In Series I, using FNG instead of FNA resulted in a reduction in compressive strength by 12.8-49.8% and tensile strength by 14.5-44.6%. If the proportion of FNG exceeds 50%, compressive strength decreases by more than 24.5% and tensile strength by more than 27.5%. In Series II, replacing CNA with CRG reduced compressive and tensile strengths by 18.4-32.8% and 5.1-24.9%, respectively; exceeding 40% CRG results in a compressive strength reduction of more than 32.8% and a tensile strength reduction of more than 24.9%. In Series III, samples made with RCA, CNA, and 20% CRG showed a compressive strength decrease of 8.8-22% and a tensile strength decrease of 10.7-26%; RCA80 samples showed maximum reductions. In Series IV, replacing CNA with RCA resulted in compressive and tensile strength reductions of 15.4-34.7% and 13.9-24.3%, respectively; RCA80 samples again showed maximum reductions. Maximum stress unit deformation values (epsilon o) increased by 3-58.4% in Series I, 9-80% in Series II, 10-44.9% in Series III, and 9-32% in Series IV. Tensile toughness values showed the highest increase of 35.15% in the CRG40 sample and the lowest of 0.13% in the RCA40-20 sample. The use of glass aggregates in concrete is feasible, but exceeding certain ratios can significantly reduce strength. Concrete can effectively use waste glass as a partial substitute for cement, fine aggregates, or as a filler material, potentially enhancing compressive strength.eninfo:eu-repo/semantics/openAccessrecycled concrete aggregates (RCA)recycled glass aggregates (RGA)direct tensioneco-friendly concreteductilityMechanical-PropertiesColumnsArticle10.3390/buildings140929692-s2.0-85205219405
