| titleOfInvention | Cement composition |
| abstract | The present invention provides a cement composition that suppresses a rapid decrease in fluidity that occurs immediately after kneading and exhibits high strength. The present invention relates to a cement composition comprising mentoclinker and hemihydrate gypsum, wherein the cement clinker is 37 to 48% by mass of 3CaO.SiO2 and ˜5% by mass with respect to the mass of the cement composition. 3CaO · Al2O3, 40 to 250 mg of tin or a tin compound is further added to 1 kg of cement clinker in terms of tin, and the ratio of gypsum to the mass of the cement composition is 0.5 to 2.2 in terms of SO3. The brane specific surface area of the cement composition is 3200-3600 cm 2 / g, the gypsum contains hemihydrate gypsum, and the intensity of the 114 plane X-ray diffraction intensity relative to the 220 plane X-ray diffraction intensity of the hemihydrate gypsum. The ratio is 65-115. [Selection figure] None |
