Abstract

This paper presents the results of combined experimental and theoretical studies of the statistical distributions of the strength and fracture toughness of recycled polyethylene-reinforced laterite composites for potential applications in building materials. The composites are produced with different volume percentages (0-30% v/v) and particle sizes (~300±0.02, ~600 ± 0.03, ~900 ± 0.03, ~1,200±0.02, ~1,500±0.04, and 1,800±0.03 μm) of powdered polyethylene (PE) in a laterite matrix. The composites with ~900±0.03 μm and 20-volume percentage of PE are shown to have the best combination of flexural-compressive strengths and fracture toughness. The statistical variations in the flexural-compressive strengths and fracture toughness are well characterized by the Weibull distributions.
