Abstract: Cement-based compositions comprising per 100 parts by weight of cement from 1 to 500 parts by weight of a polymer built up froma) 30-99.5% by weight of at least one alkyl ester of (meth)acrylic acid,b) 0-70% by weight of at least one vinylaromatic,c) 0.5-10% by weight of at least one alkyl polyethoxy(meth)acrylate of the formulawhere R1 is a hydrogen atom or a methyl group, R2 is a C1 to C4 alkyl group and n is an integer from 1 to 55,d) 0-10% by weight of at least one ethylenically unsaturated mono- or dicarboxylic acid, such as acrylic acid, methacrylic acid, maleic acid, itaconic acid, or anhydride, amide or hydroxyalkylamide thereof,e) 0-10% by weight of acrylonitrile or methacrylonitrile, andf) 0-50% by weight of further ethylenically unsaturated compounds other than a) to e).
