<br/><br/> This study examines the effects of polypropylene fiber (PPF) additives on concrete cylinder blocks, specifically compressive strength, water absorption, and specific gravity. Concrete samples with o%, 5%, and 15% PPF were tested, and results analyzed using the Kruskal-Wallis test showed no statistically significant difference among the groups. However,<br/>increasing PPF content led to higher water absorption, reduced weight, and a slight decrease in compressive strength. None of the samples met the Department of Public Works and Highways (DPWH) standard of 3000 psi for compressive strength, and all exceeded the 3% water absorption limit for durability. While PPF-modified concrete offers benefits like lower density and plastic waste repurposing, its mechanical properties may limit its use in load-bearing structures.
