Replacement of river sand with sea sand and granite granules

Nowadays there is a demand for river sand for construction. To avoid these conflicts, we are up to a solution of using sea sand along with granite granules as fine aggregate in concrete. Granite granules are the waste product obtained while cutting granite which is cost effective and sea sand is abundantly available in coastal areas when compared to river sand. This full replacement can be used in Plain Cement Concrete (PCC). Concrete cube is cast to test the compression strength for M5 grade concrete (since it is for PPC). As a result, strength is obtained related to cube cast using river sand in concrete. Using this result, we have figured out that granite granules can also be a better replacement with sea sand. Further studies are going on to use it in Reinforced cement concrete (RCC) by refining chloride from sea sand or by adding admixtures with concrete to prevent corrosion of reinforcement.Nowadays there is a demand for river sand for construction.
