SUPERPLASTICIZER FOR HIGH FLOW AND HIGH STRENGTH

摘要

The present invention is conducted in the cement, and as the concrete admixture for, more specifically, composed mainly of a water-soluble vinyl copolymer having a repeating unit represented by the formula 1-4 in the small intestine ratio in all the structural units, the monomer with a sulfonic group contains essentially as has a function as a common cement and concrete admixture for addition, to give it the flow characteristics and the supervision function of the composition of a cement composition containing such as an aluminate content of high cement paste, mortar, concrete, and improving the slump retention performance of the work to improve the efficiency and workability and inhibit premature reduction in strength of the concrete by condensation delay relates to a cement admixture and a high-performance concrete for being capable of imparting a sufficient strength to the initial cure.
