Concrete is one of the most widely used construction material in the world, Increase in population growth may increase in various demands like construction works like residential buildings, bridges, dams and roads etc, so the problem of waste disposal has become a major problem in the developed countries as well as developing countries like India, Recent technology has greatly improved the recycling process for waste concrete and the present study about comparison of properties of natural and

Six mixes of concrete with 0%, 10%, 20%, 30%, 40%, 50% replacement of natural aggregate with recycled aggregate were cast respectively in addition to this partial replacement to the weight of cement is done with Metakaolin (0%, 5%, 10%, 15%, 20%, 25%), flyash (0%, 5%, 10%, 15%, 20%, 25%) and weight of fine aggregate with M-sand (0%, 10%, 20%, 30%, 40%, 50) for all mixes. The compressive strength, flexural strength, split tensile strength were determined at the age of 28 days and the study focuses on the possibility of the use of recycled aggregate as a structural material as showed a gradual decrease in compressive strength, split tensile strength, flexural strength as the percentage of recycled aggregate is increases gradually.
