ДОБАВКА ДЛЯ ГИДРАВЛИЧЕСКИ ТВЕРДЕЮЩИХ СОСТАВОВ
The present invention relates to an additive for hydraulically setting compositions, comprising a colloidally disperse preparation of at least one salt of a mono- or polyvalent metal cation and of at least one compound which is able to release an anion which forms a low-solubility salt with the metal cation, and of at least one polymeric sulphonated dispersant. The additive is suitable particularly as a slump retainer.
