RECYCLED CONCRETE Cement

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. Even though concrete properties may differ slightly when using RCA, there are no special construction techniques required
