Abstract | Glass, a crucial material in modern society, poses environmental challenges during production and disposal. Despite the potential of recycling, the global glass recycling rate is low due to sorting and cleaning costs (Guo et al., 2020). Integrating waste glass into composite materials like concrete could be a solution. However, the Alkali-Silica Reaction (ASR) in previous studies has shown long-term issues with cracking and concrete weakening (Pike and Hubbard, 1957). Recent research indicates that partially replacing Ordinary Portland Cement (OPC) with fly ash can mitigate ASR due to its low CaO content, resulting in lower alkalinity (Kim et al., 2015). This research investigates the compressive strength of mortar by substituting river sand with crushed waste glass, considering different percentages of Glass Fine Aggregate (GFA) ranging from 0% to 100% in 20% intervals. The study also considers various GFA sizes (< 4.75 mm, 1.18 mm–4.75 mm,< 1.18 mm) and testing periods (28 days and 91 days), all while incorporating 20% fly ash into the mix. The goal is to gain a comprehensive understanding of fly ash-infused GFA mortar. |
