    • 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.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.
    • 要解决的问题:提供一种通过使用在流动性,快速固化和快速干燥之间具有优异平衡的自流平材料来构造适于构造排水坡度的混凝土地板结构的方法; 和通过该方法制造的地板结构。 解决方案:一种用于构建自流平材料浆料的方法包括将通过将自流平材料和水捏合而制备的自流平材料浆料放置在建筑物地板的顶面上以形成固化的步骤 浆料层。 自流平材料包括由20〜80质量%的氧化铝水泥,5〜70质量%的波特兰水泥和5〜45质量%的石膏,流化剂和增稠剂形成的液压固定组分。 增稠剂含有平均粒径为30μm以下的纤维素增
