In recent years, there has been a significant increase in studies aimed at utilizing waste materials in the production of sustainable building materials. In this context, geopolymer concrete, an environmentally friendly and durable alternative, has emerged as a promising construction material for the reuse of waste materials. This study investigates the potential use of barite waste in the production of geopolymer concrete. In the experimental studies, the water/binder ratio, sodium silicate, sodium hydroxide, and ground granulated blast furnace slag were kept constant, while barite waste was added at rates of 10%, 20%, and 30% in place of the sand used as aggregate. The effects of different proportions of barite waste on the flexural and compressive strength of geopolymer concrete were examined. The results revealed that an increase in barite content provided a partial improvement in mechanical properties. The highest compressive strength was recorded as 67.10 MPa in the sample containing 20% barite. These findings suggest that barite waste can be considered a potential additive material in the development of environmentally friendly and durable construction materials. Accordingly, it is recommended that further advanced studies be conducted to explore different combinations incorporating barite waste.
