| titleOfInvention | Cement additive and cement composition |
| abstract | PROBLEM TO BE SOLVED: To reduce the amount of water to be added to a cement composition, and to provide high dispersibility and excellent workability while reducing the amount of water to be added. An excellent cement additive and a cement composition using the same are provided. SOLUTION: The cement additive mainly comprising a polycarboxylic acid polymer (X) and a polycarboxylic acid polymer (Y), wherein the polycarboxylic acid polymer (X) has a repeating unit ( A), a repeating unit (B), a repeating unit (C), a repeating unit (D), and a repeating unit (E). The polycarboxylic acid polymer (Y) has a repeating unit (F) And S, T, E1, E2 and n in the polycarboxylic acid-based polymer (X) have T> 0, And (1), (2) and (3); (1) T / (T + E1 + E2) ≧ 0.1 (2) S> 0 (3) n ≧ 110. A cement additive that satisfies at least one of the requirements of 110. |
