Zusammenfassung:	PURPOSE:To uniformly and efficiently cool mixed aggregate by charging fine aggregate and coarse aggregate each having a prescribed water content for concrete before kneading into a vacuum cooling vessel so that the coarse aggregate is uniformly distributed in the fine aggregate and by carrying out vacuum cooling. CONSTITUTION:Fine aggregate and coarse aggregate each having a prescribed water content for concrete before kneading are charged into a vacuum cooling vessel so that the coarse aggregate is uniformly distributed in the fine aggregate, the vessel is evacuated to drop the temp. of the mixed aggregate and prescribed amts. of cement and water are added and kneaded with the mixed aggregate.
