In our country where over 80% of land is mountainous, decomposed granite soils are often used as building materials for civil engineering works. Seashores are having great difficulties in management and treatment of marine byproducts that are left vulnerable. It is necessary to find a way to efficiently utilize such vulnerable marine byproducts. For this reason, shell and ocher were mixed together in order to efficiently utilize ocher that is being used frequently as a building material in civil works and shell that is a type of marine byproducts being thrown away. The purpose of this study is to examine the extent to which shell-ocher mixture can reduce liquefaction through cyclic triaxial test. The author of this study aims to provide the possibility for application at construction site of shell-ocher mixture.
