Concrete technology is now focused on acquiring supportable materials for concrete for countering dependency on natural resources. Some of the ingredients employed to make green-concrete usually comes from industrial byproducts. To lessen reliance on virgin resources, attempts have been made to integrate by-products and wastes into concrete. Seashell garbage, such as oyster scallop, and mussel shells are abundant in some areas and is typically abandoned or landfilled with little re-use value. This research highlights prior studies on the seashell trash as a replacement for traditional resources in concrete and correlated products. The features of various forms of shell trash are explored, as well as the implications of putting shells into concrete. Because of the high concentration of calcium oxide in the trash, the material properties indicate that it is inert. However, adequate handling, such as high temperature and crushing to produce fineness, is preferable. Both cement and aggregate can be replaced with seashell trash. The key concern is its durability, as well as its real contribution to cement. According to the analysis, only up to 20% of shell waste may be utilised for concrete building.
