ABSTRACT
The relative properties of concrete reinforced with treated and untreated fibres obtained from Palm Oil Empty Fruit Bunch (POEFB) in concrete are reported in this paper. The criteria for comparison are density and durability characteristics. The densities were determined with the aid of 150 x 150 x 150 mm concrete cube specimens. The durability characteristics were assessed through sorptivity, coefficient of water absorption and water absorption tests. For these durability tests, 100 x 100 x 100 mm cube specimens were used. The analysis of the results showed that: (i) the densities of specimens containing POEFB fibres were higher than specimens containing the untreated fibres by as much as and 30% at both 28 and 90 days curing. and (ii) the inclusion of treated POEFB fibres improved the durability characteristics of the specimens determined through absorption, coefficient of water absorption and sorptivity tests. Absorption values for treated fibres were less than 10% at both 28 and 90 days of curing. Considering all the results as a whole, inclusion of treated POEFB fibres resulted in concrete with superior durability characteristics than specimens with untreated POEFB fibres.
