description To provide a high durable mortar capable of achieving all of chloride osmosis resistance, dry shrinkage suppression, resistance to freezing damage and compression strength at sufficiently high level while maintaining resistance to neutralization sufficiently, and a concrete containing the same.SOLUTION: There is provided a high durable mortar containing a binding material, a silica fume, metakaolin, water, a fine aggregate, and a chemical admixture, in which the binding material contains cement, silica fume is contained at 1 to 15 pts.mass and the metakaolin is contained at 1 to 15 pts.mass based on 100 pts.mass of the binding material, and a ratio of mass of water B to total mass of the binding material, the silica fume and the metakaolin A (B/A) is 0.30 to 0.65.SELECTED DRAWING: None 【課題】中性化に対する抵抗性を十分に維持しながら、塩化物浸透抵抗性、乾燥収縮抑制、凍害に対する抵抗性及び圧縮強度の全てを十分高水準に達成し得る高耐久性モルタル及びこれを含むコンクリートを提供する。【解決手段】結合材と、シリカフュームと、メタカオリンと、水と、細骨材と、化学混和剤とを含む高耐久性モルタルであって、結合材はセメントを含み、結合材100質量部に対してシリカフュームを1〜15質量部含み且つメタカオリンを1〜15質量部含み、結合材とシリカフュームとメタカオリンの合計質量Aに対する水の質量Bの比(B/A)が0.30〜0.65である高耐久性モルタル。【選択図】なし
