| titleOfInvention | Cement composition and method for producing hardened cement |
| abstract | The present invention provides a cement composition capable of producing a cement hardened body that can maintain fluidity for a relatively long time and can obtain a practical strength in a relatively short time at a low cost. A cement composition containing Portland cement, lithium sulfate, and a polycarboxylic acid-based admixture, wherein the polycarboxylic acid-based admixture comprises a monomer represented by general formula (1), a general formula (1) 2) A copolymer having a monomer is contained, and the concentration of the copolymer with respect to Portland cement is 0.3 to 0.52% by mass. (R 1 is the same or different and is a hydrogen atom or an alkyl group having 1 to 18 carbon atoms. N is an average added mole number of 10 to 300.) (M is a hydrogen atom, a monovalent metal atom, a divalent metal atom, an ammonium group or an organic amine group.) [Selection figure] None |
