Özet

Growing emphasis on sustainability and decarbonization has intensified efforts to reduce cement consumption by developing different SCMs and maximizing the utilization of industrial byproducts and wastes. Among these, the boron mining waste, generated during production, processing, and supply chain in Turkey, which holds three-fourths of the world's boron reserves, poses environmental concerns and significant transportation and storage costs. In contrast to previous studies, this research used refined, grounded boron waste pulp obtained during the final stage of the boron production process involving centrifugation and crystallization. The study examined the performance of GGBFS-based alkali-activated composites (AACs) incorporating different proportions of boron waste (0 %, 3 %, 6 %, 9 %, 12 %, and 15 %) and activated with NaOH solutions of varying strengths (5 M, 10 M, and 15 M). The performance of ACC mixes containing varying dosages of boron waste and activated with NaOH solutions of different molarities was investigated by evaluating mechanical properties (compressive and flexural strength), ultrasonic pulse velocity, and high temperature resistance, with the aid of SEM and XRD analysis. The results showed that incorporating boron waste up to 9 % in composites activated with 10 M NaOH yielded the most favourable mechanical and thermal resistance properties.
