摘要

随着建筑行业向可持续发展的转变,再生玻璃正在成为改善土壤特性和增强混凝土性能的有前途的替代材料。本综述综合了最近15个案例研究的结果,表明在建筑材料中使用再生玻璃不仅可以减少垃圾填埋,节约自然资源,还可以提高结构和环境性能。通过将20% %的再生玻璃作为混凝土中传统骨料的替代品,抗压强度可提高15% %,而碳排放量可减少约30% %。使用细磨玻璃粉作为补充胶凝材料有助于提高耐久性和耐化学性,降低碱-硅反应的风险。在岩土工程应用中,再生玻璃在稳定土壤、增强承载能力、降低渗透性和提高对环境压力的恢复能力方面显示出巨大的潜力。实验室研究表明,掺有10-30 %玻璃颗粒的土壤抗剪强度提高,沉降减少,使其成为可持续道路建设和基础材料的可行选择。本文还比较分析了不同的玻璃加工方法,包括粒径变化和表面处理,以及它们对混凝土和土壤力学和化学性质的影响。除了环境优势,回收玻璃集成的经济效益是可观的。使用当地采购的再生玻璃可以降低材料成本,减少运输排放,并支持在回收和建筑行业创造就业机会。通过促进循环经济原则,减少能源消耗,减少温室气体排放,采用再生玻璃为更有弹性和更环保的建筑环境提供了一条可行的途径。这篇综述强调了需要进一步的研究和政策支持,以最大限度地发挥再生玻璃在可持续建筑中的潜力。

Enhancing environmental benefits through recycling glass to improve soil properties and concrete
As the construction industry shifts towards sustainability, recycled glass is emerging as a promising alternative material for improving soil properties and enhancing concrete performance. This review synthesizes findings from 15 recent case studies, demonstrating that the integration of recycled glass in construction materials not only reduces landfill waste and conserves natural resources but also enhances structural and environmental performance. By incorporating 20 % recycled glass as a replacement for traditional aggregates in concrete, compressive strength can increase by up to 15 %, while carbon emissions are reduced by approximately 30 %. The use of finely ground glass powder as a supplementary cementitious material contributes to improved durability and chemical resistance, reducing the risk of alkali-silica reaction. In geotechnical applications, recycled glass has shown significant potential in soil stabilization, enhancing load-bearing capacity, reducing permeability, and improving resilience to environmental stressors. Laboratory studies indicate that soil mixed with 10–30 % glass particles exhibits improved shear strength and reduced settlement, making it a viable alternative for sustainable road construction and foundation materials. The review also provides a comparative analysis of different glass processing methods, including particle size variation and surface treatment, and their effects on the mechanical and chemical properties of both concrete and soil. Beyond environmental advantages, the economic benefits of recycled glass integration are substantial. The use of locally sourced recycled glass reduces material costs, lowers transportation emissions, and supports job creation in the recycling and construction industries. By promoting circular economy principles, reducing energy consumption, and mitigating greenhouse gas emissions, the adoption of recycled glass presents a viable pathway toward a more resilient and eco-friendlier built environment. This review highlights the need for further research and policy support to maximize the potential of recycled glass in sustainable construction.
