Aggregates that have been recycled are those that have been gathered from demolition and building debris. The manufacturing of demolition trash has increased recently, which has contaminated the ecosystem. Thus, substituting recycled materials for natural aggregates will reduce trash generation. The application of recycled aggregates is expanding daily, which will substantially lower the cost. This paper's major goal is to determine the strength characteristics of recycled aggregates so that they may be utilised as a substitute for natural aggregates. Flyash and alccofine are used to replace some of the binding material in an M40 grade concrete. Here, recycled aggregates are used to make concrete in place of natural aggregates to varying degrees (25%, 50%, 75% and 100%), partial replacement of cement with a flyash (25%) and alccofine (0%, 5%, 10% and 15%). Mix design of binary blended recycled aggregate concrete are done by using IS:10262-2019. Workability is measured and mechanical properties like compressive strength, flexure and split tensile strength were determined for 7days and 28 days. Alkaline attack should be calculated after 28 days of NaOH solution curing. The strength of the concrete is decreased suddenly if the recycled aggregates are increased more than 50%. More than 10% of alccofine content the strength is decreased
