HIGH DURABLE MORTAR AND HIGH DURABILITY CONCRETE
PROBLEM TO BE SOLVED: To provide a high durable mortar capable of achieving all of chloride penetration resistance, dry shrinkage inhibition, resistance to freezing damage and compressive strength at sufficiently high level while sufficiently maintaining resistance to neutralization and concrete containing the same.SOLUTION: There is provided a high durable mortar containing a binding material, a silica fume, metakaolin, water, fine aggregate and a chemical admixture with 1 to 15 pts.mass of the silica fume and 1 to 15 pts.mass of metakaolin based on 100 pts.mass of the binding material containing cement and a ratio of total mass A of the binding material, the silica fume and the metakaolin and mass B of water (B/A) of 0.20 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０．２０〜０．６５である高耐久性モルタル。【選択図】なし
