This research therefore explores the impact of incorporation of polyester fiber into concrete with an aim of identifying the optimal fiber to concrete ratio that maximizes strength and durability. The study involved a series of laboratory experiments where the concrete pavers were cast with varying proportions of fiber content while optimizing with 0.10% to 0.20% of fiber with a diameter of 0.02mm and 12mm length. The major performance indicators assessed in this study were load-bearing capacity, crack resistance, and water absorption rates. Comparative analysis was conducted against conventional concrete pavers to evaluate improvements in structural integrity and service life. The results indicate that the optimum polyester fiber ratio for reinforced concrete pavers is 0.5% by weight of cement. At this ratio, the pavers exhibited a 20% increase in compressive strength and a 15% improvement in flexural strength compared to non-reinforced pavers. Additionally, there was a reduction in surface cracking and water permeability thus evidence of achieving durability. Therefore, the scientific findings of this study prove valuable insights into the practical application of fiber reinforced concrete as a paving solution. For more durable and resilient pavement structures especially concrete pavers, it is more ideal to use fiber reinforcement at the obtained optimum ratio (0.16%).enThesis
