| Abstract | This study is aimed at investigating the physical and mechanical properties of water hyacinth fiber and the mechanical properties of fiber reinforced roofing sheet using water hyacinth as fiber and rice husk ash as additive. High-range water reducing agent was used as admixture in the mortar with rice husk ash in order to reduce water content and to maintain the same workability as the mortar without rice husk ash. The fiber content was the main parameter and varied in order to obtain the optimum proportion. The production method adopted in this study was developed by Intermediate Technology Development Group and testing procedures were performed in accordance with the relevant ASTM standards. Test results showed that a mix having 2% fiber content by weight of cementitious material with rice husk ash was the optimum mix of the composite. The ductility of water hyacinth fiber r einforced semi- sheet roofings was significantly high compared to that of plain mortar semi-sheet roofings. Test r esults indicated that water hyacinth fiber is a highly absorptive fiber and its tensile strength and modulus of elasticity are low. The production method adopted was found to be simple, systematic and suitable for rural development. The size of semi- sheet roofing used in this study was a little larger and heavier for Asian people. |
