OBJECTIVES To replace natural coarse aggregate by the recycled coarse aggregate in various percentages (0%, 30%, 60% and 100%) To study and compare the mechanical properties
Recycled aggregates are only classified as recycled concrete aggregates (RCA) when the primary material is concrete. By crushing and compressing existing waste concrete and combining it with aggregate, producers can create concrete aggregate to a specific size and quality, which makes it very cost effective to purchase.
