Recycled aggregates (RA) from construction and demolition waste (CDW) instead of natural aggregates (NA) were analysed in the manufacture of new eco-friendly concrete. Fine (FRA) and coarse (CRA) recycled aggregates were used in different percentages as substitutes of natural sand and gravel, respectively. The results revealed that the use of …

The journey of concrete recycling begins with the collection of concrete waste from various sources, such as construction sites, demolition projects, and excess materials from concrete production. This waste, comprising old concrete slabs, pipes, bricks, blocks, and other forms of concrete rubble, is transported to recycling facilities.
