ABSTRACT:
The invention concerns the use of water-soluble polysaccharide derivatives as dispersing agents for mineral binder suspensions. A partially hydrolyzed cellulose containing carboxyl groups and optionally hydroxyalkyl and/or sulfate groups and/or a partially hydrolyzed amylose-rich starch which also has sulfoalkyl groups with 1 to 4 carbon atoms is used as the polysaccharide derivative. These polysaccharide derivatives have a low viscosity and an excellent plasticizing effect in mineral binder suspensions, especially in those based on cement, lime and/or gypsum.
