This research was conducted with the use of recycled aggregate as modification. In terms of the use of recycled aggregate, the percentage of recycled aggregate should be determined because the strength of concrete would not be obtained by the high percentage of recycled aggregate.The scope of study is about comparison between recycle coarse aggregate and natural aggregate in terms of specific gravity, apparent specific gravity, absorption, los Angeles. Moreover, this research will also focus on the comparison between recycled aggregate for 0%, 35%, 50% and 65% replacement.
