ДОБАВКА ДЛЯ СТРОИТЕЛЬНЫХ ХИМИЧЕСКИХ КОМПОЗИЦИЙ
The present invention concerns an additive for construction chemical compositions, in particular mortar and cement compositions. The additive comprises at least one amide or ester of a sugar acid and at least one water-soluble comb polymer which contains, on the main chain, acid functions and side chains having ether functions. The additive is useful for retarding the hardening of a construction chemical composition.
