Abstract

The experimental study investigates the effect of using recycled demolition aggregate (RDA) on the flexural behaviour of reinforced concrete beams. The beams were 1400 mm long, 150 mm wide and 200 mm deep, with the same longitudinal and shear reinforcement. The replacement ratios of recycled demolition aggregate are 0 %, 25 %, 50 %, 75 %, and 100 % of the coarse aggregate weight. The results presented that the deflections of the beams were reduced by up to 15 % and 43 % of 75 % RDA and 100% RDA, respectively when compared to the control beam. Furthermore, at 100% RDA, ductility, stiffness, and toughness were reduced by approximately 24 %, 10 %, and 34 %, respectively. At the same stage of loading, RDA beams cracked faster than normal aggregate beams.
