Samples of concrete containing varying percentages of waste glass wool by total concrete volume (0%, 1%, 2%, 3%, 4%, and 5%) were tested after exposure to a range of temperatures: 24 °C, 400 °C, 600 °C, and 800 °C. Several tests, including compressive strength (CS), splitting tensile strength (STS), and flexural strength (FS), were then performed on the samples in the laboratory following the completion of elevated temperature. The results showed that glass wool waste material reduces the concrete CS. Conversely, experiments have shown that samples STS and FS, increase proportionally with the amount of waste glass wool. Accordingly, the concrete compressive strength decreased by 4.26%, 7.84%, 11.87%, 14.24%, and 17.27% when the mixing ratio was increased from 1% to 5%. On the other hand, by increasing the mixing ratio from 1% to 5%, concrete STS and FS were enhanced by 9.61%; 15.19%; 27.70%; 36.58%; and 60.41% and 16.91%; 29.99%; 35.73%; 45.45%; and 59.45%, respectively. FE-SEM and EDX analysis was also included. Furthermore, equations were developed to estimate the capacities of concrete, with waste glass wool, after exposure to elevated temperatures. Taguchi analysis revealed that temperature is the most critical factor affecting mechanical performance, while the addition of waste glass wool contributed to strength retention at elevated temperatures. ANOVA confirmed the statistical significance of both temperature and waste glass wool’s contribution, reinforcing their combined role in producing sustainable concrete with improved high-temperature resistance. The addition of waste glass wool to concrete recycles waste glass wool and minimizes the need for new raw materials and waste disposal requirements. According to the ratio and distribution above, adding modest quantities of glass wool may lighten concrete without affecting its strength.  \nKeywords Waste glass wool, Elevated temperature, Compressive strength, Splitting tensile strength, Flexural strength  \nConcrete, with its remarkable versatility, durability, and adaptability, stands as the most widely used construction material in modern infrastructure and serves as a cornerstone of global development through its extensive use in buildings, roads, bridges, and various other structures1,2. As a consequence of growing environmental consciousness, the concrete industry is under pressure to reduce the use of natural resources. However, the production of traditional concrete creates serious environmental impacts largely due to the intensive use of natural resources and energy3. The growing need to protect natural resources, effectively manage industrial and construction waste, and reduce environmental pollution has encouraged the use of industrial and construction waste as a sustainable building material4,5.
