SELF-LEVELLING MATERIAL AND CONCRETE FLOOR STRUCTURE
To provide a self-levelling material having quick hardening and quick drying property, and further hardly reducing adhesiveness to an underlayer concrete even when used at inside and outside locations which are easily affected by environment such as water immersion or temperature change, and excellent in weather resistance.SOLUTION: A water hard component contains Portland cement of 15 to 45 mass%, alumina cement of 35 to 65 mass% and gypsum of 20 to 40 mass%. Content of a re-emulsified resin powder is 1 to 15 pts.mass based on 100 pts.mass of the water hard component. Content of a blast furnace slag fine powder is 40 to 120 pts.mass based on 100 pts.mass of the water hard component. Content of a fine aggregate is 80 to 200 pts.mass based on 100 pts.mass of the water hard component. A hardening accelerator contains a lithium salt. Content of the lithium salt is 0.01 to 2.0 pts.mass based on 100 pts.mass of the water hard component. Content of an aliphatic acid metal salt is 0.1 to 2 pts.mass based on 100 pts.mass of the water hard component.SELECTED DRAWING: Figure 1
【課題】速硬速乾性を有し、更に、屋外や屋内であって水分の浸入又は温度変化が大きく環境の影響を受け易い箇所で使用した場合であっても下地コンクリートに対する接着性が低下しにくい、耐候性に優れたセルフレベリング材を提供する。【解決手段】水硬性成分は、ポルトランドセメント１５〜４５質量％、アルミナセメント３５〜６５質量％及び石膏２０〜４０質量％を含む。再乳化樹脂粉末の含有量が、水硬性成分１００質量部に対して１〜１５質量部である。高炉スラグ微粉末の含有量が、水硬性成分１００質量部に対して４０〜１２０質量部である。細骨材の含有量が、水硬性成分１００質量部に対して８０〜２００質量部である。硬化促進剤が、リチウム塩を含む。リチウム塩の含有量が、水硬性成分１００質量部に対して０．０１〜２．０質量部である。脂肪酸金属塩の含有量が、水硬性成分１００質量部に対して０．１〜２質量部である。【選択図】図１
