PROCESS FOR TREATMENT OF RESIDUAL READY MIXED CONCRETE, RECYCLED CEMENT, AND AGGREGATE FOR CONCRETE

摘要

A process for the treatment of residual ready mixed concrete which permits easy separation and recovery and can bring about a recyclable aggregate and recyclable fine powder. More specifically, a process for the treatment of residual ready mixed concrete which comprises the mixing/agitation step (3) of mixing returned ready mixed concrete and/or ready mixed concrete sludge as residual ready mixed concrete with a dry aggregate and/or dry fine powder as dry raw material under agitation to form a mixed raw material (30) through the adhesion of water contained in the residual ready mixed concrete to the dry raw material and the absorption thereof by the dry raw material and the classification step (4) of classifying the mixed raw material (30) into an aggregate and fine powder.
