Oyster shells produce 280,000 tons of waste each year, but their processing limitations have adversely affected the environment, aquaculture and tourism. In additioncalcium carbonate, which is a natural aggregate necessary for the manufacture of various block products for construction and engineering, is a necessary ingredient for the manufacture of various block products. Calcium carbonate, which is a component of oyster patch, is used in food, medicine and cosmetics, has a wide range of recycling options. Therefore, by recycling oyster shells, cost reduction and environmental problems can be solved.1) However, it is necessary to maintain a stable physical property of compressive strength and absorption rate to recycle oyster chips into cosmetic functional or block materials.2) In this study, to improve the compressive strength and water absorption of the physical properties of oyster shells, block was prepared by adding polymer hardener. The size of the oyster shell was divided into three sizes to investigate the effect of size distribution of oyster shell on water uptake and compressive strength. In addition, cement produced 25 % of the oyster shell mass, 10 % of the polymer hardener, 10 % of the cement mass, and 20 % of the water and polymer hardener, based on 100 g of oyster shell. The EVA-Acryl-Latex composite polymer curing agent developed in this study confirmed the possibilities of complementing the water absorption and compressive strength in product of recycled oyster shells. In addition, it was confirmed that the degree of absorption, compressive strength and flexural strength were influenced by the size of the oyster shell and the kind of the polymer hardener. As a result, the EVA-Acryl-Latex composite polymer developed in this study can maintain the compressive strength and absorption rate, which are physical properties, in order to recycle the oyster shell to the block, thereby increasing the recycling rate of the oyster shell and further reducing the cost and environmental problems.
