CEMENT ADDITIVE, CEMENT ADMIXTURE, CEMENT COMPOSITION, MOLDED BODY, AND METHOD FOR IMPROVING STRENGTH OF MOLDED BODY
Provided is an additive for concrete in which viscosity of a cement composition is low and fluidity is high at an initial stage of casting even when the additive is added, and long-term strength of concrete or the like improves by the addition. A cement additive comprising a water-absorbent resin, wherein the water-absorbent resin is formed by polymerizing a monomer mixture containing no less than 50 mol % of a nonionic non-crosslinkable monomer and no less than 0.1 mol % of a nonionic crosslinkable monomer, and a content of an anionic monomer in the monomer mixture is no more than 20 mol %.
