본 발명은 기존 시멘트를 이용한 경화 방법에서 시멘트를 제외하고, 소량의 반응형 접착제를 첨가해 폐패각(꼬막껍데기, 굴껍데기 등), 골재, 마사토, 흙 고화제 및 알긴산나트륨 등을 이용한 어초 등의 제조에 사용되는 건축 또는 토목 자재용 조성물 및 이를 이용한 건축 또는 토목 구조물 제조 공법에 관한 것이다. The present invention is a method of hardening using conventional cement, except for cement, by adding a small amount of reactive adhesive to produce waste shells (cocktail shells, oyster shells, etc.), aggregate, massato, soil hardener, and fish reefs using sodium alginate, etc. It relates to a composition for construction or civil engineering materials used for manufacturing and a construction or civil structure manufacturing method using the same.

수산물은 생산·가공·유통·판매의 과정에서 다른 농림축산물에 비하여 상대적으로 많은 양의 부산물이 발생하고 있음에도 불구하고 이러한 수산부산물은 재활용되거나 다시 자원화되지 못하고 대부분 폐기되고 있는 실정이며 폐기과정에서 폐수 및 악취를 발생시키며, 불법 매립, 해양 투기 및 방치 등으로 인하여 여러 가지 환경문제를 야기하고 있다.Although aquatic products generate a relatively large amount of by-products compared to other agricultural, forestry and livestock products in the process of production, processing, distribution, and sales, these by-products are not recycled or recycled and most of them are discarded. It generates odor and causes various environmental problems due to illegal reclamation, dumping in the sea, and neglect.

특히 우리나라 수산물 생산과 수출에서 큰 비중을 차지하고 있는 굴의 경우 개체에서 패각이 차지하는 비중이 약 70*?*인데도 불구하고, 이들 굴 패각은 가공 과정에서 대부분 폐기 또는 방치되며, 극히 일부분만 채묘용, 비료 및 사료용 등으로 재활용되고 있다. 전 세계적으로 2016년 기준 4,380억 톤의 굴 패각이 발생했으며 대부분 버려지고 있으며, 전체 굴 패각 중 37%는 고형폐기물회사에 수거되며, 25%는 해양투기, 16%는 다짐재, 12%는 매립처리되며, 나머지 10%는 다양한 형태로 거래되고 있는 것으로 조사되었다.In particular, in the case of oysters, which account for a large proportion of Korea's aquatic product production and exports, despite the fact that shells account for about 70*? It is recycled for fertilizer and feed. As of 2016, 438 billion tons of oyster shells were generated worldwide and most of them are thrown away. Of the total oyster shells, 37% are collected by solid waste companies, 25% are dumped at sea, 16% are compacted materials, and 12% are landfilled. It was investigated that the remaining 10% is being traded in various forms.

국내의 경우 수산물 생산과 소비 증대 중심의 정책이 추진되고, 굴 패각 등 수산부산물에 대한 폐기물 관련 환경규제가 강화되고는 있는 반면, 수산부산물의 재활용 및 자원화 정책은 상대적으로 미흡한 측면이 있다.In Korea, policies centered on increasing production and consumption of aquatic products are being promoted, and environmental regulations related to waste related to aquatic by-products such as oyster shells are being strengthened, while policies for recycling and recycling fishery by-products are relatively insufficient.

특히 최근 해양수산부는 전 세계적으로 증가하고 있는 양식수산물 수요에 효과적으로 대응하기 위하여 스마트 양식 산업 활성화 정책을 추진하고 이를 통하여 수산물 생산량을 확대한다는 목표를 세우고 추진 중이기 때문에 향후 수산물 생산량 증가에 따라 부산물의 발생량도 지속적으로 증가할 것으로 예상되고 있다.In particular, recently, the Ministry of Oceans and Fisheries is promoting a policy to revitalize the smart aquaculture industry in order to effectively respond to the increasing global demand for aquaculture and aquaculture, and through this, set and is pursuing the goal of increasing aquaculture production. is expected to increase to

굴 패각의 무단방치로 인해 지역의 미관이 훼손되고 도시지역 이미지가 저해되고 어민들의 어업도 막대한 피해를 입고 있으며, 지역관광 산업에도 악영향을 미치고 있다.Unauthorized neglect of oyster shells damages the aesthetics of the region, tarnishes the image of urban areas, and damages the fishing industry of fishermen, and adversely affects the local tourism industry.

또한 환경적으로 패각 처리의 복잡한 절차로 인해 불법 투기 및 매리, 야적되는 굴 패각이 증가하고 있으며 이로 인한 악취로 인한 지역주민들의 민원이 끊기지 않고 있으며, 또한 방치된 패각에서 석회물질이 빗물에 씻겨 바닷물로 유입되어 수질오염이 우려되는 사항이다.In addition, due to the complicated procedure of shell treatment in an environment, illegal dumping, dumping, and stocking of oyster shells are increasing, and complaints from local residents due to the bad odor are not stopped. It is a matter of concern for water pollution due to inflow into

이에 따라, 현행 폐기물 관리법령에서는 폐 패각을 건축재료 원재료, 비료, 사료, 공유수면 매립지역의 성토재 등으로의 재활용을 허용 있으나, 실제 성토재로 활용 시 일반 토사류 등을 70%이상 혼합하여야 하는 문제점이 있으며, 비료 및 사료로 이용하고 있으나 그 사용량이 미미하고 건축, 토목자재로 활용은 전무한 실정이다.Accordingly, the current waste management laws allow recycling of waste shells as raw materials for building materials, fertilizers, feed, and embankment materials in reclaimed areas of public waters. It is used as fertilizer and feed, but the amount used is insignificant and there is no use for construction and civil engineering materials.

굴 껍데기(굴패각)는 탄산칼슘 94%, 석고 등 기타 성분이 6%로 구성되어 있어 이를 효율적으로 활용하면 골칫거리인 굴 껍데기(굴패각)를 유용한 자원으로 재활용할 수 있다. 폐패각(굴껍데기)을 이용한 특허는 다음과 같다.Oyster shells (oyster shells) are composed of 94% calcium carbonate and 6% other ingredients such as gypsum. Patents using waste shells (oyster shells) are as follows.

특허등록 제10-1678030호는 폐패각을 이용한 미끄럼 방지용 충진재 제조방법으로 폐패각을 세척, 건조, 분쇄, 이물질을 선별하여 분리하는 제조방법에 관하여 기술하고 있다.Patent Registration No. 10-1678030 describes a manufacturing method of washing, drying, pulverizing, and sorting and separating waste shells as a method for manufacturing a non-skid filler using waste shells.

특허등록 제10-2120858호는 전복폐패각을 포함하는 조림용 고형비료 및 그 제조방법으로 전복폐패각 분말, 쌀 왕겨, 황토, 구아노, 정장석 분말 및 어류 부산물 중에서 선택된 1종 이상을 포함하는 조림용 고형비료를 제조방법에 관하여 기술하고 있다.Patent Registration No. 10-2120858 is a solid fertilizer for afforestation containing abalone shells and a manufacturing method thereof.
