Zusammenfassung:	PROBLEM TO BE SOLVED: To provide paving concrete which may highly exhibit long-term strength as well as initial strength and has a long life, and by which traffic may be restored extremely early after the start of paving work.SOLUTION: Paving concrete is obtained by curing a concrete composition at least comprising a pozzolanic fine powder with a BET specific surface area of 15 to 25 m/g, a blast furnace slag powder with a Blaine specific surface area of 5000 to 12000 cm/g, anhydrous gypsum with a Blaine specific surface area of 3000 to 12000 cm/g, and a binder including cement, and the paving concrete has bending strength of 3.5 N/mmor more at an age of 1 day.
