17/10/2019 · This paper presents an experimental study done on the structural behaviour of recycled aggregate concrete (RAC) beam specimens. Longitudinally reinforced beams with and without transverse reinforcement were tested under twopoint bending, at four replacement levels of recycled aggregates (30%, 50%, 70% and ). RAC beam specimens exhibited up to 30% higher ultimate .
