CORROSION RESISTANT MORTAR COMPOSITION
PROBLEM TO BE SOLVED: To provide a corrosion resistant mortar composition which is coated mortar capable of protecting concrete and mortar, is excellent in plasterer workability, pump press-feedability, sag resistance, dimensional stability and crack resistance, and is also excellent in acid resistance.SOLUTION: A corrosion resistant mortar composition does not substantially contain a polymer for cement, contains (A) cement, (B) blast furnace slag fine powder, (C) fly ash, (D) an expansive material, (E) a specific aggregate containing calcium and aluminum as chemical components, and (F) a thickener in a specific ratio, and preferably, further contains one or more selected from (G) a water-reducing agent, (H) a defoaming agent, (I) one or more components selected from alkali metal carbonate or formate, (J) sulfuric acid alkali metal salt, and (K) an organic fiber.SELECTED DRAWING: None
【課題】コンクリートやモルタルを保護し得る、被覆モルタルであり、左官施工性、ポンプ圧送性、垂れ抵抗性、付着性、形状寸法安定性及びひび割れ抵抗性に優れ、更に耐酸性に優れる耐食性モルタル組成物を提供。【解決手段】セメント用ポリマーを実質的に含まずに、（Ａ）セメントと、（Ｂ）高炉スラグ微粉末と、（Ｃ）フライアッシュと、（Ｄ）膨張材と、（Ｅ）カルシウムとアルミニウムを化学成分として含む特定の骨材と、（Ｆ）増粘剤とを特定の割合でモルタル組成物に含有し、更に、（Ｇ）減水剤、（Ｈ）消泡剤、（Ｉ）炭酸アルカリ金属塩又は蟻酸塩から選ばれる１種以上の成分、（Ｊ）硫酸アルカリ金属塩、（Ｋ）有機繊維から選ばれる１種以上を含むことが好ましい耐食性モルタル組成物。【選択図】なし
