ABSTRACT
This study is aimed at establishing the use of Plastic Fibres for the production of Interlocking blocks. The density, water absorption properties and flexural strength of the Fibre based concrete batches were determined and compared to that of a control batch. The batches were prepared with a fibre to aggregate ratio of 0.25%, 0.5%, 0.75% and 1.0%, and the mix design was done based on relevant concrete mix design codes. The 200mm x 100mm x 60mm block specimens were used for the flexural strength testing and the specimens were cured in water and tested after 7, 14, and 28 days, and the water absorption reduces with addition of fibre. The 0.25 fibre batch absorbed the most water, while 0.83% and 0.5% fibre had the highest density, while 0.25% fibre batch had the lowest density. Test on flexural strength showed that the addition of fibre enhances the strength of concrete. The 0.75% fibre batch produced the highest flexural strength after 28days.
