This study investigates the use of Waste Glass Powder (WGP) as a proportional replacement for cement in sustainable concrete production. In addition, changes in the bending capacity of the Reinforced Concrete (RC) Beams were examined by adding WGP at different rates (0%, 10%, 20%, 30%) to RC Beams with different steel reinforcement ratios (ρ = 0.0077 i.e. Φ8, ρ = 0.0121 i.e. Φ10, ρ = 0.0174 i.e. Φ12). To pursue this goal, 12 test specimens were evaluated and then confirmed to explore the bending productivity. The amount of longitudinal bar section area and WGP proportion were chosen as the key parameters. For this aim, experimental and analytical investigations were carried out by replacing cement with WGP in weight ratios of 10%, 20%, and 30% and considering three different longitudinal reinforcements (ρ = 0.0077 i.e. Φ8, Φ10, Φ12). The test results showed that tension reinforcement section area and WGP proportion dimensions had dissimilar rupture and flexure effects on RC Beams. Furthermore, investigational tests are confirmed with the help of the Digital Imagining Method, and the image processing method was used to identify the cracks/microcracks in RC Beams. Consequently, it is observed that each WGP ratio in the concrete combination has dissimilar bending and rupture properties on the RC Beams for experimental tests-10% of partial replacement of cement. It was found that a WGP ratio of more than 10% can significantly reduce the bending capacity of RC Beams. When the experimental test beams were compared with the analytical results, it was observed that the experimental results and analytical calculations are in agreement.
本研究探讨了在可持续混凝土生产中使用废玻璃粉（WGP）按比例替代水泥的情况。此外，通过以不同比例（0%、10%、20%、30%）向不同配筋率（ρ = 0.0077即Φ8、ρ = 0.0121即Φ10、ρ = 0.0174即Φ12）的钢筋混凝土（RC）梁中添加WGP，研究了RC梁抗弯能力的变化。为实现这一目标，评估了12个试验试件，然后进行验证以探究抗弯性能。纵筋截面面积和WGP比例被选为关键参数。为此，通过用WGP以10%、20%和30%的重量比替代水泥，并考虑三种不同的纵筋配筋（ρ = 0.0077即Φ8、Φ10、Φ12），开展了试验研究和分析研究。试验结果表明，受拉钢筋截面面积和WGP比例尺寸对RC梁具有不同的破坏和弯曲影响。此外，借助数字成像方法对试验进行了验证，并使用图像处理方法识别RC梁中的裂缝/微裂缝。因此，观察到在试验测试中，混凝土组合中每个WGP比例对RC梁具有不同的弯曲和破坏性能——水泥部分替代率为10%。结果发现，WGP比例超过10%会显著降低RC梁的抗弯能力。当将试验测试梁与分析结果进行比较时，发现试验结果与分析计算结果一致。
