Structural Behaviour of Fibre Reinforced Concrete Using PET Bottles

Abstract

This research work reports the experimental study of Fibre Reinforced Concrete (FRC) using recycled PET bottle as the fibre. The PET fibre was added at 0.5%, 1.0%, 1.5%, 2.0%, 2.5% and 3.0% volume of the total aggregates. The workability tests and compressive strength tests were carried out and results of workability show that the volume fraction of fibre between 0.5% and 1.5% are workable with 0.6 water-cement ratio while that between 2.0 and 3.0 were not workable. Also too, the compressive strength for the volume fraction of fibre of 0.5% and 1.0% improve more than the control while those above 1.0% have a reduced strength compared with the control. It is recommended that PET bottle fibre up to 1.0% can be used for structural works particularly ground floors
