| 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. |
