Cement dispersant, its production process, and cement composition using the cement dispersant |
| abstract |
Disclosed are the following: a cement dispersant which is excellent in initialndispersibility and further in flow retainability of cement, because of using a polymernhaving a proper molecular weight distribution; a process for producing this cementndispersant; and a cement composition using this cement dispersant. The cementndispersant comprises a water-soluble polymer (P) as a main component, and isncharacterized by displaying an area proportion (a value (A - B) given by subtractingnan area ratio B of a lower molecular weight side portion from an area ratio A of anhigher molecular weight side portion) in the range of 13 to 60 %. |
