The demand of concrete in construction is increasing day by day. The materials used for the concrete are cement, coarse aggregate, fine aggregate, water, admixtures (if any). The use of cement causes the CO₂ emission in the environment. So to reduce the emission of CO₂, the cement should be replaced or substituted by other materials. In construction the use of bricks are necessary, the brick dust waste which is obtained by the transportation or in the making of the bricks has pozzolanic properties that enable it to play an important role in the strength and durability of concrete. The use of Coarse aggregate in concrete reduces the natural stone deposits. To overcome this problem, coconut shell is used as a partial replacement of the coarse aggregate. For the replacement of this material, different tests on the material were performed and mix design is prepared. Further, brick dust and coconut shells were partially replaced with cement and coarse aggregate respectively in different proportion and the compressive strength test on the concrete was performed. After the test, it is concluded that the concrete with Brick dust replacement of 10% and coconut shell replacement with 20% gave the strength which was nearly same as nominal concrete
