Application of Polyethylene Terephthalate Concrete as Paver Block

Abstract

This research is carried out to investigate the performance of concrete containing Polyethylene Terephthalate (PET) bottle waste as fine aggregate. PET bottle waste was chosen because it is being thrown after single use and cause environmental problem. This PET concrete then will be applied as a paver block for pedestrian walk. To reduce waste PET, the PET bottles was recycled and used in concrete mixture as a fine aggregate. PET bottles was cleaned and grinded into small irregular shape. Then, it was incorporate with the concrete and the test was conducted to find out the suitable strength for PET concrete that will be applied as paver block. The study was conducted by using cube mould to investigate the strength of the concrete. A total of four batches of concrete were produced namely, standard concrete and concrete containing PET of 5%, 10% and 15%. In this research, the compressive strength of the concrete were measured following British Standard method. The results revealed that the presence of PET in concrete will decrease the concrete performance. Nevertheless, the content of PET was specified in a specific limit to avoid the effect of concrete strength.
