QUICK-HARDENING REPAIR MORTAR MATERIAL, QUICK-HARDENING REPAIR MORTAR COMPOSITION, AND HARDENED BODY
To provide: a quick-hardening repair mortar material which contains a certain amount of chlorine, achieves high fluidity and low mixing resistance by mixing a specific material and a fine aggregate, and allows increase in neutralization resistance, adhesion strength to reinforcing bars, and the anti-corrosion rate of reinforcing bars; a quick-hardening repair mortar composition; and a hardened body.SOLUTION: The quick-hardening repair mortar material comprises cement, a calcium aluminate, gypsum, a polymer emulsion, a fiber, and a fine aggregate, wherein the amount of chlorine is 3 ppm-1,800 ppm.SELECTED DRAWING: None
【課題】特定の塩素量を含有し、特定の材料と細骨材を組み合わせることで、流動性が高く、練り混ぜ抵抗性が低く、中性化抵抗性や鉄筋との付着強度、鉄筋の防錆率をより高めることができる急硬補修モルタル材料、急硬補修モルタル組成物及び硬化体を提供する。【解決手段】セメント、カルシウムアルミネート、石膏、ポリマーエマルジョン、繊維、細骨材からなる急硬補修モルタル材料であって、塩素の量が３ｐｐｍ以上１，８００ｐｐｍ以下である、急硬補修モルタル材料。【選択図】なし
