Flexural Behavior of Corroded Reinforced Recycled Aggregate Concrete Beams
Advances in Materials Science and Engineering, 2018 Recycling concrete not only reduces the use of virgin aggregate but also decreases the pressure on landfills. As a result, recycled coarse aggregate (RCA) is extensively recommended for new construction projects.
