The demand of construction material is increasing every day. Concrete is widely used in construction. In this research waste Brick & Marble is used as coarse aggregate produced from demolition of building which is waste material. We can use this waste material as coarse aggregate. Waste Brick and marble are vary economic as compared to natural aggregate & reduce the waste generated by demolition of building. This study aimed to investigate the suitability of using brick ballast and marble waste in concrete. Three replacement levels 10%, 20% and 30%, were compared with the conventional concrete. The tests on concrete showed that the mechanical properties (compressive and splitting tensile strengths) of concrete containing waste brick ballast and marble ballast were well comparable to those of the concrete without brick ballast. The production of normal aggregates and building stones through quarrying is an expensive process. Quarrying involves deep excavation and blasting of rocks. This has created an unpleasant environment by leaving scars on land. Brick ballast and marble waste products chips when crushed to the required nominal sizes such as 10mm, 14mm, 20mm, etc. provide a rough and irregular surface which aids in bonding of cement paste and the aggregate. Therefore the bond strength of concrete is likely to be increased when these aggregates are used. Careful consideration of the water absorption of brick ballast aggregates will be taken in the mix design to ensure that the workability of the mix is achieved.
