Experimental study on recycled coarse aggregate of concrete
For making recycled coarse aggregate, concrete from a nearby site was used in a testing machine and then by hand with hammers. The broken aggregates are then put through 20 mm, 16 mm, 10 mm, and 4.75 mm sieves, and the aggregates that stay in the 16 mm, 10 mm, and 4.75 mm sieves are used as recycled coarse …
