This study was performed to evaluate fluidity of super flow concrete using recycled coarse aggregate. The unit weight was $2,246{sim}2,344;kg/m^3$, the unit weights of these concrete were decreased with increasing the content of fly ash and recycled coarse aggregate. The slump flow was $58{sim}63;cm$, the Box type passing was $3.4{sim}6.8;cm$, 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.
