Abstract
A dispersant for use with concrete or cement, and a concrete or cement admixture that comprises a cementitious material, water, and the dispersant. The dispersant includes a polymeric derivative of carboxylic acid, and has a sulfur-containing moiety that is covalently bonded thereto. Adding the dispersant to the cementitious material and water improves the rheological properties of the admixture.
