The use of waste glass in concrete can bring significant economic and environmental benefits due to reduction of landfills and demand for natural aggregates. This paper presents a comprehensive investigation on the feasibility of using high volume of waste glass as fine aggregate in self‐compacting concrete (SCC). A detailed investigation on fresh behavior of mixtures was performed by evaluating filling ability, stability, passing ability, and viscosity of SCC mixtures. Compressive strength and electrical resistivity experiments and scanning electron microscope analysis were also performed to investigate the strength and durability of the concrete mixtures. Furthermore, alkali silica reaction (ASR) potential of different size ranges of the used glass was assessed. The obtained results revealed that excessive bleeding and segregation and deleterious ASR expansion are possible challenges of incorporating fine glass aggregates in SCC. Interestingly, there was no evidence that glass has a considerable impact on the mechanical performance of concrete whereas it increased the electrical resistivity of concrete. Utilizing high volume of waste glass in SCC up to 600 kg/m³ became feasible when a part of portland cement was substituted with zeolite.

解决含沸石量大的废玻璃骨料的自密实混凝土的问题

由于减少了垃圾掩埋场和对天然骨料的需求，在混凝土中使用废玻璃可带来重大的经济和环境效益。本文对在自密实混凝土（SCC）中使用大量废玻璃作为细骨料的可行性进行了全面研究。通过评估SCC混合物的填充能力，稳定性，通过能力和粘度，对混合物的新鲜行为进行了详细研究。还进行了抗压强度和电阻率实验以及扫描电子显微镜分析，以研究混凝土混合物的强度和耐久性。此外，评估了所用玻璃的不同尺寸范围的碱二氧化硅反应（ASR）电位。获得的结果表明，过多的渗色和偏析以及有害的ASR膨胀是在SCC中掺入细玻璃骨料的可能挑战。有趣的是，没有证据表明玻璃对混凝土的机械性能有很大影响，而玻璃却增加了混凝土的电阻率。在SCC中利用大量废玻璃达到600 kg / m当一部分波特兰水泥用沸石代替时，图³变得可行。
