In particular, disposing of waste glass powder (WGP) from the glass industry requires significant storage capacity. Therefore, utilizing WGP as a raw material in construction is both an environmentally and economically viable solution. This study examined the workability, flexural strength, compressive strength, and splitting tensile strength of glass fiber-reinforced mortars containing WGP. A face-centered composite design was used to determine 13 test points. The fiber ratio was selected at 0%, 0.3%, and 0.6% by weight of the mixture, while WGP substitution levels were 0%, 7.5%, and 15% by weight of cement. The results indicate that adding glass fiber and WGP reduces flow value, flexural strength, compressive strength, and splitting tensile strength. However, at higher glass fiber ratios, the negative effect of WGP on flow value and compressive strength is less pronounced. The R2 values for flow value, flexural strength, compressive strength, and splitting tensile strength were 0.9983, 0.9586, 0.9069, and 0.8526, respectively, indicating a strong correlation between the tested parameters and the predictive model.}, number={2}, publisher={Nigde Omer Halisdemir University}
