Abstract
A fluidizing composition in the form of a liquid or in the form of a powder including at least one superplasticizer chosen from polycarboxylate ethers, characterized in that it includes from 1 to 20 parts by weight of at least one aromatic hydrocarbon sulfonic acid or one of its salts chosen from alkali salts, alkaline-earth salts or one of their mixtures, for 100 parts by weight of the superplasticizer. A method for preparing such fluidizing composition, a dry mortar incorporating the fluidizing composition, as well as plasters prepared from the dry mortar are also described.

A fluidizing composition comprising:
- at least one superplasticizer chosen from polycarboxylate ether polymers, which comprises from 1 to 20 parts by weight, of at least one aromatic hydrocarbon sulfonic acid or at least one salt of said at least one aromatic hydrocarbon sulfonic acid chosen from alkali salts, alkaline-earth salts or one of their mixtures, for 100 parts by weight of superplasticizer, said superplasticizer representing at least 40%, by weight, relative to the dry fluidizing composition total weight.
