<P>PROBLEM TO BE SOLVED: To provide a method for constructing a concrete floor structure suitable for constructing drainage slope through the use of self-levelling material having excellent balance among flowability, fast curing, and quick drying; and a floor structure produced by the method. <P>SOLUTION: A method for constructing a self-levelling material slurry includes a step of placing a self-levelling material slurry prepared by kneading a self-levelling material and water on the top face of a building floor so as to form a cured slurry layer. The self-levelling material includes a hydraulic setting component formed of 20 to 80 mass% of alumina cement, 5 to 70 mass% of Portland cement, and 5 to 45 mass% of gypsum, a fluidizing agent, and a thickener. The thickener contains a cellulose thickener and bentonite having an average particle diameter of 30 μm or less. The contents of the cellulose thickener and the bentonite relative to 100 mass parts of the hydraulic setting component satisfy a specific relation. <P>COPYRIGHT: (C)2013,JPO&INPIT |
