This study investigates the fundamental properties of concrete using recycled coarse aggregate produced by bar-crusher. Test showed that using bar-crusher (s) had the most favorable results in fluidity and air content, compared with con-crusher (C), impact-crusher (I) and control concrete. In addition, increase of turning velocity rate of S, incorporating ratio of recycled aggregate and maximum size of aggregate caused increase of fluidity. Meanwhile, using S and C exhibited effective compressive strength value than I. For the turning velocity of S, C and I, most specimens showed less than 10% of strength reduction, which is acceptable. At the
rate of 500ppm, the strength of concrete had the most favorable value. Even though an increase of incorporating ratio of recycled aggregate decreased the strength value, using less than 25% of incorporating ratio exhibited less than 10% of strength reduction ratio. This is determined that 25% of incorporating ratio of recycled aggregate will have favorable performance.
