CONCRETE COMPOSITION AND METHOD FOR MANUFACTURING CONCRETE STRUCTURE

SATO SHUNSUKE / OKAYA HIROSHI

To provide: a concrete composition which has a small single fiber fineness and includes a reinforced fiber having a multileaf-shaped fiber cross section, and which also has constant flowability; and a method for manufacturing a concrete structure.SOLUTION: The invention relates to a concrete composition including cement, water, a fine aggregate, a coarse aggregate, a reinforced fiber, a fly ash, a thickener and a water-reducing agent. A slump value is 12-30 cm. The reinforced fiber has a multileaf-shaped cross section shape including three or more protrusions, and has a single fiber fineness of 0.5-4.2 dtex and a fiber length of 2-20 mm. The concrete composition includes 0.3-2.0 vol% of the reinforced fiber.SELECTED DRAWING: None
