METHOD FOR SEPARATING AGGREGATE FROM READY-MIXED CONCRETE AND CONCRETE UTILIZING THE AGGREGATE

摘要

PROBLEM TO BE SOLVED: To provide a method whereby ready-mixed concrete is prevented from hardening while being allowed to coagulate, thus enabling an aggregate and a powder mixture to be taken out of an excess of ready-mixed concrete and recycled.

SOLUTION: An agent that prevents the hardening of cement in ready-mixed concrete but permits the coagulation of cement is mixed into ready-mixed concrete; the resultant concrete coagulated but prevented from hardening is crushed with a non-pressurizing crushing means ed method; then, the aggregate is separated from other materials to selectively take out the aggregate.
