Long term performance of recycled concrete beams with different water–cement ratio and recycled aggregatereplacement rate

Jingwei YING; Feiming SU; Shuangren CHEN

Frontiers of Structural and Civil Engineering 2022, Volume 16, Issue 3, Pages 302-315 doi: 10.1007/s11709-022-0803-7

Abstract: The purpose of this study is to reveal the service performance of recycled aggregate concrete (RAC) componentsfor different values of water−cement ratio and replacement rate of recycled coarse aggregate (RCA).Generally, the concrete strength decreases with the increase of the replacement rate of RCA, in orderto meet the strength requirements when changing the replacement rate of RCA, it is necessary to changerate.
