The last decade was dominated by a serious problem that now affects all the planet’s natural ecosystems: increasing growth of plastics and microplastics are difficult to dispose of. One strategy mitigate this is close life cycle one them—polyethylene terephthalate (PET)—by reusing it within most common building materials, such as mortars concretes. reuse PET waste aggregates also allows us limit CO2 emissions released during production aggregates. This paper analyzes outcomes many studies carried out on characteristics cementitious mixtures reinforced with material. Many researchers have demonstrated how used reinforcement concretes can produce an increase in mechanical strengths corresponding without PET. tensile strength resin higher than concrete; so, combining two materials possible obtain mixture overall strength, resulting increased flexural reduced cracking. Using effective size fibers, achieve ductility toughness mixture. Several reveal reduces density consequent decrease weight structural loads, while workability increases using spherical smoother
