In this process the soaked sea sand which is dried in an oven is taken, after this process sea sand is taken in a vessel with some water and is heated up to when it reaches a temperature of 100 °C [10] Fig. 2. After this entire process, the sea sand is again dried in an oven and the remaining water is tested for chloride test.The lack of river sand has led to the use of sea-sand and crushed stone fines in many countries, with the use of sea-sand in the UK being an example [4].More than 90% of the world’s dredged sea-sand has been used as a raw material in the construction industry, with over 45% of the dredged sea-sand being used as fine aggregate for Use of sea-sand and seawater in concrete construction:
