To provide a composition for a plastered-floor undercoat which can prevent an influence of unevenness or inclination of a concrete floor surface on a plaster-finished floor surface in forming a plaster-finished concrete floor structure, quickly achieve a water content of a plastered-floor undercoat layer of less than 5% (the D value of less than 690), that is an undercoat condition for suitably executing using a plastered-floor material, and further obtain an excellent adhesive strength characteristic as the plaster-finished concrete floor structure.
The self-fluidizing hydraulic composition contains a hydraulic component (100 mass%) consisting of alumina cement of 20-80 mass%, portland cement of 10-70 mass% and gypsum of 5-45 mass%, an inorganic fine powder, a fine aggregate, a resin powder and further at least one or more component selected from a setting modifier, a fluidizing agent, a thickener and an anti-foaming agent.
