COMPONENT OF HIGH-FLOW CONCRETE, AND METHOD FOR PRODUCING HIGH-FLOW CONCRETE

摘要

PROBLEM TO BE SOLVED: To provide a method for producing high-flow concrete using recycled aggregate.

SOLUTION: The component of the high-flow concrete comprises recycled coarse aggregate as coarse aggregate and/or recycled fine aggregate as fine aggregate. The recycled coarse aggregate is adjusted so that it is in a saturated and surface-dried condition or in a water-containing condition having a surface moisture of 0.5% and satisfies the particle size distribution as shown below. The recycled fine aggregate is adjusted so that it is in a water-containing condition where the percentage of the moisture content to the absolute dry condition or water absorption is 0.1% or less and satisfies the particle size distribution as shown in the table.
