Abstract
The use of a three-component water-soluble polymer comprising 5–90% by weight of a component a), preferably of the maleic acid, fumaric acid or itaconic acid type, 5–90% by weight of a component b) essentially from the group consisting of 2-acrylamido-2-methylpropanesulfonic acid, vinylsulfonic acid and vinylphosphonic acid, and 5–90% by weight of a component c) comprising acrylic acid, methacrylic acid, acrylamide or methacrylamide, as fluidizer for refractory compositions comprising alumina cement is described. The copolymer, which has a preferred molecular weight Mof <50,000, can also be combined with further quality-improving additives such as silica, lime or soda and further customary additives for refractory compositions.
