Referring table 4, parable density value for both the aggregate is 2.70 for natural aggregate and 2.42 for recycle aggregate. The difference indicates that natural aggregate is denser than recycle aggregate. In addition, this also shows that the recycle aggregate mass is lighter compared with natural aggregate at a rate of the same volume.
