This study investigates the effects of adding monofilament polypropylene fibers to concrete, focusing on its compressive and flexural strength. Results show that fiber doses up to 3.0 kg/m3 improve compressive strength by 10‒15% and flexural strength by 12‒20%. However, higher doses reduce mechanical properties due to uneven fiber distribution and lower mix workability. Using polypropylene fibers reduces the need for steel reinforcement, lowering the carbon footprint. This fiber-enhanced concrete is suitable for infrastructure applications, such as port quays, where durability and reduced maintenance are critical. Additionally, it offers cost benefits in projects without high dynamic load requirements.
