Abstract

Oyster shell is produce by shucking process in oyster farming in southern coast of Korea. In average, about 6.7kg of oyster shell is produced as an industrial waste for 1kg of oyster flesh, and even only in last year, it is estimated that about 150,000 ton of oyster shell is produced. Oyster shell is light weighted and the strength characteristic of it is similar to send. So we produced mortar test piece using grounded oyster shell according to aggregate and reviewed strength characteristic. Therefore, in this study, the strength characteristics of the test specimen are evaluated by artificially altering fineness modulus and curing method by processing oyster shells.
