EQUIPMENT AND METHOD FOR REDUCING WATER ABSORPTION RATE OF REGENERATED FINE AGGREGATE

摘要

PPROBLEM TO BE SOLVED: To provide equipment and a method for reducing the water absorption rate of regenerated fine aggregate having particle diameters of 5 mm. PSOLUTION: The regenerated fine aggregate is obtained by grinding regenerated fine aggregate having particle diameters of 5 mm, separated from a regenerated aggregate obtained by crushing a concrete waste material, with an inertial conical grinding machine 3 and classifying the regenerated aggregate and cement fine particles in a ground material discharged from the inertial conical grinding machine 3.
