Recycled Concrete Aggregate. According to the American Concrete Pavement Association, recycling of concrete pavement is a relatively simple process. It involves breaking, removing and crushing concrete from an existing pavement into a material with a specified size and quality. Crushed concrete may be reused as an aggregate in new Portland ...

Recycled concrete aggregate, also known as RCA, is an extremely popular replacement for natural stone aggregates. RCA is made up of old concrete from sidewalks, pavements, curbing and building slabs by processing the material through a crusher. In comparison to other fills, RCA is more economical and performs equally as well.

The produced coarse recycled concrete aggregate is sent to a rotary kiln for calcination, which can burn the combustible impurities into ashes. The calcined aggregate is then ground into powder by ball mills and Raymond mills. The calcination treatment method removes the combustibles in the recycled concrete aggregate and reduces the moisture ...

Concrete aggregate is the inert filler that compromises 60% to 80% of concrete mixes. Aggregate is mixed with cement to create concrete. Part of the aggregate used for mixing concrete can be recycled concrete powder and gravel. Recycled concrete is not best suited for certain types of construction requiring the highest possible strength.

In this paper, a comprehensive literature review was conducted on the utilization of recycled concrete aggregate (RCA), which is the dominant construction and demolition waste material, in base and subbase layers and its comparison with natural aggregate (NA).
