PROBLEM TO BE SOLVED: To provide a hydraulic composition having high fluidity, rapidly advancing the hardening after the finish of construction work while keeping usable life sufficient to easily carry out the construction work and obtaining excellent leveling property and surface finishing property and particularly having self leveling property by which the remarkable surface finishing property is attained even in construction under a high temperature environment. SOLUTION: The hydraulic composition having self fluidity contains a hydraulic component comprising alumina cement, portland cement and gypsum, a setting accelerator and fine aggregate. The setting accelerator contains potassium sulfate and a lithium salt. The fine aggregate contains 3-20 mass% fine particles of 30-150μm and 97-80 mass% particle of 150-850μm, based on 100 mass% fine aggregate. COPYRIGHT: (C)2008,JPO&INPIT |
