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 aggregates that …

Real-scale applications of recycled aggregate concrete

aggregates were used for the exposed-aggregate concrete. As the maximum aggregate is 8 mm, the top lift is only 4 cm thick. The two lifts are placed fresh on fresh. Recycling the pavement and stabilising the existing sub-base was about 5% cheaper than the conventional alternative without taking into account the environmental benefits.
