Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a self-leveling material which, even when portland cement is used as the main component of a hydraulic component, has sufficiently high working efficiency and curing properties and, particularly, ensures excellent dimensional stability even at low temperatures.SOLUTION: The self-leveling material contains: a hydraulic component comprising 40-60 mass% of portland cement, 15-40 mass% of alumina cement and 10-30 mass% of gypsum; blast furnace slag; fine aggregate; a fluidizing agent; and a setting modifier. The fine aggregate contains 4 mass% of blast furnace slag having a Blaine specific surface area of 6,000-10,000 cm/g in 100 mass% of the blast furnace slag.
