Optimization of Tensile Strength in PVA Fiber Reinforced Toughness-Concrete for Reinforcement Applications

PVA fiber reinforced toughness-concrete is widely used in masonry structure reinforcement due to its cost-effectiveness and excellent toughening effects. The tensile strength of the material significantly impacts the shear capacity of the masonry. This study systematically investigates the effects of fiber length and dosage on the uniaxial tensile behavior of PVA fiber reinforced toughness-concrete through finite element simulation and axial tensile tests. Additionally, the specific influence of fiber inclusion on the material’s tensile strength was analyzed through experiments and fitting calculations. The results indicate that optimizing the length and dosage of fibers can significantly enhance the tensile performance of the toughness-concrete. Consequently, this research has optimized the mix proportion of the toughness-concrete, thus balancing reinforcement effectiveness with material cost optimization. These achievements not only enhance the structural safety and durability of the reinforced masonry but also have significant practical implications for improving the shear carrying capacity of masonry structures.
