Abstract：
Improper waste management is causing global environmental problems. Waste glass may have adverse impacts on the ecosystem. While a substantial amount of soda-lime glass bottle (SGB) undergoes recycling to create new glass items, a significant volume still ends up in landfills. Therefore, the aim of this study was to explore the potential use of SGB in foamed concrete (FC) production as an aggregate replacement. SGB was substituted for sand in different weight fractions, ranging from 5 to 50%. The fresh state, mechanical, thermal, pore structure, and transport properties were examined. The findings showed a significant enhancement in the FC\'s mechanical properties when SGB replaced 20% of sand. The compressive, flexural, and splitting tensile strengths exhibited a rise of up to 17.7, 39.4, and 43.8%, respectively. The findings also demonstrated that the addition of SGB improved the thermal conductivity, sorptivity, water absorption, and porosity. The scanning electron microscopy analysis indicated that the inclusion of 20% SGB caused a substantial decrease in void diameter and enhanced its uniformity. A comparison was made between the experimental data and predictions of the mechanical properties using various models of international standards, such as IS 456, ACI 318, NZS-3101, EC-02, AS 3600, and CEB-FIB, along with several references in the literature. The findings implied a strong correlation between the strength properties. The outcomes of this research offer valuable insights into both the possible advantages and constraints of using SGB in FC. Furthermore, this extensive laboratory investigation may serve as a guideline for future study and aid in the advancement of greener and more environmentally friendly FC alternatives.
摘要：
废物管理不当正在引起全球环境问题。废弃玻璃可能会对生态系统产生不利影响。虽然大量的钠钙玻璃瓶（SGB）经过回收以制造新的玻璃制品，大量的垃圾最终仍被填埋。因此,这项研究的目的是探索SGB在泡沫混凝土（FC）生产中作为骨料替代品的潜在用途。SGB代替了不同重量分数的沙子，从5%到50%不等。新鲜的状态，机械,热,孔隙结构,并检查了传输特性。研究结果表明，当SGB替代20％的沙子时，FC的机械性能显着提高。压缩，弯曲,劈裂抗拉强度分别提高了17.7%、39.4%和43.8%，分别。研究结果还表明，SGB的加入提高了热导率，吸着性,吸水,和孔隙度。扫描电子显微镜分析表明，包含20％的SGB会导致空隙直径显着降低并增强其均匀性。使用各种国际标准模型对实验数据和机械性能的预测进行了比较，如IS456、ACI318、NZS-3101、EC-02、AS3600和CEB-FIB，以及文献中的一些参考文献。这些发现暗示了强度特性之间的强相关性。这项研究的结果为在FC中使用SGB的可能优势和限制提供了有价值的见解。此外，这项广泛的实验室调查可以作为未来研究的指南，并有助于开发更绿色，更环保的FC替代品。
