A Study on Strength Properties of Mortar According to Mass ratio change using Oyster shell as Aggregate

굴 패각을 잔골재로 사용한 모르타르의 질량비 변화에 따른 강도특성에 관한 연구

Oyster shell is produced 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 sand. So we produced mortar test using different law of multiple proportions of grounded oyster shell powder of its particle size according to fine aggregate standard and reviewed strength Properties.
