Concrete admixture |
摘要 |
The present invention provides a concrete admixture which is useful in the field of a highly strong concrete, which has a high flowability and which is excellent in an applicability of a concrete paste. That is, the present invention provides a concrete admixture comprising a copolymer-mixture obtained by copolymerizing a specific monomer (A) such as an ethylene-based unsaturated carboxylic acid-derivative having a polyoxyalkylene group and a specific monomer (B) such as a (meth)acrylic acid with changing the molar ratio of (A)/(B) at least one time in the polymerization course, as well as a concrete composition comprising the said concrete admixture.
