Abstract
Raffia Hookeri known as “doka” in Akan is abundant in Ghana and its main use is for extraction of local wine.
It yields many fibres including piassava fibre which was used as broom and has been abandoned in the advent of
plastic brooms. Piassava fibre was used for experimental study as fibre reinforcement in concrete, and reported
on workability, density, compressive strength, tensile strength and toughness of the concrete. The study used a
basic concrete mix of 1:1.5:3, and 10 separate batches with percentage weight fraction of fibres; 0.00%, 0.25%,
0.50% and 0.75% and three different water/cement ratios of; 0.45, 0.50, and 0.55 at constant aspect ratio of
100mm for both cubes and cylinders. In all, 0.50% Piassava fibre content and 0.50 water cement ratio enhanced
the tensile strength and toughness modulus of concrete while best compressive strength of 39.68MPa occurred
at 0.25% fibre content with 0.45 water cement ratio
