Abstract

To address the environmental issues arising from the growing scarcity of natural fine aggregates (NFA) and landfilling of waste glass, research is being conducted globally to utilize waste glass as a sustainable fine aggregate. However, contradictory results have been obtained regarding the effect of the type of waste glass and the physical properties of waste glass fine aggregate (GFA) on concrete, making it challenging to promote the use of GFA in concrete. Therefore, to promote the use of GFA in concrete, it is necessary to examine it under field conditions, such as mass-production processes or real-scale concrete applications. This study introduced a mass-production process for GFA, and the effect of mass-produced GFA on mortar was evaluated. The fine aggregate properties (particle aspect ratio, crushing rate, and solubility) of the GFA and the effects of color, content, and particle size on the mortar properties (compressive strength, flexural strength, and ASR expansion behavior) were analyzed, along with the results reported in previous studies. Consequently, the high aspect ratio and microcracks in the particles of mass-produced GFA led to an increase in the strength reduction and ASR expansion of the mortar. These effects appear to be particularly severe for transparent GFA. Overall, this study proposed the content of GFA within 20% or the replacement of fine particles (< 500 μm) in NFA as a condition for sustainable fine aggregate.

将大量生产的废玻璃用作砂浆可持续细骨料的条件调查
为解决天然细骨料(NFA)日益稀缺和废玻璃填埋带来的环境问题,全球正在开展研究,将废玻璃作为一种可持续的细骨料加以利用。然而,关于废玻璃的类型和废玻璃细骨料(GFA)的物理性质对混凝土的影响,研究结果相互矛盾,这使得在混凝土中推广使用 GFA 变得十分困难。因此,要在混凝土中推广使用 GFA,有必要在实地条件下进行研究,如大规模生产工艺或实际规模的混凝土应用。本研究引入了 GFA 的大规模生产工艺,并评估了大规模生产的 GFA 对砂浆的影响。分析了 GFA 的细骨料特性(颗粒长径比、压碎率和溶解度)以及颜色、含量和颗粒大小对砂浆特性(抗压强度、抗折强度和 ASR 膨胀行为)的影响,并参考了之前研究的结果。结果表明,大规模生产的 GFA 颗粒中的高纵横比和微裂缝导致砂浆的强度降低和 ASR 膨胀增加。这些影响似乎对透明 GFA 尤为严重。总之,本研究建议将 GFA 含量控制在 20% 以内,或将细颗粒(< 500 μm)替换为 NFA 作为可持续细骨料的条件。
