Abstract Ordinary Portland cement (OPC) production raises environmental concerns, driving research into sustainable alternatives like alkali‐activated geopolymer composites (GPC). This study examines the mechanical, durability, and thermal properties of ternary GPCs made with 85% fly ash, 15% metakaolin, 5% silica fume. Steel, basalt, carbon (CF) fibers were added in varying amounts to assess their impact. Waste marble powder (WMP) quartz aggregate (QA) served as fillers enhance strength durability. cured at 90°C for 16 h tested compressive strength, flexural dry unit weight, porosity, water absorption, sorptivity, freeze–thaw resistance, high‐temperature resistance 200, 400, 800°C. Fiber reinforcement significantly improved mechanical properties, CF showing best performance. The highest (40.23 MPa, +21.49%) was recorded 1.5% mix. CF‐reinforced mixtures also had lowest porosity (6.76%) absorption (6.55%), improving At high temperatures, all gained 200°C due matrix densification. Strength loss 800°C ranged from 10.1% 20.6%, exhibiting resistance. Freeze–thaw tests showed that (12.7%), confirming durability benefits. These findings demonstrate hybrid fiber enhances performance composites, making them suitable structural applications requiring superior stability.

Abstract This study investigates the effects of reclaimed asphalt pavement (RAP) aggregates and silica fume (SF) on mechanical, durability, microstructural properties fly ash (FA)‐based geopolymer composites (GC) under varying curing conditions. GCs were prepared with RAP contents 0%, 15%, 30%, 60% as replacements for river aggregate (RA) partial replacement FA by 15% SF. Samples cured at 60°C 90°C, their performance was evaluated through compressive flexural strength tests, freeze–thaw (F‐T) resistance, high‐temperature exposure, sorptivity, porosity, analysis. The results reveal that substituting RA demonstrated optimal content enhancing strength, increases 33.64% 8.04% 90°C. At 30% RAP, improvements smaller (7.36% 7.37% 90°C), while led to reductions 0.97% 8.12% respectively. mixture containing 100% a best performance, exhibiting lowest loss 750°C. after 50 F‐T cycles observed in 90°C FA. Mixtures exhibited cycles, demonstrating enhanced durability. superior incorporation compared reference without irrespective temperature. highest resistance elevated temperatures, minimal However, increasing greater deterioration due thermal degradation bitumen‐coated aggregates. Replacing SF significantly reduced causing over 90%
