The concrete is the most popular building material in the world. It is composed of cement, fine aggregate[sand], and coarse aggregate mixed with water. Sand is the one of the material in concrete, it mostly used in all construction purposes. In current situation river sand has been most popular choice for the fine aggregate component of concrete, but overuse of the material has lead to depleting of securable river sand deposits and inconvenient transportation rises the cost of river sand resources. Therefore, it is desirable to obtain cheap, ecofriendly substitutes for river sand that is partial preferably sea sand. This project deals with the usage of sea sand in the construction field with the removal of salt content and organic matter from the sand. An experimental setup for boiling and number of washes with ample water are made suitable for reducing the salt content. And for removal of micro organic matter, wash the sea sand with water along chemical solution. To equalize its properties similar to the river sand. This study gives a comparison on the M25 grade conventional concrete properties and the partially replacement of sea sand as fine aggregate in concrete was used in gradually increasing proportion to make concrete blocks and test the compression and tensile tests at 7, 14, 28 days of curing. The test results for both the sets of concrete were tabulated and plot the graphs. Compare the test results evaluate the which percentage gives the best result.
