Massive pile-up of waste glass and extreme shortage of mineral resources have caused increasingly prominent environmental and social problems, while the development and application of pervious concrete (PC) are restricted by its low mechanical properties. This paper aims to investigate the feasibility of PC using waste glass powder (WGP) and waste glass sand (WGS), and conducts a synergistic optimization design for various performance indicators of PC. The study shows that the addition of WGP weakens the permeability and deformation performance of PC, while improving its mechanical properties. The optimal WGP content is 20 %. The addition of WGS reduces the permeability of PC while improving its deformation performance and mechanical properties. Based on comprehensive evaluation of PC performance indicators, the following recommendations are proposed: For coarse aggregates with particle sizes of 4.75–9.5 mm, 20 % WGP and 15 % WGS are recommended to achieve a flexural-tensile strength of 5.1 MPa (>4.5 MPa) and a permeability coefficient of 1.64 mm/s, which is suitable for medium-load pavements. For coarse aggregates with particle sizes of 9.5–16 mm, 20 % WGP and 15 %–20 % WGS are recommended to attain a flexural-tensile strength >3.5 MPa and a permeability coefficient >0.5 mm/s, which is applicable to light-load pavements. All parameters meet the technical requirements of the Specifications for Design of Highway Cement Concrete Pavement (JTG D40-2011). This study achieves efficient reuse of waste glass resources in PC, effectively enhances the mechanical properties of materials, promotes circular economy development in the PC industry, while reducing solid waste accumulation and mitigating environmental impacts from traditional building material production.

废玻璃制备透水混凝土的性能及孔隙结构的实验研究

废玻璃的大量堆积和矿产资源的极度短缺导致了日益突出的环境和社会问题，而透水混凝土 （PC） 的开发和应用则受到其低机械性能的限制。本文旨在探讨利用废玻璃粉 （WGP） 和废玻璃砂 （WGS） 进行 PC 的可行性，并针对 PC 的各项性能指标进行协同优化设计。研究表明，WGP 的加入削弱了 PC 的渗透性和变形性能，同时提高了其力学性能。最佳 WGP 含量为 20 %。WGS 的加入降低了 PC 的渗透性，同时提高了其变形性能和机械性能。基于对 PC 性能指标的综合评估，提出以下建议：对于粒径为 4.75-9.5 mm 的粗骨料，建议使用 20 % WGP 和 15 % WGS，以实现 5.1 MPa （>4.5 MPa） 的弯曲拉伸强度和 1.64 mm/s 的渗透系数，适用于中等负载路面。对于粒径为 9.5-16 mm 的粗骨料，建议使用 20 % WGP 和 15 %-20 % WGS，以获得弯曲拉伸强度 >3.5 MPa 和磁导系数 >0.5 mm/s，适用于轻载路面。所有参数均符合《公路水泥混凝土路面设计规范》（JTG D40-2011） 的技术要求。本研究实现了 PC 中废玻璃资源的有效再利用，有效增强了材料的机械性能，促进了 PC 行业的循环经济发展，同时减少了固体废物的积累并减轻了传统建材生产对环境的影响。
