Abstract
The present invention is directed to a copolymer for use in a concrete admixture which improves the workability of hydraulic compositions such as cement paste, mortar, concrete and the like. Namely, the admixture effectively reduces the viscosity of the hydraulic compositions under shear without causing setting retardation of the compositions.
