PURPOSE:To obtain a grout which little suffers bleeding and has a long flow retention time and an excellent property of developing strengths. CONSTITUTION:A grout comprising a mixture obtained by grinding a mixture of clinker for high-early-strength cement, clinker for normal cement and gypsum dihydrate and an inorganic powder in a mixing ratio of the clinker for the high-early-strength cement to the clinker for the normal cement of 1:1 to 3:1 by weight and a mixing ratio of the total of the clinker for the high-early- strength cement and the clinker for the normal cement to the gypsum dihydrate (in terms of SO3) of 3-7wt.%. The Blaine value of the ground mixture is 4000-600cm<2>/g.
