Abstract
The production of conventional reinforced concrete is encountered with reduced ductility, reduced deflections before failure and increased crack widths. The construction industry is currently focused on improved knowledge of reinforced concrete beams, primarily on using alternative materials to produce concrete that can improve concrete properties and produce eco-friendly concrete. This paper studies the flexural and shear performance of reinforced concrete beams modified with 1.5% polyethylene terephthalate (PET) fibres and 5% blue gumwood ash (BGWA) replacing cement. Four beams were subjected to flexural failure testing, while the other 4 beams were subjected to shear failure testing. The behaviour of the tested beams was assessed based on cracking behaviour, ductility, load-deflection responses, load-strain responses, ultimate loads, flexural behaviour and shear behaviour. For modified concrete beams with and without shear reinforcement, the ductility increased by 4.8% and 6.3%, respectively, compared with control concrete beams. The combination of PET fibres and BGWA in concrete beams with shear reinforcement increased the number of cracks, ultimate loads, and ultimate deflections compared with control concrete beams. Moreover, flexural and shear capacities increased for reinforced concrete beams containing PET fibres and BGWA than control concrete. Eventually, a reinforced concrete beam modified with PET fibres and BGWA was suggested to be a promising candidate for structural members exposed to seismic loads. The combination of PET fibres and BGWA in concrete could provide a new concrete composite with improved ductility, increased flexural capacity, enhanced shear capacity and decreased crack width.
