Polycondensation product based on aromatic compounds, method for the preparation and use thereof

A process for forming a composition comprising mixing a polycondensation product with aqueous suspensions of inorganic binders including alkali-activated and/or alkali-activatable aluminosilicate binders in the composition, wherein the inorganic binders in the composition include less than 20% hydraulic cement based on the total weight of the inorganic binders, wherein said polycondensation product comprises as monomer components:

• A) at least one aryl polyoxyalkylene ether of the formula (I)
• where
• Ar is an aryl group,
• R1 and R2 each independently of one another are selected from H, methyl and ethyl,
• m is an integer from greater than or equal to 3 to 280 in the at least one aryl polyoxyalkylene ether of the formula (I) and
• R3 is selected from the group consisting of H, alkyl, aryl, aralkyl, alkaryl, phosphate, and also mixtures thereof;
• B) at least one aromatic compound selected from the group consisting of benzene-1,2-diol, benzene-1,2,3-triol, 2-hydroxybenzoic acid, 2,3-dihydroxybenzoic acid,3,4-dihydroxybenzoic acid, 3,4,5-trihydroxybenzoic acid, phthalic acid, 3-hydroxyphthalic acid, 2,3-dihydroxybenzenesulphonic acid, 3,4-dihydroxybenzenesulphonic acid, 1,2-dihydroxynaphthalene, 2,3-dihydroxynaphthalene, 1,2-dihydroxynaphthalene-5-sulphonic acid, 2,3-dihydroxynaphthalene-6-sulphonic acid, and mixtures thereof;
• C) at least one aldehyde;
• and
• D) at least one further aromatic compound, selected from the group consisting of 2-phenoxyethanol, 2-phenoxyethyl phosphate, 2-phenoxyethyl phosphonate, 2-phenoxyacetic acid, and mixtures thereof.
