Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a self-fluidity hydraulic composition having an excellent workability due to its high fluidity, a surface smoothness(flatness), a surface horizontality, a fast hardening property etc., in particular, having an excellent surface property that does not produce surface powdering or surface unevenness due to material separation or the water floating from the surface, while maintaining the high fluidity.SOLUTION: A self-fluidity hydraulic composition comprises: a hydraulic component; an inorganic powder; a fine aggregate; a fluidizer; a setting modifier; and a hydroxypropyl methylcellulose thickener. Here, the inorganic powder is one or more kinds selected from blast-furnace slag fine powder and limestone fine powder, and the hydroxypropyl methylcellulose thickener has a viscosity of at least 2,000 mPa s when measured as 2 mass% aqueous solution at 20°C and a viscosity measured as 1 mass% aqueous solution is at most 50,000 mPa s.
