| titleOfInvention | Cement water reducing agent, cement composition containing the same, and cured product |
| abstract | (57) [Summary] [Purpose] Not only does the fluidity of the cement composition change little over time and the workability is good, but the water reduction performance does not deteriorate when used in a cement composition with a small W / C value. Up, To provide a cement water reducing agent that is easy to manufacture, a cement composition suitable for high-strength concrete, which has good workability, and a high-strength cement hardened material suitable for high-rise buildings. [Claim] A cement water reducing agent containing at least the following components A and B, wherein the ratio of the components A and B is A: B = 9: 1 to 5: 5 in terms of solid content weight ratio. A cement water reducing agent characterized by: A component: 2,2-bis (4-hydroxyphenyl) propane (a), aminobenzenesulfonic acid (b), formaldehyde (c) and alkali (d), a: b : C: d = 0.9-1.1: 1: 2.3-2.7: 0.8- Condensate obtained by reacting under an aqueous condition at a molar ratio in the range of 1.2; Component B: Lignin sulfonic acid containing 5% by weight or less of reducing sugar. |
