Indian concrete journalSummary: The influence of ingredients in concrete plays an important role in the serviceability and durability. The region where sea and river meets is termed as Estuary. The water available in estuary is saline due to intrusion of sea water. The density of sea water is more than the fresh water and settles down, forms a layer around the sand particles. This sand has high influence on durability of reinforced cement concrete. Netravati estuary was selected for the present study to know the effect on concrete. Ten samples were collected along the estuary in one kilometer interval from the mouth of sea. The locations were identified as N1, N2, N3, N4, N5, N6, N7, N8, N9 and N10. The specimens were fabricated as per IS 456. The Half-potential test results show increase in length of estuary from mouth, there is decrease in corrosion rate. This study concludes that sand from estuary used in concrete highly influence on corrosion rate.
