Structural behavior of reinforced concrete incorporating glass waste as coarse aggregate

Structural behavior of reinforced concrete incorporating glass waste as coarse aggregate Most of the previous work related to using waste glass as aggregate in concrete focused on mechanical properties, so this investigation focused on the structural behavior of reinforced concrete (RC) beams incorporating waste glass as a partial replacement of aggregate. This research investigated the influence of waste glass as a replacement for coarse aggregate in the following percentages: 0% (reference), 25% and 50%, on the structural behavior of RC beams. This work uses six beams (cross-section 150 × 150 mm and span length of 900 mm). In addition to the effect of glass aggregate content on structural behavior, another parameter was considered, which is the effect of longitudinal steel reinforcement ratio (2Ø10 mm, ρ = 0.0083; 2Ø16 mm, ρ = 0.0222). The beams containing waste glass aggregate (WGA) showed a more ductile behavior and were less stiff compared to reference beams. Beams containing WGA showed good strength and satisfactory structural performance compared with the reference beam. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Structural Integrity and Maintenance Taylor & Francis
