    Abstract: The invention relates to a method for the manufacture of concrete with a high early strength, to concrete with a high early strength and to application of concrete with a high early strength. The method is characterized in that for the manufacture of the concrete, which involves the mixing of a bonding agent, gravel, a composition of aggregates and water, not one aggregate, but two different aggregates are used. More preferably, the two aggregates are limestone flour and pumice stone, with between 30 and 50 weight percent of the total weight of pumice stone and limestone flour being made up of pumice stone and 50 to 70 weight percent of limestone flour.

    Abstract: PROBLEM TO BE SOLVED: To provide a concrete composition for centrifugal casting developing high strength in centrifugally casted concrete secondary products such as a pile, a pole, a Hume pipe and the like. SOLUTION: The concrete composition for centrifugal casting developing high strength contains high-early strength portland cement, a high strength admixture, a dispersant, an aggregate and water and is characterized by that the content of hemihydrate gypsum in the high-early strength portland cement is 20-80 mass%, the high strength admixture contains anhydrous gypsum and amorphous silica, the mass ratio of anhydrous gypsum to amorphous silica in the high strength admixture is 15/85-80/20 and the dispersant is a polycarboxylic acid-based dispersant.
