PROBLEM TO BE SOLVED: To provide a method for preventing ready-mixed concrete calcium from adhering by separating/flocculating a ready-mixed concrete adhering to manufacturing, conveyance and waste water treatment facilities in a ready-mixed concrete mill. SOLUTION: In this method, an anti-adhesion flocculant of ready-mixed concrete calcium obtained by adding an anionic powdered flocculant composed mainly of polyacrylamide, is added to an inorganic flocculating/settling agent composed mainly of calcium sulfate and this mixture is stirred. Further, the adhesion of the ready-mixed concrete calcium can be easily prevented from occurring by separating/flocculating the ready-mixed concrete adhering to the manufacturing, conveyance and waste water treatment facilities of the ready-mixed concrete mill.
