More Information
Summary:The present invention relates to cement dispersant that is a copolymerizatio n product of a first monomer (A) comprising a carboxylic acid, a second monome r (B) comprising an alkoxylated allyl alcohol sulfate, and, optionally, a thir d monomer (C) comprising an alkoxylated allyl alcohol. The cement dispersant according to the invention provides improved slump life properties and water reduction properties in cement admixtures.
