Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a hydraulic composition which is suited for manufacturing a centrifugally molded hardened body having super high strength wherein the strength in a material age of about 1-7 days is not lower than 100 N/mm2and which is excellent in workability. SOLUTION: The hydraulic composition for the centrifugally molded hardened body comprises cement, hydraulic powder, an aggregate, a dispersant that contains water soluble salt of a condensate of naphthalenesulfonic acid and formaldehyde, and water, wherein the hydraulic composition has an initial slump value of 0-7 cm, an amount of destruction (defined in the specification) of 200 g or less, a water/powder weight ratio of 10/100-22/100, and a weight of powder of 450-1,000 kg/m3.
