It can be lead to a search for alternative material for replacement of cement. The Ordinary Portland cement emits large amount of co₂. Waste material production is increasing day by day. The cost of cement is increasing day by day. Thus need to find alternative binding materials that can be used as partial replacement of cement. Agricultural waste material, in the case, coconut shell, is an environmental pollutant, it should be collected. Using coconut shell (CS) as partial replacement should be urged as a priority in construction cost lowering measure. Aggregates sources are depleting very fast leading to significant increase in cost of construction. The coconut shell ash is used for the partial replacement of cement. The laboratory tests result carried out using coconut shell ash (CSA) as a partial replacement for cement used in concrete. In this particular study, M30 grade of concrete was prepared by replacing coconut shell for coarse aggregate and also replacing cement with coconut shell ash. Cement is replaced by 10%, 15%, and 20% of coconut shell ash in cement. Coarse aggregate is replaced by 10%, 15%, and 20% of coconut shell in conventional aggregate. Test were carried out to find the compressive strength, Split tensile strength and corrosion resistance test using cube and cylinder specimens respectively. The results show that usage of coconut shell and coconut shell ash as partial replacement in light weight concrete. Key Words: Coconut Shell Ash, Coconut Shell, Compressive Strength, Replacement, Aggregate, Corrosion resistance, Split tensile strength. 1. INTRODUCTION Infrastructure development across created the world demands for building construction materials. Concrete is used to construct the various types of concrete structures. Cement is leading material in concrete structure. Cement sources are depleting very fast leading to increase in cost of construction. Aggregate sources are depleting very fast to significant increase cost. Agricultural wastes increasing day by day. Its disposal has real problem. The coconut shell becomes eco-friendly material. Coconut shell being hard and not easily degrades material. Coconut shell burned in high temperature it can be produce coconut shell ash and it should be used for partial replacement of cement. Crushed coconut shell (20mm) size can be used for partial replacement of coarse aggregate. Reduction in the construction cost and light weight concrete produced. This aim is to determining the strength of the concrete by using partial replacement of cement with coconut shell ash (CSA) and coarse aggregate with coconut shell (CS) in concrete. 2. REVIEW OF THE LITERATURE 1. Pravin V. Khandve, Shrikant M.Harle In this literature partial replacement of coarse aggregate with coconut shell in the concrete. It can be help to reduce the waste and pollution. The construction industries have replaced conventional aggregate to light weight aggregate. It can be used to reduce the size of the members in the structures. In this experimental setup percentage of increase coconut shell the strength increase in 7days also the strength increased in 28 days curing strength. Replacement of coconut shell as coarse aggregate increases as the workability Of concrete increases. Replacement of coarse aggregate with coconut shell increases will reduce the specific gravity of concrete. Density of concrete should not be less than 2000 Kg/cum. 2. Kulkarni Parag Pramod, Prashant Ganpat Chavan, Pagar Chetan Bhaskar Crushed coconut shells are replaced in concrete. Coconut shells are easily available at low cost price in our country. In this experimental study light weight concrete can be prepared by using aggregate with coconut shells. Water absorption and moisture content of the crushed coconut shell is found to be 24% and 4.24% respectively. Normally coconut shell aggregates having high water absorption capacity because of higher porosity in structure. The specific gravity of crushed coconut shell is 1.05. 3. Shaik.Aliimran Tippu and Vr.Prasanth Kumar In this literature have conducted compressive strength and split tensile strength characteristics with complete replacement of coarse aggregate with coconut shell to produce light weight concrete. To replace cement by exploitation silica fume admixtures with completely replacing percentages 0%, 10%, 15%, 20%, 25%, and 30%. The mix proportion
