[problem] provides a kind of quick solid cement composition, can manufacture any middle hard cement composition for assigning dimensional stability, intensity expression power and beautiful excellent solidified body solidified in air in water in maintenance, and storage-stable is good. [solution] includes the quick hard conating of amorphous calcium aluminate, gypsum and Al2O3-SO3 based compounds. Relative to the amorphous calcium aluminate of 100 mass parts, the content of gypsum is 50 ~ 120 mass parts, and it is 5 ~ 20 mass parts that the content of Al2O3-SO3 based compounds, which is 100 mass parts amorphous calcium aluminates,. In addition, Al2O3-SO3 based compounds are noncrystalline, and are reduced to 5 ~ 40 mass % when standing at 500 DEG C. [selection figure] is not necessarily to
