Application of PET in Construction as a Fine Aggregate Replacement in Concrete Mixes Khaled Al-Shehri

Plastic bottle waste is a huge environmental problem, particularly in Saudi Arabia. Hence, there is no official recycling problem. Thus, The need for a practical solution has risen. Plastic waste is a serious environmental problem present in all modern countries. It poses many threats such groundwater contamination, global warming, and toxic bio-accumulation. This study concluded that 827,114 tons of plastic is produced each year in Saudi Arabia. Moreover, only 15% is recycled. This project aims to propose a feasible solution for the un-recycled plastic content by reusing as a fine aggregate replacement in concrete mixes. Upon reviewing the literature, it can be inferred that Replacing PET with certain ratios can help reduced the amount of unrecycled plastic while maintaining the optimal structural properties of concrete. Our project is divided into three parts: Environmental impact of PET plasticApplication of PET in sustainable constructionGeneral and specific statistical compressive strength (f'c) models of PET-added concret
