Abstract/Executive Summary
Despite the ecological and socio-economic posed by non-endemic species such as water hyacinths (Eicchornia Crassipes) and Asian green mussel shells (Perna viridis) in the Philippines, this study explores their potential application as fiber-reinforcement and aggregate replacement in the fabrication of enhanced, eco-friendly Fiber-Reinforced Concrete Boards (FRCB) across varying mixture ratios: Negative Control (0:0:100), Experimental Group 1 (5:25:70). Experimental Group 2 (10:20:70) and Experimental Group 3 (15:15:70). Flexural strength and durability were the main parameters for the study, which was assessed using a Universal Testing Machine (ASTM C1185-03) and water absorption methods (ASTM C642-06), respectively. Results were then statistically analyzed through descriptive analysis (mean and standard deviation) and inferential statistical analysis using one-way ANOVA and Tukey’s HSD tests, with triangulation across Microsoft Excel, and SPSS software, to validate significant differences between groups. Results showed that the 10:20:70 (WHF:MSA:cement) mix (Exp. 2) achieved the highest flexural strength at 25.016 MPa. One-way ANOVA confirmed a statistically significant difference in strength (P = 0.010; F = 7.49), indicating the effectiveness of a balanced WHF-MSA ratio. Durability testing revealed the control group (0:0:100) had the lowest water absorption at 6.81%, with ANOVA also confirming significant differences in durability among groups. While all experimental groups absorbed more moisture than the control, the 10:20:70 mix provided the best balance of strength and durability. The findings align with previous studies on WHF and MSA used separately, supporting their combined potential in sustainable cement composites. However, performance variability across formulations suggests further optimization is needed to enhance FRCB properties.
