Particle size distribution curves of recycled aggregates from building demolition concrete crushed by jaw and impact crushers. The jaw crusher produced 60% of coarse aggregates in weight, whereas the impact crusher produced 49% coarse aggregates. The proportion of particles finer than 0.15 mm is around 7–8% weight for both crushing mechanisms.

This paper studied the effect of aggregate properties on the crushing strength of concrete. In order to achieve the study objective, three types of coarse aggregates, brick khoa, shingles stone, and black stone were used to test. And the test results show that concrete made from black stone has the highest workability followed by shingles stone & brick khoa of aggregates.

Crushed concrete aggregates are pieces of old concrete buildings, roads, and other destroyed concrete structures that are crushed in a crushing machine. This crushed material is then washed clean, then broken up into smaller fragments. The fragments are added to other materials, including concrete, to create recycled aggregate.

Small pieces of scrap metal often go through the concrete crusher. After processing, it can be removed using an electromagnet. The concrete may go through a jawbreaker first, then an impactor and finally sorted using a screener. The screener will stockpile the crushed concrete into aggregate size, for example, 25mm 12mm 5mm to dust.
