    摘要: Water-soluble formaldehyde-free polycondensation products based on amino-s-triazines with at least two amino groups and glyoxylic acid, which contain as further component at least one amino compound and where the molar ratio of amino-s-triazine to glyoxylic acid to amino compound is 1:0.5 to 6.0:0.1 to 2.0. These polycondensation products are excellently suited as additives for aqueous suspensions of inorganic binders, especially cement, lime and gypsum. Building material mixtures which contain these polycondensation products remain workable for a considerably longer time and, in spite of this, also set more quickly.
