N2 - This study investigates the effect of incorporating fibrous by-products of flax processing (flax tow) into coal fly ash-based geopolymer mortars at dosages of 0.25–1.0 wt%. The primary focus is on tensile strength, thermal conductivity and abrasion resistance, with additional assessment of dry density, ultrasonic pulse velocity, and microstructural features. The lowest abrasion mass loss (0.3 kg/m²) was recorded at 0.5 % flax tow, corresponding to a 36 % increase in abrasion resistance compared to the control. The highest thermal conductivity reduction (12 %) and tensile strength improvement (18 %) occurred at 1.0 % flax tow. Within the experiment limits, flax tow addition yielded simultaneous improvements in mechanical performance, thermal insulation, and wear resistance, comparable to or exceeding those of high-grade natural and synthetic fibers. The results demonstrate the feasibility of using flax tow as a cost-effective reinforcement in geopolymers, offering a sustainable pathway for high-performance building materials.
