    • PROBLEM TO BE SOLVED: To provide a quick-hardening composition which is a hydration-hardening quick-hardening composition to be blended in mortar or concrete, has excellent weathering resistance enough to withstand satisfactorily even when stored in the atmosphere for a long period of time while dispensing with a special environmental control-considered storage facility or troublesome storage treatment, and exhibits high short-time strength stably after kneading water is injected therein.
      SOLUTION: The quick-hardening composition having hydration reactivity contains CaO and Al
      2 O
      3 as chemical components and a particulate mixture composed of particles having 0.5-0.85 molar ratio (CaO/Al
      2 O
      3 ) of CaO to Al
      2 O
      3 and 2 O
      3 ) of CaO to Al
      2 O
      3 and ≥10 μm particle size. The total content of CaO and Al
      2 O
      3 in the particulate mixture is ≥85 mass% (including 100 mass%).

    • PROBLEM TO BE SOLVED: To provide a grout composition which has excellent flowability, can compensate the settling or shrinkage of a grouting material that does not solidify yet, has excellent initial strength development even under a low-temperature environment down to 10°C and also is excellent in dimensional stability, and to provide mortar or concrete using the composition.
      SOLUTION: The grout composition contains: a hydraulic material having 3CaO-SiO
      2 solid solution, 11CaO-7Al
      2 O
      3 -CaF
      2 and anhydrous gypsum as effective components; a quick-hardening material having calcium aluminosilicate glass and anhydrous gypsum as effective components; fine powders of water-granulated blast furnace slag; silica fume; calcium hydroxide; a high-performance water-reducing agent; and a setting modifier. The composition may further contain calcium nitrite and/or calcium nitrate, and furthermore may contain a gas-foaming substance. The mortar or concrete is obtained by blending the above grout composition with aggregate and water, and the grouting material comprises the mortar or concrete.
