GRAPHENIC PREPARATIONS FOR CEMENT AND CONCRETE
The invention concerns a graphenic preparation and a graphene-based cementi tious composition, comprising: - a filler selected from the group consisting of calcium carbonate, silica, kaolinite and limestone; - graphene, in an amount ranging from 0.1 to 10% by weight, with respect to amount of the graphenic preparation; and - at least one cementious additive, in an amount ranging from 3 to 40% by weight, with respect to amount of the graphenic preparation selected from the group consisting of a poly-alkyl naphthalene sulfonate, a phosphoric ester of polyoxyethylenated fatty alcohols, lignin sulfonate, sulphated melamine formaldehyde resin, sodium polycarboxylate, polyacrylate ammonium salt, a phosphoric ester and an alkoxylated phosphoric ester; wherein each of the above components is in solid-dry state. Advantageously, the invention relates to a cementitious composition and a concrete comprising the graphenic preparation.
