Sea sand is a more easily accessible sort of sand than river sand. Sea sand is not frequently used since it could contain hazardous materials. Sea sand might be used to either address the existing problems with concrete's strength and durability or provide an excellent substitute for river sand, which is seriously endangered due to excessive use of excavation techniques in almost every country on the planet. This investigation was limited to fine aggregate only. Sand is used as a fine aggregate in concrete and is a crucial part of engineering projects. One such easily obtained substitute that is already in use in coastal areas is sea sand. There are several places where sea sand is gathered, such as Parangipettai, Killai, Kollidam, and Kodiyambalaiyam. In this study, sea sand is used as a fine aggregate to investigate its chemical properties. Physical characteristics such as specific gravity and sieve analysis were determined in this investigation. The EDS of river and sea sand was also examined. The percentage of sand retained on each screen is typically displayed in a sieve analysis, which is the output of the sieve analysis of sand. With the use of this information, the particle size distribution of the sand may be ascertained and it can be categorised using accepted grading guidelines. Because of its chemical makeup, sea sand is mainly employed as a fine aggregate in concrete
