摘要：
PROBLEM TO BE SOLVED: To provide a hydraulic composition for producing hydraulic mortar suppressing or delaying the occurrence of rust on the surface of a metal in contact with the hydraulic mortar when the mortar is placed to be in contact with the metal and having rapid hardening property and high strength of a hardened body. SOLUTION: The hydraulic composition contains a hydraulic component containing alumina cement, portland cement and gypsum hemihydrate and fine aggregate, wherein 20-27 mass% gypsum hemihydrate is contained per 100 mass% in total of the hydraulic component.
