Patent ID: 8110130

Claim:
A process, comprising carrying out vibrocompaction of a formulation comprising: at least one non-cross-linked copolymer; water; at least one hydraulic binder; and a rheological additive, wherein the additive is an emulsion of the at least one non-cross-linked copolymer, wherein the copolymer comprises: a) (meth)acrylic acid; b) alkyl (meth)acrylate having 1 to 25 carbon atoms; and c) a monomer of formula R 1 —(R 2 O) m —R 3 , wherein R 1 designates a radical having an unsaturated polymerizable function, wherein the radical comprises at least one selected from the group consisting of a vinylic, an acrylic ester, a methacrylic ester, a maleic ester, an unsaturated urethane, an allylic ether, a vinylic ether, whether or not substituted, an ethylenically unsaturated amide, an ethylenically unsaturated imide, acrylamide, and methacrylamide, R 2 O designates an alkylene oxide group having 1 to 6 carbon atoms, m is an integer between 20 and 30, and R 3 designates a linear or branched alkyl chain having 28 to 33 carbon atoms, and wherein a weight ratio of the water to the hydraulic binder, E/L ratio, is higher than 0.25.
