This paper presents an experimental investigation into the properties and performance of sustainable concreteInthisstudy the natural aggregate replaced by recycled aggregate in different percentages (0%,20%,40%,60%,80%,100%). Thepercentage of recycled aggregate mixed in the definite proportion it improves the property of fresh and hardenedconcretelikeslump test, compressive strength flexural strength & tensile strength test up to optimum percentage. The results demonstratethatsustainable concrete can achieve comparable, if not superior, performance to conventional concrete, while significantly reducing carbon footprint and resource consumption. This study underscores the potential of sustainable concrete to transform the construction industry towards more sustainable practices.
