Concrete is a dependable and long-lasting material for the building sector, because of its versatility, strength, and durability qualities. However, the quick depletion of those resources and the consequent rise in price are becoming attention-seeking issues in the field of construction. Many organic rude aggregates are second-hand as the result of facts on an all-encompassing scale, and abundant rising countries with their own government have had supply issues. Researchers and businesses are focusing on recycling waste concrete to create new building materials in order to meet the growing demand for infrastructure development today. Recycled crushed stone has been practically useful within the construction sector, and the use of recovered construction aggregates is effective at keeping the environment clean. The aim of this study is to develop sustainable and cost-effective concrete with recycled aggregates as coarse aggregate and their by managing construction waste. In this study, aggregates as coarse materials are restored by recycled stones from broken concrete in the range of 0%, 25%, 50%,75%, 100%, and 100% saturated surface dry aggregate concrete with a grade of 25 N/mm2. The finished concrete mix is tested and compared with normal concrete as a control mix according to workability studies and mechanical properties. The test is done after 7, 14, and 28 ages of curing to measure the strength characteristics. This paper offers a technique for assessing the long-term efficiency of concrete produced using reused aggregate.
