water reducing polymer, optionally with a wetting agent and/or surfactant. The mixing is carried out at a water to binder system weight ratio between 0.2 and 0.4.

  • Publication number: 20250100930
    Abstract: A ready-mix concrete or mortar, or precast concrete composition has at least one aggregate (A), a binder composition (B), at least one alkali sulfate activator (C), water (D) and at least one water reducing polymer (E). The binder composition includes ground blast furnace slag and one or more optional components being at least one hydraulic binder other than slag, one or more supplementary cementitious materials, and one or more filler materials. The water reducing polymer (E) is a copolymer comprising the following monomeric units, a monomeric unit A between 0 and 40, a monomeric unit B between 25 and 95, a monomeric unit C between 5 and 50, and a monomeric unit D between 0 and 25, the values being in mol %. The ready-mix concrete or mortar, or precast concrete composition is classified in one of the classes S3, S4 and S5 according to standard NF EN 206.
