Abstract
This study deals with the effects of using Polyethylene Terephthalate (PET) and river sand in roof tile production. This work is based on experimental study of roof tiles produced with river sand and recycled PET in varying proportion of 10%, 20%, 30%, 40%, 50%, 60% and 100% of PET combined with the corresponding fine aggregate percentage. The PET plastics used were derived from waste plastic bottles for soft drinks. The shredded plastic was subjected to heat and ensured that it does not lose it’s plasticity. The tests which were performed to evaluate the physical and mechanical performance of this material were sieve analysis, specific gravity, water absorption, density and compressive strength. The results show that recycled PET replacement gives better results for 40 and 50% of plastic composite tile than Ordinary Portland Cement (OPC) at 28 days. In conclusion, the plastic composite tiles have both good strength and absorptive property for roof tiling.

Summary
Building materials have experienced a considerable measure of change from old circumstances till this present innovation time [1]. A building as a structure consists of several interconnected elements coming together to satisfy needs [3]. These needs usually vary in accordance with design and specifications as presented by relevant parties in the construction industry. There is high value and importance placed on the roofing of any structures. Agbede et al [8] showed that roof tiles (concrete roof tiles) can be produced using Rice Husk Ash (Rha) in partial replacement of cement. Kolawole et al [9] carried out research on developing coco-nut fibre cement composite roof tiles and concluded that with optimum 10% coco-nut fibre an economical composite roof tile was achieved.
