| titleOfInvention | Additives for cement |
| abstract | PROBLEM TO BE SOLVED: To provide an additive for cement which provides a cement composition whose compressive strength is drastically improved with a small amount of addition. SOLUTION: The cement additive of the present invention is a cement additive comprising a vinyl alcohol-based polymer containing 0.1 to 45 mol% of a structural unit represented by the following Chemical Formula 1 or the like. Embedded image (Where R 1 , R 2 , R 3 , R 4 and R 5 represent a hydrogen atom or a hydrocarbon group having 8 or less carbon atoms which may have a substituent, S represents a sulfur atom, X Is a carboxyl group, It represents a monovalent group containing a sulfonic acid group, a hydroxyl group, an amide group, and a quaternary ammonium base. ) |
