PROBLEM TO BE SOLVED: To provide a self-leveling mortar that ensures moderate construction work time even under a low-temperature work environment, for example 5°C, and when used for floor material and the like, allows it to be used within 24 hours after the finish of construction work: and in this way, has a short construction period and prevents material separation or cracking.SOLUTION: A self-leveling mortar contains Portland cement 100 pts.mass, alumina cement 4-12 pts.mass, gypsum 6-8 pts.mass, a water-reducing agent 0.3-0.7 pts.mass made from a mixture of a polyether water-reducing agent and a polycarboxylic acid water-reducing agent, with the content of the polyether water-reducing agent of 50-80 mass%, a setting retarder 0.12-0.16 pts.mass, a thickener 0.2-0.5 pts.mass, an alkali metal carbonate 0.06-0.1 pts.mass and a fine aggregate 140-180 pts.mass.SELECTED DRAWING: None
【課題】 例えば５℃といった低温作業環境下でも、適度な施工作業時間を確保でき、床材等に用いたとき、施工作業終了から２４時間以内に使用できるような、施工工期が短く、材料分離やひび割れが起こり難い自己平滑性モルタルを提供する。【解決手段】 ポルトランドセメント１００質量部、アルミナセメント４〜１２質量部、石膏類６〜８質量部、ポリエーテル系減水剤の含有率が５０〜８０質量％のポリエーテル系減水剤とポリカルボン酸系減水剤との混合減水剤０．３〜０．７質量部、凝結遅延剤０．１２〜０．１６質量部、増粘剤０．２〜０．５質量部と、アルカリ金属炭酸塩０．０６〜０．１質量部および細骨材１４０〜１８０量重量部とを含有する自己平滑性モルタル。【選択図】 なし
