Cement material |
| abstract |
PROBLEM TO BE SOLVED: To provide a cement material capable of producing a hardened cement body having a compressive strength exceeding 250 N / mm 2 even under conditions that can be applied practically. SOLUTION: A cement component containing cement and silica fume, a high-purity silica mineral composed of powder containing SiO 2 exceeding 97 mass% and having an average particle diameter exceeding 30 μm, and water are contained per 1 m 3 . when the mass of water contained a (kg) W, mass (kg) Si of high purity silica minerals contained per 1 m 3, the cement component contained per 1 m 3 mass (kg) was as C, the following formula A cement material satisfying (1) and (2). W / C ≦ 0.21 (1) 0.04 ≦ Si / (C + Si) ≦ 0.33 (2) [Selection figure] None |
