Abstract Sand and gravel are mined world-wide and account for the largest volume of solid material extracted globally. Formed by erosive processes over thousands of years, they are now being extracted at a rate far greater than their renewal. Furthermore, the volume being extracted is having a major impact on rivers and deltas, results in loss of land through river, lowering of the water table and decreases in the amount of sediment supply. This emerging problem obliges contemporary material usage to balance the ecology. In this essence the abundant availability of sea sand can be utilized as an effective replacement for natural aggregate which will be beneficial for both circumstances. Hence this research project investigates the use of sea sand in concrete construction. This study proposed with hot water washed sea sand with various replacement in concrete from 10% to 100% with the increment of 10% resulted in higher mechanical properties in all the replacement.
