Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a hydraulic composition for ultrahigh strength concrete extending a slump value range in which a centrifugally molded and hardened product having good finish and good hardening strength is obtained, when a hardened concrete product is produced by centrifugal molding from ready-mixed ultrahigh strength concrete. SOLUTION: The hydraulic composition for ultrahigh strength concrete includes cement, an inorganic powder, a specific dispersant composition and water, and has a W/P ratio of 10-25 wt.% and a slump value of 0-5 cm.
