Q&A: Basics of recycled concrete
Recycled aggregate is waste material from demolished buildings or bridges, for example. When demolishing such structures, the waste needs to be sorted into wood, glass, etc. and concrete. This is called selective demolition, as the structure isn’t knocked down as a whole, but the materials are taken down selectively. Then, instead of dumping the concrete into a landfill, it is possible to

What is Recycled Aggregate Concrete?
Recycling concrete is a process of breaking, removing and crushing it from its current location. It is then re-created to be good as new. It is often the best option for concrete removal.

Performance of concrete made with aggregates recycled from precasting
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
