The Examination of Strength Properties of Mortar with Variation of Fine Particle Size Distribution of Oyster Shell

굴 패각의 잔골재 입도분포 변화에 따른 모르타르의 강도특성

In this study, mortar strength was measured by grinding oyster shell and changing the particle size distribution. For the experiment, the oyster shells were processed to a fine aggregate size of 10mm or less. In this experiment, seven particle size distribution conditions were selected and tested. Because oyster shells are different in density from sand, their volume ratios were calculated and converted to mass ratios of 1: 3. The strength test was carried out one day after the steam curing.
