Comparative Study on the Compressive Strength and Infiltration Rate of Pervious Concrete Reinforced with Pineapple Leaf and Snake Plant Fibers

This study examined the influence of Snake Plant fibers and Pineapple Leaf Fibers (PALF) on the compressive strength and infiltration rate of pervious concrete, with emphasis on sustainability and alignment with the United Nations Sustainable Development Goals (SDGs). Compressive strength was tested at 7-, 14-, and 28-days following ASTM C39, while infiltration rate was assessed in accordance with ASTM C1701. Results showed that Snake Plant fibers provided modest strength improvement, with the 0.3% mix achieving 8.93 MPa at 28 days, slightly higher than the control. The most notable effect was on permeability, where the 0.2% mix attained the highest infiltration rate of 0.0203 m/s, highlighting its suitability for drainage-critical applications. In contrast, PALF demonstrated a stronger influence on strength development, with the 1.0% PALF mix reaching 21.02 MPa at 28 days, outperforming the control at 16.24 MPa. Although PALF slightly reduced infiltration compared to the control, its values remained within the standard range for pervious concrete. Statistical analysis (p > 0.05) indicated no significant differences between control and fiber-reinforced mixes, though consistent performance trends were observed. Overall, the findings suggest that PALF is more effective for enhancing compressive strength, while Snake Plant fibers are more effective for improving infiltration. The use of these natural fibers not only improves pervious concrete performance but also promotes sustainability by utilizing agricultural waste. This aligns with SDG 9 (Industry, Innovation, and Infrastructure), SDG 11 (Sustainable Cities and Communities), and SDG 12 (Responsible Consumption and Production), contributing to eco-friendly construction materials and resilient urban infrastructure.
