Particle size distribution curves of recycled aggregates from concrete pavement crushed by jaw and impact crushers. The jaw crusher produced 85% coarse aggregates (fraction >4.8 mm), whereas the impact crusher produced 82% coarse aggregates. In both cases, the content of particles finer than 0.15 mm was less than 2% mass.

You can also mix crushed concrete with sand, water, Portland cement and aggregate to make new concrete that’s stronger and lighter than using concrete made of materials. After concrete passes through a crusher, workers separate the pieces by size and remove any scrap metal using strong electromagnets.

The aim of this paper is to evaluate the influence of the crushing process used to obtain recycled concrete aggregates on the performance of concrete made with those aggregates. Two crushing methods were considered: primary crushing, using a jaw crusher, and primary plus secondary crushing (PSC), using a jaw crusher followed by a hammer mill. Besides natural aggregates (NA), these two

Crush the concrete with a jaw crusher, impactor or cone crusher. 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
