Description

마사토를 이용한 인공어초용 흙 블록 제조방법{How to build soil block for the art fish reef with Cray sand}BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to a method for manufacturing a soil block for an artificial fish,

본 발명은, 유해물질을 용출되지 않는 무기결합재를 첨가하여 마사토를 사용한 흙 블록을 제조하는 방법에 관한 것으로 친환경적인 인공어초용 블록을 제조하는 방법에 관한 것이다.The present invention relates to a method for producing an earth block using Masato by adding an inorganic binder which does not dissolve harmful substances, and relates to a method for producing an environmentally friendly artificial fish root block.

인공어초는 바다 속의 생태계 보호를 위한 인공 장치로 인위적으로 바다 속에 투입하여 설치되는 것인데, 연안바다 속에 인공어초가 투입 설치되면 해조류가 번식하게 되고,이로인해 전복, 소라 등이 서식할 수 있으며, 더불어 해조류에 붙어사는 미생물을 먹이로 하는 다른 어류들이 함께 번식할 수 있다. 또한 인공어초는 작은 물고기들이 적으로부터 몸을 숨기거나 산란하는 장소가 될 수 있을 뿐만 아니라, 인공어초에 해조류가 부착 번식하게 되면 갯녹음 현상(해조군락이 소멸하고, 석회조류의 번식으로 바위 표면이 백색 또는 홍색으로 변하는 현상)을 방지할 수 있다.이와 같이, 인공어초는 바다 속 생태계를 유지하는데 매우 유익한 것이다. 이런 이유로 정부에서는 많은 예산을 지원해 가면서 인공어초를 연안 바다 속에 투입, 설치해 오고 있다.그러나 종래 인공어초용 블록의 대부분은 시멘트를 결합제로 사용하여 성형하는 것이어서 그로인해 상당한 문제점이 있었다. 문제점들을 구체적으로 지적하면, 첫째, 종래의 인공어초는 유독성의 6가 크롬이 함유된일반 시멘트, 슬래그 시멘트 또는 플라이애쉬 시멘트를 결합제로 사용함으로써 바다 속 환경을 오염시키고, 둘째, 이러한 시멘트들은 해수의 염해에 취약하기 때문에 시멘트를 결합제로 사용하여 제작된 어초 또는 어초용 블록은 내구성이 약하여, 쉽게 붕괴될 위험성이 상존하며, 셋째, 시멘트를 결합제로 사용하기 때문에 높은 물/시멘트 비율로 인하여 수축율이 높기때문에 어초 또는 어초용 블록에 크랙이 발생하기 쉽다.또한 이러한 단점을 보강하기 위해 건식 제조방법을 적용하여 블록을 제조하는 경우에는,약 100-200톤의 높은 압력으로 성형을 하여야 시멘트의 강도가 보완되는 원인으로 인하여 가해지는 높은 압력 때문에 황토 등의 흙 입자가 파쇄됨으로써 전체적으로 블록의 내구성이 저하되는 현상이 발생하게 된다. 한편, 원적외선이 방출되는 마사토나 황토 등을 사용하게 되면 생물의 생육에 유익하다고 학계에서는 보고되고 있다.An artificial fish is an artificial device for protecting the ecosystem in the sea. It is installed by being artificially put into the sea. When artificial fishes are installed in the coastal sea, seaweeds breed, and abalone and turban can live there. Other fish that feed on the microorganisms that live on them can breed together. In addition, artificial fishes can be a place where small fish hide or scatter from their enemies, and when seaweed attaches to the artificial fishes, it will cause a cone phenomenon (seaweed community disappears and the surface of the rock is white Or a red color) can be prevented. [0034] Thus, artificial fishes are very useful for maintaining an underwater ecosystem. For this reason, the government has been investing a lot of budgets to install the artificial fish in coastal waters, but most of the conventional artificial fishes are formed by using cement as a binder. First, conventional artificial fishes pollute marine environment by using general cement, slag cement or fly ash cement containing toxic hexavalent chromium as a binder. Second, Because of its vulnerability to salting, the block used for cement as a binding agent is weak in durability and easily collapsed. Third, because of the use of cement as a binder, the shrinkage ratio is high due to the high water / cement ratio In order to reinforce these disadvantages, when the block is manufactured by applying the dry manufacturing method, it is necessary to form the block at a high pressure of about 100 to 200 tons to complement the strength of the cement Because of the high pressure applied due to the cause, soil particles such as loess are broken The durability of the block is lowered as a whole. On the other hand, it has been reported in the academia that it is beneficial for the growth of living things if the use of masato or loess such as far-infrared rays is used.

본 발명은 앞서 본 종래 기술들의 결점을 해소하기 위하여 제안된 것으로, 본 발명의 목적은 시멘트 대신에 해수를 오염시키지 않은 무기결합재를 사용하여 인공어초용 흙 블록을 제조하는 방법을 제공하는 것이다.본 발명의 다른 목적은 소성 가공이나 높은 압력에 의한 가압공정이 불필요하며, 초조강형으로 상온에서 1일 만에 목표 강도를 발현하여 생산비용이 저렴하고 생산성도 높은 인공어초용 흙 블록을 제조하는 방법을 제공하는것이다.본 발명의 또다른 목적은 해수(염해)에 대한 저항성이 높아 내구성이 뛰어난 인공어초용 흙 블록을 제조하는 방법을 제공하는 것이다. 그리고 전국적으로 어디에서나 흔하게 구할 수 있는 마사토 및 황토를 경제적으로 활용할 수 있도록 함으로써 자원의 효율성을 높이는 것도 본 발명의 또다른 목적이 될 수 있을 것이다.It is an object of the present invention to provide a method for manufacturing an artificial fish pyramid soil block using an inorganic binder that does not contaminate seawater instead of cement. Another object of the present invention is to provide a method for manufacturing an artificial earthenware soil block having a high strength and low production cost by expressing a desired strength in a day at room temperature without using a plastic working process or a high pressure pressure process, Another object of the present invention is to provide a method for producing an artificial earthenware soil block having high resistance to seawater (salting) and having high durability. It is another object of the present invention to improve the efficiency of resources by making it possible to economically utilize masato and loess that are available everywhere nationwide.

본 발명의 주된 특징으로,친환경적인 마사토와 황토를 주된 자재로 사용한다는 점, 유독 물질이 용출되지 않게 하는 무기결합재를 사용한다는 점, 블록을 성형함에 있어서 고압의 압축을 요하지 않음으로써 오버컴팩션(over-compaction)의 문제가 발생하지 않는다는 점, 블록을 비투수성으로 하여 해수가 블록 내부에 스며들지 못하게 하여 염해에 대한 저항성을 강화시켰다는 점, 그리고 이러한 점들로 인하여 환경 친화적인 인공어초용 흙블록을 제조할 수 있다는 점 등을 들 수 있다.As a main feature of the present invention, the use of environment-friendly marathon and loess as main materials, the use of an inorganic binder to prevent toxic substances from leaching, and the use of overcompaction over-compaction of the block is not caused, the block is made non-transmissive and the seawater is prevented from permeating into the block, thereby enhancing the resistance to salting, and as a result, the environment- It is possible to do it.

본 발명은 국내 토질함량의 50 ％이상인 친환경적인 마사토와 황토를 주된 자재로 사용하고 있고, 친환경 무기결합재를 사용하여 유독 물질이 배출되지 않게 하고있다, 블록을 성형함에 있어서 고압의 압축을 요하지 않음으로써 오버컴팩션(over-compaction)의 문제가 발생하지 않도록 하였으며, 블록을 비투수성으로 하여 해수가 블록 내부에 스며들지 못하게 하여 염해에 대한 저항성을 강화시킨 흙 블록을 제조하는 방법에 관한 것인바, 그 친환경적인 효과와 자원 활용의 효과를 동시에 얻을 수 있는 매우 유익한 것이다.The present invention uses eco-friendly masato and loess which are more than 50% of the domestic soil content, and the environment-friendly inorganic binder is used to prevent the toxic substances from being discharged. Since the high pressure compression is not required in forming the block The present invention relates to a method for producing a soil block which does not cause overcompaction problems and which is made non-watertight to block the seawater from penetrating into the block, thereby enhancing the resistance to salting. It is very beneficial to obtain environment-friendly effect and resource utilization effect at the same time.

보다 생성하는 공정을 상세히 설명하고자 하며, 다음과 같은 공정으로 이루어진다.먼저 무기결합재 제조 단계로 "고로 수쇄 슬래그" 60-70중량％, "CSA계 고강도 혼화재" 10-15중량％, "소석회(생석회)" 5-20중량％, "천연II형 무수석고(α형 반수석고)" 10-20중량％ 및 "백반" 1-5중량％의 혼합물을 분말도를 4,000㎠/g 이상으로 분쇄한 것이다. 상기 혼합물에서, 고로 수쇄 슬래그는 최종 제품인 블록의 강도를 증가시켜 줌과 동시에 염분에 대한 저항성을 높여준다. 고로 수쇄 슬래그를 50∼65 중량％ 으로 사용시 최대의 압축강도를유지할수 있고 가장 이상적인 블록을 제조할 수 있다.또한 CSA계 고강도 혼화재는 에트링자이트(ettringite)라는 치밀한 침상의 결정물의 생성을유도한다.이로 인해 그 속에 함유된 유해물질을 안정화, 고정화하여 유해물질이 외부로 용출되지 않게된다. 이 CSA계 고강도 혼화재를 5∼15 중량％ 의 혼입이 가장 이상적이며,그 이상으로 사용하면 최종 제품인 블록의 압축강도가 떨어지게 된다.또한 ,천연 II형 무수석고(α형 반수석고)는 결합재의 수축을 막아 크랙을 방지하며 속경재의 응결 조절제 역할을 한다. 천연 II형 무수석고의 사용량은 10-20중량％로 함이 바람직하다.최저중량보다 적을 경우 최종 제품에 크랙이 발생할 염려가 있으므로 적정사용량을 준수해야한다.상기 혼합물 중, 소석회(생석회)는 CaO 성분이 60％ 이상 함유되어 있는 것이어야 하고 소석회와 백반을 일정 비율로 미리 배합하여 생산하여 준비하는 것이 필요하다.그 이유는 백반(명반)은 조해성이 높아 공기 중의 습기를 빨아들여 서로 뭉치는 현상을 보이기 때문에, 이를 방지하기 위하여 소석회(생석회)와 미리 배합함으로써 습기에 노출되지 않도록 하기 위해서이다. 이 두 재료는 고로 수쇄 슬래그의 잠재 수경성의 촉진제 역할을 하여 90일 이후에 발현되는 강도 특성을 14일 이내로 촉진시켜 강도발현 및 고정화, 안정화에 도움을 준다. 생석회의 투입량은 5-20중량％가 적합하고, 백반의 투입량은 1-5중량％가 적합하다.상기 혼합물의 분말도를 4,000㎠/g 이상으로 하면 초기 강도를 개선하는 효과가 있다.다음 단계는 전단계에서 제조된 무기결합재를 마사토(또는 마사토의 황토의 혼합물)1 중량부에 전단계에서 제조된 무기결합재 0.15-0.25 중량부로 배합하여, 이에 물을 0.1-0.15 중량부 투입, 혼합하고, 이 혼합물을 소정의 형틀에 넣어 5-15톤의 저압으로 압축하여 성형시키는 단계이다.마사토를 100％ 사용해도 좋고,황토와 혼합하여 사용해도 좋지만 ,마사토와 황토의 혼합물을 사용하는 경우에는 마사토의 사용량이 적어도 55중량％ 이상인 것이 이상적인 배합이다.황토의 사용량이 45중량％ 이상이면 최종 제품인 흙 블록의 강도가 약해지는 문제점이 있다.무기결합재의 사용량이 0.15 중량부 이하이면, 재료의 결착이 약해질 염려가 있고, 0.25 중량부 이상이면 과다 사용이 되어 역효과가 나타날 수 있다. 그리고 사용되는 재료의 성질들을 고려할 때, 물은 0.1-0.15 중량부 사용하는 것이 적합하다.이와 같이 흙과 혼합하는 단계를 거친후 성형된 흙 블록을 통상적인 방법으로 상온에서 양생시켜는 과정을 거친다.이렇게 제조된 흙 블록 제품은 시간의 경과에 따라, 일정 강도에 이르기까지 계속 강도가 상승한다. 본 발명은 친환경적인 마사토와 황토를 주된 자재로 사용하고, 친환경 무기결합재를 사용하여 유독 물질이 배출되지 않게 하고, 저압으로 블록을 성형함으로 고압의 압축을 요하지 않음으로써 오버컴팩션(over-compaction)의 문제가 발생하지 않도록 하고, 블록내부에 해수 스며들지 못하게 하여 염해에 대한 저항성을 대폭 강화시킨 흙 블록을 제조하는 방법에 관한 것이다.60 to 70% by weight of "blast furnace slag ", 10 to 15% by weight of CSA-based high-strength admixture ", and" ) Powder of 5-20% by weight, a mixture of 10-20% by weight of "natural type II anhydrous gypsum (α-hemihydrate)" and 1-5% by weight of "alum" . In this mixture, blast furnace slag increases the strength of the final product block and increases salt resistance. When the blast furnace slag is used in an amount of 50 to 65 wt%, the maximum compressive strength can be maintained and the most ideal block can be produced. Also, the CSA high-strength admixture induces the formation of a dense bed of crystals called ettringite Thereby stabilizing and immobilizing the harmful substances contained therein, so that the harmful substances are not released to the outside. When the CSA-based high-strength admixture is mixed with 5 to 15% by weight, the compression strength of the block, which is the final product, is lowered. When the natural type II anhydrous gypsum To prevent cracking and to act as a curing agent for the hardwood. The amount of the natural type II anhydrous gypsum used is preferably 10 to 20% by weight, and if it is less than the minimum weight, cracks may occur in the final product. It is necessary to prepare a mixture of slaked lime and white algae at a certain ratio in advance and prepare it because the algae are highly deliquescent, In order to prevent it from being exposed to moisture by mixing with slaked lime (quick lime) in advance. These two materials act as a potential hydroponic promoter of blast furnace slag, which promotes the strength characteristics expressed after 90 days to within 14 days, thus helping to develop strength, fixation and stabilization. The amount of the burnt lime is suitably 5 to 20% by weight, and the amount of the alum is suitably in the range of 1 to 5% by weight. When the powdery degree of the mixture is 4,000 cm2 / g or more, Is prepared by mixing 0.11-0.25 parts by weight of water with 0.11-0.25 parts by weight of an inorganic binder prepared in the preceding stage in 1 part by weight of a mixture of the inorganic binder prepared in the previous stage with a mixture of Marato (or a mixture of loess of Maato) Is compressed to a low pressure of 5-15 tons by molding in a predetermined mold and molded. 100% Masato may be used or it may be mixed with yellow soil, but when a mixture of Masato and Yellow soil is used, If the amount of the loess is more than 45% by weight, the strength of the soil block as a final product is weakened. When the amount of the inorganic binder used is 0.15 part by weight Or less, there is a fear that the binding of the material is weakened, and if it is 0.25 parts by weight or more, excessive use may occur and adverse effects may occur. Considering the properties of the materials used, it is preferable to use 0.1 to 0.15 parts by weight of water. After the mixing with the soil, the molded soil block is cured at room temperature in a conventional manner . The soil block product thus manufactured continues to increase in strength over time until reaching a certain strength. The present invention uses an environment-friendly masterbatch and loess as a main material, uses an environmentally friendly inorganic binder to prevent toxic substances from being discharged, forms a block at a low pressure, and does not require high-pressure compression, And a method for manufacturing a soil block in which resistance to salting is greatly enhanced by preventing sea water from penetrating into a block.
