SELF-LEVELLING MATERIAL, SELF-LEVELLING MATERIAL SLURRY AND CURED BODY
PROBLEM TO BE SOLVED: To provide a self-levelling material capable of forming a cured body exhibiting good compressive strength while having good surface property and providing a self-levelling material slurry having excellent flowability.SOLUTION: There is provided a self-levelling material which contains a hydraulic component, a blast furnace slag fine powder, a fine aggregate, a fluidization agent, a thickener and a setting modifier. The blended percentage of the hydraulic component is: Portland cement of 15 to 55 mass%, alumina cement of 15 to 55 mass% and gypsum of 5 to 35 mass%, a Blaine specific surface area of the gypsum is 2000 to 6000 cm/g, a content of the blast furnace slag fine powder is 70 to 140 pts.mass based on 100 pts.mass of the hydraulic component, a content of the fine aggregate is 160 to 260 pts.mass based on 100 pts.mass of the hydraulic component, and the fine aggregate is prepared so that its water percentage content is in a range of 1.00 to 1.70%.SELECTED DRAWING: Figure 1
【課題】 良好な表面性状を有しつつ、良好な圧縮強度を発現する硬化体を形成可能であり、さらに流動性に優れたセルフレベリング材スラリーを得ることが可能なセルフレベリング材を提供することを目的とする。【解決手段】 水硬性成分、高炉スラグ微粉末、細骨材、流動化剤、増粘剤及び凝結調整剤を含有するセルフレベリング材であって、水硬性成分の配合割合がポルトランドセメント１５〜５５質量％、アルミナセメント１５〜５５質量％及び石膏５〜３５質量％であり、石膏のブレーン比表面積が２０００〜６０００ｃｍ２／ｇであり、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７０〜１４０質量部であり、細骨材の含有量が、水硬性成分１００質量部に対して１６０〜２６０質量部であり、細骨材の含水率が１．００〜１．７０％の範囲に調製された細骨材であるセルフレベリング材。【選択図】 図１
