This study is aimed to utilize for basic material of concrete quality management through evaluate properties of fresh and hardened concrete with the aggregate quality. As a result, fine aggregate`s slump change of between one grade was 8~82% and in case of coarse aggregate, slump change of between one grade was 2~22% on same mixing condition. The unit water for same workability condition, unit water was increased 16kg/m3 with decreasing of one grade for fine aggregate and unit water was increased 5kg/m3 with decreasing of one grade for coarse aggregate.
