Plastic garbage is one of several factors wrecking the planet's environment. Factors like the trouble involved in recycling plastic and its limited use contribute to the ensuing complications. The worldwide environmental effects of plastic trash are substantial. The goal of this study is to examine the impact of replacing some of the fine aggregate in concrete with poly-ethylene terephthalate (PET). The effects of this additive on concrete's mechanical and physical properties were studied. Six different concrete mixtures, with 0%, 10%, 20%, and 30% poly-ethylene terephthalate (PET) substitution for fine aggregate, were produced. The objective of the test was to compare the compressive strength of fresh and cured concrete using a Slump Cone. The results of the tests showed that the unit weight decreased, the mechanical properties of the concrete were damaged at varying rates, and that plastic waste could be disposed of in predetermined ratios, suggesting that it might be utilised effectively in industrial contexts.
