چکیده مقاله:
Every day several tons of glass are disposed of as waste. Glass waste, as a non-degradable waste, causes many environmental problems. Using glass waste powder in concrete as a partial substitute for cement has notable effects on reducing environmental pollutants, energy consumption, and concrete production costs. In this study, the impact of using waste glass powder in levels of ۵, ۱۰, ۱۵, and ۲۰ wt% as a substitute for cement on the mechanical properties of concrete was evaluated. Chemical analysis of glass and cement samples was determined using X-ray fluorescence (XRF). The flexural and compressive strength of the samples were measured according to ISO ۶۷۹, Methods of testing cement–Determination of strength, in ۳, ۷, ۲۸, and ۹۰ days. The compressive strength test results showed that the strength of concrete increases by the amount of used glass powder in the concrete composition. The highest value of compressive strength was obtained by the sample with ۱۵ wt% of glass powder.
