Abstract

A superplasticizing additive for concrete and other cementitious mixes with high retention of workability (low "slump loss") and low air-entraining effect, is made by terpolymers of a) (meth)acrylic acid and its salts, b)polyethyleneglycolmonomethylether-(meth)acrylate and c) polypropyleneglycol-di(meth)acrylate.
