    Large aggregates are economically advantageous in Portland cement and asphalt concrete, as they have less surface areaand, therefore, require less binder. However, large aggregate mixes, whether asphalt orPortland cement concrete, are harsher and more difficult to work into place. Hence, construction considerations, such as equipment capability,Recycled aggregate concrete from large-scale production to,Nov 30, 2020· This study shows that RCA has significant potential of using as substitution of natural aggregate in the production of concrete of 25 and 32 MPa compressive strength. Furthermore, RAC shows a higher rate of compressive strength development after 28 days of curing and results in comparable long-term compressive strength to conventional concrete.
