| 1 | Effect of Pullout on Mechanical Behavior of Natural Fiber-reinforced Earth-based Composites |
This study presents an experimental investigation on pullout tests of natural fiber (straw) from earth-based matrices. A specially designed single fiber pullout apparatus was used to provide a quantitative determination of interfacial properties that are relevant to toughening brittle materials through fiber reinforcement. The parameters investigated include a specially designed high strength earth-based matrix comprising of 60% laterite, 20% clay and 20% cement. The medium from which the fiber was pulled included a control mortar mix without fibers and a mortar mixed with 5, 10, 15 and 20 percent fibers by volume. The results indicate that increasing the fiber embedment length and the fiber volume fraction in the cement mortar increase the peak pullout load and the pullout work. The implications of the results are then discussed for potential applications in the design of robust earth-based building materials for sustainable eco-friendly home. | K. Mustapha, E. Annan, S. T.
