    Abstract: PROBLEM TO BE SOLVED: To provide an ultrarapid hardening grout composition where a long usable time of about 60 minutes can be assured with superior strength development and without lowering compressive strength at a young material age of about 2 hours and where bleeding suppression function, defoaming function and suitable fluidity are assured.
    SOLUTION: The grout composition involves an admixture including a coagulation moderator consisting of sodium aluminate, an inorganic carbonate and carboxylic acids at a specified ratio to a rapid hardening ingredient in which calcium aluminate whose vitrification rate is 80% or more and an inorganic sulfate are mixed at a specified mass ratio, a cement mineral, quick lime, a defoamer and a thickener. The coagulation moderator contains first particles having a mean particle diameter of more than 45 μm and 90 μm or less of 10-45 mass%, second particles having a mean particle diameter of more than 90 μm and 150 μm or less of 30-70 mass% and third particles having a mean particle diameter of more than 150 μm and 500 μm or less of 5-30 mass%. The second particles are contained more than the third particles.
