Fiber cement products mixed with coconut fiber yielded lower density than
that of oil palm fiber. The mixtures of fiber cement products containing up to 15% of both natural fibers
by weight of binder yielded the acceptable physical and mechanical properties. Furthermore, the thermal
conductivity of the natural fiber cement sheets was 60% less than that of the control specimen. The
results of this research can be used as a guideline for using agricultural residues to develop fiber cement
products for residential building applications.
