Beschreibung
Zusammenfassung:	An admixture for cement, including: A) a comb polymer comprising the following partial structural units or consisting thereof: a) a mole fractions of a partial structural unit S1 of formula (I)b) b mole fractions of a partial structural unit S2 of formula (II)where M, Ru, Rv, m and R1 are as defined in the invention; and B) optionally, alkanol amine.The admixture for cement can provide remarkable improvement effects, particularly in milling aid effect, water-reducing properties, slump, fluidity and strength, for cements containing inferior or cheap mineral aggregate.
