Özet:

 This study examines the substantial enhancement in the performance of alkali-activated composites AACs produced from a distinctive combination of metazeolite MZ and slag S, reinforced with synthetic fibers, and augmented with aluminum sludge AS and recycled concrete aggregate RCA. The composites were subjected to activation through the use of a specific sodium hydroxide NaOH and sodium silicate Na₂SiO₃ blend in a 2:1 ratio, with an activator-to-binder ratio of 0.95. Through a process of experimentation, the research team identified an optimal mix by varying the molarities of sodium hydroxide NaOH between 8M and 14M and the ratios of metazeolite to slag between 25 and 100. The aforementioned mixture, comprising 50 MZ and 50 S, was activated with 12M NaOH and enhanced with 30 aluminum sludge, exhibiting remarkable strength characteristics. Furthermore, the incorporation of synthetic fibres, including polyethylene PEF, polyamide PAF, and basalt fibers BF, resulted in a notable enhancement of the materials performance. It is noteworthy that the addition of basalt fibers at a concentration of 0.5 resulted in a 7 increase in compressive strength and a 24 improvement in flexural strength. This pioneering research illuminates the transformative potential of MZ-S-based AACs, particularly when combined with AS and BF, paving the way for the development of sustainable construction materials that meet contemporary performance and environmental standards.
