摘要
The present invention relates to a polycarbonic acid-based cement dispersant, a method for preparing the same, and a mortar·concrete admixture using the polycarbonic acid-based cement dispersant. The cement dispersant of the present invention and the mortar·concrete admixture using the cement dispersant are applied to a cement composition such as a cement paste, mortar, concrete, etc., enhance a dispersion and retention force between cement molecules, have excellent fluidity due to the suppression of slump loss, and have an effect of improving workability, such as shortening a concrete mixing time by 20% or more. Further, the mortar·concrete admixture using the cement dispersant of the present invention has an effect of providing a very good concrete condition and an appropriate compressive strength over time.
