Abstract: Concrete is normally developed using river sand as fine aggregate. In this work, M30 grade of concrete has been developed by the mix proportion of 1:1.22:2.54 with water cement ratio 0.42. In this proportion, 1.22 parts of fine aggregate is partially replaced with sea sand. Concrete specimens were mould with 10%, 20%, 30% and 40% of sea sand replacing the fine aggregate. Various tests such as axial compressive strength, split tensile and flexural strength have been conducted on the hardened concrete after 7, 14 and 28 days curing and the results are tabulated. From the test results, compressive strength, split tensile and flexural strength are satisfactory up to 30% replacement of sea sand. With 30% replacement of sea sand, micro silica has been added as an admixture to increase the strength further.
