Abstract: The issues of sustainability are of prime concern these days as we use a large number of natural resources for producing materials such as construction materials. The recent trend in the construction industry is to use the alternative source of construction materials which can substitute the use of natural materials to reduce environmental impact in terms of energy consumption, pollution, waste disposal, and global warming. Aiming at characterizing the behavior of concrete structures made with eggshell powder and coconut shells are replaced in the proportions of the concrete mixture. In the present work, the experimental program was designed to study the properties like strength and workability of concrete by casting the cube of size 150 mm x 150mm x 150 mm and cylinder of size 30 cm height and 15 cm diameter by using M20 grade. This experimental study consists of testing compressive strength of three cubes and split tensile strength of three cylinders of conventional concrete and the comparative cubes and cylinders are made by using different proportions of coconut shells (i.e., 2%, 4%, and 6%) replacement in coarse aggregate and replacement of eggshell powder (i.e., 5%, 10%, and 15%) in place of cement at optimum strength obtained by proportions of coconut shells replaced in coarse aggregate.
