Effect of Recycled Coarse Aggregate on Concrete

The fine and coarse aggregates generally use 60% to 75% of the concrete volume (70% to 85% by mass) and will influence the concrete’s freshly mixed and hardened properties, mixture proportions, and economy. Moreover, fine aggregate usually consists of natural sand with particles around 4.75mm (0.2 in); then in terms of coarse aggregate it is
