摘要： A hardened cement material having enhanced flexural strength, heat resistance, and water resistance prepared from a cement composition comprising 100 parts by weight of a hydraulic cement material containing .gamma.-dicalcium silicate (.gamma.-C.sub.2 S) preferably in an amount of 1% by weight or more and 1 to 20 parts by weight of a water-dispersible polymeric material, and mixed with 5 to 25 parts by weight of water, by a molding procedure and by a heat-hardening procedure at a temperature of from 40.degree. C. to 180.degree. C. while controlling the relative humidity to 20% to 70% and/or applying a pressure of 5 to 15 atmospheres.
