Concrete is the most widely used construction material in urban development. As concrete-based infrastructure is replaced with new structures, an enormous amount of building waste is produced. By recycling concrete, the need for gravel mining, and the carbon footprint of manufacturing new concrete is reduced by 65 percent 1.
84 of states are recycling concrete as aggregate. While most states use RCA as base material, 22 use the recycled material as aggregate for new concrete pavements. Recycled concrete is easy to use.
