In this project Sea sand was collected from kalpakkam beach and it was added to the concrete as a partial replacement of Fine Aggregate in the proportion 0%, 20%, 40%, 60% to find out the behaviour of sea sand in concrete under compressive strength test and split tensile test after 28 days of curing. Mix design (M40) was done as per IS 10262:2009 and then the proportion of concrete from the mix design was arrived and in this project coarse aggregate proportion of mix design consist of 75% of 20mm Coarse aggregate and 25% of 12mm Coarse aggregate. Steel fibres (1% by total volume of concrete) were added to the concrete cubes and concrete cylinders (excluding control cube and control cylinders). The test result shows that, compressive strength and split tensile strength was decreased for the sea sand proportions 20%, 40% and 60% when compared with control cube and control cylinder. The control cube has highest compressive strength 51.37 N/mm2 when compared to sea sand proportions 20%, 40% and 60%. The sea sand proportion 20% has high compressive strength 47.55 N/mm2 when compared to sea sand proportion 40% and 60%. The sea sand proportion 40% has compressive strength 45.24 N/mm2 and sea sand proportion 60% has lowest compressive strength 40.80 N/mm2. The control cylinder has highest split tensile strength 3.87N/mm2 when compared to sea sand proportions 20%, 40% and 60%. The sea sand proportion 20% has split tensile strength 3.58N/mm2 when compared to sea sand proportion 40% and 60%. The sea sand proportion 40% has split tensile strength 3.53 N/mm2 and sea sand proportion 60% has lowest split tensile strength 3.38N/mm2.
