A Strength Properties According to Water cement ratio using Oyster shell as Aggregate
굴 패각을 잔골재로 사용한 모르타르의 물시멘트비에 따른 강도특성
Abstract
Oyster shell is light weighted and its strength characteristic is similar to sand. So we produced mortar test piece using grounded oyster shell powder under 0.5mm, which is a standard of fine aggregate, and reviewed strength properties according to water cement ratio. In our test, we used two kinds of oyster shell particles: below 0.6mm and 1.2~2.5mm. Water cement ratio is varied 40% to 100% and we found that flexural strength and compressive strength are decreased in higher water cement ratio.
