Concrete is widely used in domestic, commercial, recreational, rural and educational construction. Concrete basics aim to provide a clear, concise explanation of all aspects of making quality concrete from the materials and properties involved through planning, preparation, casting and curing. Concrete is mixture of cement, coarse, fine aggregates and water. The aim of this research is to determine the influence of spent catalyst and seashells in concrete replacing cement and coarse aggregate. The objective of this study is to analyze the behavior of concrete using seashells and spent catalyst and to compare between the normal concrete and concrete mixed with seashells and spent catalyst. Cement was partially replaced in (10%, 15% and 20%) with spent catalyst and Coarse Aggregate was partially replaced in (5%, 10%, and 15%) with seashells. Cubes were cast in mould with dimension (150mm x 150mm x 150mm) using mix design calculation for C30 grade which was done according to ACI method. The result show that the compressive strength is increased up to 15 percent replacement of cement and coarse aggregate with spent catalyst and seashells for 28 days. The addition of spent catalyst and seashells has positive effect on the compressive strength of cube.
