| dc.description.abstract | This study investigates the effect of varying sawdust reinforcement volumes on the physical and mechanical properties of Portland cement composites. Sawdust from a local sawmill in Moro, Kwara, Nigeria, was incorporated into cement composites at volume fractions from 40% to 90%. Composites samples were produced for physical, mechanical and microstructural characterizations. Results showed that water absorption increased with higher sawdust content, peaking at 41.78% for 90% sawdust composite, and bulk density also rose, reaching a maximum of 193.33 g/m³ at 90%. Apparent void volume generally decreased with increasing sawdust content. Optimal mechanical properties were observed at 60% sawdust content, with the highest compressive strength of 20.32 MPa, flexural strength of 8.36 MPa, and fracture toughness of 0.85 MPa.m, while hardness decreased with increasing sawdust, peaking at 42.99 HRBS at 40% sawdust. Microstructural analysis using scanning electron microscopy (SEM) revealed a uniform distribution of sawdust particles within the cement matrix, with improved interfacial bonding observed at the optimal 60% sawdust content, contributing to the enhanced mechanical properties of the composite. In conclusion, 60 vol.% sawdust reinforcement is optimal for enhancing the mechanical performance of Portland cement composites, offering a balance between strength and sustainability, suggesting its potential as a cost-effective, eco-friendly reinforcement for cement-based materials in sustainable construction practices. | |
