This study was performed to evaluate fluidity of super flow concrete using recycled coarse aggregate.The unit weight was 2,246~2,344 kg/㎥, the unit weights of these concrete were decreased with increasing the content of fly ash and recycled coarse aggregate.The slump flow was 58~63㎝, the Box type passing was 3.4~6.8㎝, respectively. The L type compacting was excellent in the fly ash content 10% and 20%, but, it was showed in good in the fly ash content 30%.The super flow concretes using recycled coarse aggregate were improved by substitution in the range of less than the fly ash content 20% and recycled coarse aggregate content 75%.This recycled coarse aggregate can be used for super flow concrete.
