In this experimental study, we focus on the Ready-mixed concrete factory using reclaimed aggregate for concrete as building materials. In some Ready-mixed concrete factories, we mixed concrete using reclaimed aggregate, and tested fresh concrete and physical properties. The results show the following points: (1) concrete of using reclaimed aggregate until 20% is same as concrete using original aggregate in testing lab. and site plant (2) a reclaimed coarse aggregate kept for 1 month after collection can use ready-mixed concrete (3) a reclaimed coarse aggregate can be applied to strength class 45 in JIS A 5308.
