Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a concrete for pavement that has excellent expression of long-term strength, excellent expression of initial strength and a long life, and can make a road available for traffic very soon after beginning of a paving work.SOLUTION: The concrete for pavement is formed by curing a concrete composition including at least portland blast furnace cements, a pozzolanic fine powder of a BET specific surface area of 15-25 m/g, and a binder containing anhydrous gypsum of a Blaine specific surface area of 3,000-12,000 cm/g. The concrete for pavement is characterized by having a bending strength of 3.5 N/mmor higher at a material age of one day.
