Kind Code: A1 The present invention has mechanical properties such as self-filling property (high fluidity) and good material separation resistance before curing, excellent in workability, and having a compressive strength exceeding 120 MPa after curing. Provide high fluidity concrete excellent in quality. A high-flow concrete, (A) and cement 100 parts by weight of the Blaine specific surface area 2,500~5,000cm 2 / g, (B) fine particles 10 to 40 mass having a BET specific surface area of 5~25m 2 / g Part, (C) 10 to 50 parts by mass of inorganic particles A having a brane specific surface area of 5,000 to 30,000 cm 2 / g, (D) fine aggregate, (E) coarse aggregate, and (F) water reducing agent And (G) water, and the inorganic particles A have a larger Blaine specific surface area than cement. The high-fluidity concrete has a slump flow value of 45 to 80 cm measured according to "JIS A 1150 (concrete slump flow test method)", and has a compressive strength of 120 N after being cured in water until the age of 91 days. / Mm 2 or more.
