The use of natural fibres has proven successful in improving the mechanical properties of earthen construction. It is a low-cost and environmentally friendly alternative to using chemical stabilisers, such as Portland Cement. This paper presents an experimental investigation into the influence of jute fibre reinforcement on the compressive and tensile splitting strength of Jute Reinforced Compressed Earth Composites (JRCECs). The investigation considered three fibre lengths (10 mm, 20 mm and 30 mm) and three fibre dosages (0.125%, 0.25% and 0.50%) by weight. When compared to an unreinforced control mix, it was found that the incorporation of jute fibre increased the mechanical properties of the JRCEC, with the optimum mix providing an increase in compressive and tensile splitting strength of 100% and 85% respectively. Within the investigation, Computed Tomography (CT) scans were performed on the JRCEC samples to evaluate the influence of mixing methodology on the fibre distribution and orientation. Findings from this study showed that jute fibre reinforcement may be used to increase the mechanical properties of compressed earth composites, and highlights the importance of mixing methodology during the manufacturing process.
