Abstrakt: This study examines the effects of recycled aggregate and waste glass powder on concrete's fresh and mechanical characteristics. This investigation used recycled aggregate and waste glass powder content of 0%, 10%, 20%, 30%, 40%, and 50% to partially replace coarse and fine aggregate, respectively. The fresh concrete properties were assessed by conducting tests for slump, density, and compacting factor on six different concrete mix proportions. Additionally, we evaluated the concrete's mechanical properties, such as its flexural, splitting tensile, and compressive strength, on the 7th, 14th, and 28th days of curing. The study revealed that while using recycled aggregate reduced the fresh properties of concrete, adding waste glass powder actually improved the fresh concrete properties. Furthermore, the inclusion of recycled aggregate and glass powder significantly enhanced the mechanical properties of the concrete compared to the experimental mixture. In general, the 30% recycled aggregate and waste glass powder mixture had a big effect on the flexural, split tensile, and compressive strengths of concrete that had other proportions.
