The use of Recycle product is increasing with innovation in present scenario. The utilization of waste product in the manufacturing of new product is a challenging job. The Natural Resource decreases in a short period and therefore the use of waste product is necessary. In the construction field of the world, use of Demolished Concrete Waste as alternative of coarse aggregate plays a vital role to save natural resources and economically good for us. Natural sand is a prime material used for the preparation of concrete and also plays an important role in Mix Design. One such material is Quarry stone dust: a by-product obtained during quarrying process. Attempts have been made to study the suitability of Quarry Dust as sand replacing material and it has been found that Quarry Dust improves the mechanical properties of concrete as well as elastic modulus. This present work is an attempt to use Quarry Dust as partial replacement for fine aggregate in concrete and Demolished Concrete Waste as partial replacement for coarse aggregate in concrete. The main object of this project is to determine the Compressive strength, Split tensile strength, Flexural strength. Various mixes were prepared for carrying out the research by varying the proportions of cement, sand and aggregates. All mixes were designed for characteristic strength (fck) of M20. The Compressive strength, Split tensile strength, Flexural strength of concrete was tested in laboratory after 7, 14 and 28 days.
