PROBLEM TO BE SOLVED: To provide a method of manufacturing a fluidized concrete requiring no special kneading at sites, having curable characteristic equal to a base concrete, and high flowability and enough material separation resistance.SOLUTION: A method of manufacturing a fluidized concrete includes a process (a) of mixing and kneading a hydraulic binder, a fine aggregate, a coarse aggregate, water and a water-reducing agent for concrete to obtain a base concrete having a slump value according to the definition by JIS A 1101 of 15 to 21 cm, and a process (b) of adding a viscosity adjusting component consisting of an aqueous polymer containing a monomer which is a sulfo group-containing (meth)acrylic derivative as a constitutional unit and a fluidizing agent for viscosity adjusting component one-liquid type concrete to the base concrete having a slump value according to the definition by JIS A 1101 of 12 to 21 cm over time of 5 to 180 min. after the process (a) and kneading to obtain a fluidized concrete having a slump flow value according to the definition by JIS A 1150 of 35 to 65 cm. |
