Abstract
•Recycled glass fiber reinforced polymer (GFRP) was used as reinforcement in the mortar.•Fiber-like GFRP shapes replaced fine aggregate in mortar.•Aspect ratios were compared in terms of toughness and strength.•Volumetric percentages of 1 and 3 showed the most successful results.
Glass fiber reinforced polymer (GFRP) panels from retired wind turbines were recycled into discrete structural elements in mortar. Based on 7-day testing, out of Powder, Small, Medium, and Large fiber size groups, the Large group was identified as the optimum size due to the highest modulus of rupture (MR) and toughness index (TI) while maintaining comparable compressive strength (f’c) relative to control. Implementing the Large group at 1, 3, and 5% replacement of sand resulted in 5, 25 and 35% increases in 90-day MR with significant increases in TI and minimal reductions in f’c and no expansion due to alkali-silica reaction.
