Concrete is the widely used material in the world. This automatically creates a huge demand for ingredient of concrete (Fine Aggregate, Coarse Aggregate and cement). From the environment point of view, the huge extraction of the aggregate creates depletion and manufacturing of cement causes pollution. This scenario affects the world’s ecological balance. As a civil engineer, we have planned to replace the river sand which is widely used in construction by sea shell. Sea shell is the dead remain of the marine organism. We have replaced the sea shell after grinding it to the maximum size of 4.75 mm. The IS 10262-2009 was followed for the mix design of M20 grade concrete after that optimization of cement is done. Sea shell which is used in concrete confirming to the zone II as per IS 383-1970. Then cubes were casted for the 5 parts of partial replacement as 20%, 40%, 60 %, 80%, and 100 %. All the specimens are used for 7 & 28 days and tested for compressive, flexural and split tensile strength .We have observed the maximum strength is obtained for 80% replacement of sea shell.
