| titleOfInvention | Cement mortar and concrete composition and method for producing the same |
| abstract | PROBLEM TO BE SOLVED: To generate sufficient strength under a low temperature environment, to exhibit excellent rapid hardening performance with excellent hydration activity and at the same time to sufficiently secure predetermined fluidity, and to generate initial shrinkage cracks due to self-contraction The present invention provides an admixture composition for cement and a method for producing the same, and a cement composition using the admixture composition for a cement and a method for producing the same. SOLUTION: A cement mortar / concrete composition comprises a rapid hardening additive for cement containing a C 12 A 7- based mineral phase, gypsum, an alkali sulfate compound, a calcium salt and lithium carbonate, and C 12 A 36-55% by mass of 7 series minerals, 0.3-1.7% by mass of alkali sulfate compound (in terms of sodium sulfate), 0.01-1.3% by mass of lithium carbonate (in terms of lithium), calcium salt (water Containing 1 to 14 mass% of calcium oxide), the mass ratio of the content of gypsum (equivalent to anhydrous gypsum) / C 12 A 7- based mineral phase is 0.5 to 1.2, and measured by X-ray diffraction Cementing admixture composition having a crystallite diameter of 150 to 500 nm and a lattice constant of 11.940 to 11.975 Å of a C 12 A 7- based mineral phase, (2) cement, (3) lithium salts other than lithium carbonate and 4 A carbonate containing 0.01 to 0.15 mass% of the lithium salt (in terms of lithium) by external ratio, based on the total mass of the admixture composition for cement and cement, the carbonate (in terms of CO 3 ) In an amount of 0.05 to 0.6% by mass. [Selected figure] None |
