Abstract

A porous artificial fish reef is provided to foster plankton in marine environment, to prevent the oxidation of the fish reef and to form better fishing ground by employing electro arc furnace oxidizing slag in the artificial fish reef. A porous artificial fish reef is prepared by a process comprising: mixing water of 100-150kg/m^3, cement of 290-380kg/m^3, aggregate having size of 13-2.5mm of 1590-1950kg/m^3, high strength admixture of 30-120kg/m^3, CSA expander of 3-4kg/m^3, pigment of 10-40kg/m^3 and at most 0.3% of retardant; molding the mixture in a mold; and curing the mixture. The aggregate is the electro arc furnace oxidizing slag which is generated from a steelmaking process using pig iron in electro arc furnace. The mold has a form of a cube. For the curing, the mixture is subjected to an open stowage for 28 days or subjected to a steam chamber.

최근에는 바다의 중요성이 인식되고 있고, 이러한 인식과 더불어 바다 목장화 사업을 추진하고 있는데, 이러한 바다 목장화 사업의 가장 중요한 사업으로 인공어초를 바다에 넣는 것이다.Recently, the importance of the sea has been recognized, and with this recognition, the sea ranching business is being promoted. The most important business of the sea ranching business is to put artificial reefs into the sea.

상기와 같이 인공어초를 바다에 넣어두면 물고기의 도피처와 산란 장소가 마련되고 플랑크톤이 많이 서식하게 되므로 새로운 어장이 형성되어 어획량이 늘어나는 등의 효과가 발생한다. If the artificial reefs are put in the sea as described above, the shelters and spawning places of the fish are prepared and the plankton is inhabited a lot, so that a new fishing ground is formed and the catches are increased.

따라서, 이러한 인공어초의 개발이 활발히 이루어지고 있으나, 바다 속에 들어가 있는 콘크리트제품(인공어초)이 새로운 환경오염을 일으키는 문제점이 있었고, 조직이 치밀해서 미세 플랑크톤이 잘 서식하지 못하는 등의 문제점이 있었다.Therefore, the development of such artificial reefs has been actively made, there was a problem that the concrete products (artificial reefs) in the sea causing a new environmental pollution, there is a problem such that the fine plankton does not live well due to the dense tissue.

상기한 문제점을 해결하기 위해서 종래에는 대한민국특허청 등록특허공보 제10-0195529호에 '인공어초'가 개시된 바 있다.In order to solve the above problems, the 'artificial fish' has been disclosed in the Republic of Korea Patent Publication No. 10-0195529.

본 발명에 의한 다공성 인공어초에 의하면 다음과 같은 효과가 발생한다.According to the porous artificial reef according to the present invention the following effects occur.

(1) 구멍이 많아서 플랑크톤이 많이 서식하는 환경이 된다.(1) Due to the large number of holes, it is an environment where plankton is inhabited.

(2) 해수에 쉽게 산화되지 않는다.(2) It is not easily oxidized in seawater.

(3) 해수가 인공어초의 내부로 유출입할 수 있어서 보다 좋은 어장을 형성할 수 있다. (3) The seawater can flow in and out of artificial reefs, making it possible to form better fisheries.

본 발명은 물 100~150kg/㎥, 시멘트 290~380kg/㎥, 13~2.5mm 크기의 골재 1590~1950kg/㎥, 고강도혼합제 30~120kg/㎥, CSA팽창제 3~4kg/㎥, 안료 10~40kg/㎥에 지연제를 시멘트 사용량의 0.3%이내로 혼합하는 혼합공정과; 상기 혼합공정 후에 몰드에 붓는 성형공정과; 상기 성형공정 후 양생하는 양생공정으로 이루어진다.The present invention is 100 ~ 150kg / ㎥ of water, cement 290 ~ 380kg / ㎥, 13 ~ 2.5mm aggregate 1590 ~ 1950kg / ㎥, high strength mixture 30 ~ 120kg / ㎥, CSA expanding agent 3 ~ 4kg / ㎥, pigment 10 ~ 40kg A mixing step of mixing the retardant within 0.3% of the amount of cement used in / m 3; A molding step of pouring into the mold after the mixing step; It consists of a curing process to cure after the molding process.

상기 혼합공정에서 사용되는 골재는 산업폐기물의 일종인 전기로 산화슬래그를 사용하는데, 전기로 산화슬래그는 선철을 주원료로 하고 전로에서 강을 제조할 때 발생하는 것으로 철분이 많이 함유되어 있어 밀도가 높은 것이 특징이다.The aggregate used in the mixing process uses an electric furnace oxidized slag, which is a kind of industrial waste. The electric furnace oxidized slag is produced when steel is made from pig iron as a main raw material and contains high iron density. Is characteristic.

상기 전기로 산화슬래그는 내마모성이 우수하고, 내산·내알카리성이 우수하며, 철분이 많이 함유되어 있어 인공어초 제작시 식생에 유리하고, 화학성분 및 비중은 표 1과 같다. The electric furnace oxide slag is excellent in wear resistance, excellent in acid and alkali resistance, and contains a lot of iron, which is advantageous to vegetation when manufacturing artificial reefs, and the chemical composition and specific gravity are shown in Table 1.

상기 CSA 팽창제는 블리딩 현상을 방지하여 수축에 의한 균열발생을 억제하고, 수축되는 비율을 줄여줌으로써 시멘트와 섞여있는 수분이 증발한 후에 응결된 후의 공간 즉 공극이 넓게 형성된다.The CSA swelling agent prevents bleeding and inhibits cracking due to shrinkage, and reduces the shrinkage rate. Thus, the space after the condensation evaporates after the moisture mixed with the cement is evaporated is formed widely.

상기 골재, 시멘트, 물 및 고강도혼합제의 배합비율을 벗어날 경우 강도, 공극율, 투수계수가 낮아지는 등의 문제점이 발생하므로, 본 발명의 배합비율이 최적이라 할 수 있다. 즉, 공극율이 매우 크기 때문에 - 다공성이기 대문에 투수가 잘 되고 미세 플랑크톤이 많이 자랄 수 있는 환경이 된다.If the aggregate ratio of the aggregate, cement, water and the high strength mixture is out of the problem, such as low strength, porosity, permeability coefficient occurs, it can be said that the mixing ratio of the present invention is optimal. That is, because the porosity is very large-because it is porous, it is a good pitcher and the environment that can grow a lot of fine plankton.

상기 성형공정의 몰드는 정육면체로 형성되어, 혼합공정에서 준비된 재료를 채우게 된다.The mold of the molding process is formed of a cube, thereby filling the material prepared in the mixing process.

상기 양생공정은 약 28일간 야적하여 양생하거나, 스팀챔버에서 스팀을 이용하여 양생할 수 있다.The curing process may be cured for about 28 days, or may be cured using steam in a steam chamber.
