Abstract

ABSTRACT 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.
含玻璃废料粗集料的钢筋混凝土结构性能
以前的大部分工作都是关于在混凝土中使用废玻璃作为骨料的力学性能,因此本研究的重点是使用废玻璃作为骨料部分替代品的钢筋混凝土(RC)梁的结构性能。本研究考察了废玻璃替代粗骨料的比例:0%(参考)、25%和50%对RC梁结构性能的影响。本工程采用6根梁(截面150 × 150毫米,跨度900毫米)。除了玻璃骨料含量对结构性能的影响外,还考虑了另一个参数,即纵向钢筋配筋率的影响(2Ø10 mm, ρ = 0.0083;2Ø16 mm, ρ = 0.0222)。含有废玻璃骨料(WGA)的梁与参考梁相比具有更强的延性和更小的刚度。与参考梁相比,含有WGA的梁具有良好的强度和令人满意的结构性能。
