Abstract (en)

[origin: WO2008141844A1] The invention relates to a dispersion comprising inorganic particles, water, and at least one water-soluble polymer. The water-soluble polymer comprises repeating units which are derived from monomers with at least one quaternary ammonium group, repeating groups which are derived from monomers with at least one carboxy group, and repeating units which are derived from polyalkoxyalkylene group-containing ester monomers with a number average molecular weight ranging from 3000 g/mol to 10,000 g/mol. The present dispersion can be used for the production of concrete in particular and can be processed over a very long period of time.
