Description
본 발명은 황토(loess) 및 굴(oyster)껍질을 주재(主材)로 한 구조재(주용도: 인공어초, 벽돌, 보도블럭, 방음벽, 경계석, 중앙분리대 등) 및 그 제조방법에 관한 것이다.The present invention relates to a structural member made of loess and oyster shell as a main material (principal use: artificial fish candle, brick, sidewalk block, soundproof wall, boundary stone, median separator, etc.) and a manufacturing method thereof.
통상 일반 시멘트로 제조된 각종의 구조물이나 건축구조물 등의 평균수명은약 40∼50년 정도로 알려져 있으나, 철근 콘크리트로 구축된 구조물의 경우 그 수명은 철근의 산화작용으로 인하여 이 보다 더욱 짧은 것으로 알려져 있다.Generally, the average number of structures or structures made of ordinary cement is known to be about 40 to 50 years. However, in the case of a structure constructed of reinforced concrete, its lifespan is known to be shorter due to the oxidizing action of reinforcing bars.
특히 해수내에 설치되는 인공어초와 같은 구조물은 해수내에서 염분으로 인하여 심재 역할을 위해 구조물 내부에 심어놓은 철근의 산화작용이 더욱 급속히 진전되어 약 4∼5년 정도이면 철근의 산화로 인한 구조물의 파열 및 분리가 이루어지고, 분리된 구조물의 파편과 부식된 철근의 슬러지 등이 해수를 오염시킴은 물론 해양자원인 해초류, 어패류의 번식에까지 위해를 가하고 있는 실정이다.In particular, a structure such as an artificial fish that is installed in the seawater has an oxidation action of the reinforcing bar implanted in the inside of the structure for the core role due to salinity in the seawater more rapidly, and rupture of the structure due to the oxidation of the reinforcing bar takes about 4 to 5 years And segregation of separated structure and sludge of corroded reinforcing steel not only pollute seawater, but also harm the seaweed and the breeding of seafood.
또한 이러한 시멘트로 제작된 인공어초의 경우에는 강알카리 특성을 가지므로 일정기간(약 3개월 정도; 본 발명자가 실험한 바에 의하면 약 1∼2년 정도)이 경과되지 않으면 인공어초를 해수에 투입시 바로 해초류 등이 번식치 못하는 등의 문제점을 가지고 있었던 것이다.In addition, since the artificial fish made from such cement has strong alkaline properties, if the artificial fish is added to the seawater for a certain period (about 3 months or about 1 to 2 years according to the inventor's experiment) And seaweeds were not able to reproduce.
그리고 일반 철근콘크리트 구조물의 경우 압축강도 면에서도 1일 기준 통상약 82.Okg/㎠ 정도밖에 되지 않아 1개월 이상 양생시키지 않으면 각종 구조물로서사용키 어려웠고 특히 단시간의 매우 높은 강도를 가진 대체 구조물의 보완이 필요하였던 것이다.In case of ordinary reinforced concrete structures, it is only about 82.Okg / ㎠ in terms of compressive strength, so it is difficult to use it as various structures unless it is cured for more than one month. In particular, It was necessary.
근자에 들어서는 각종 시멘트의 모르타르(mortar) 압축강도를 향상키 위하여초속경성(超速硬性) 광물을 혼합한 시멘트가 시중에 선보이고 있으나, 이 또한 자연 친화적이지 못하여 상기와 같은 문제점을 안고 있는 것이다.In order to improve the mortar compressive strength of various cements in recent years, cement mixed with ultra fast hard minerals has been introduced in the market, but this is also not environmentally friendly and thus has the above problems.
이에 본 발명에서는 지금까지 각종 구조물의 재료로 사용되었던 시멘트 및 철근콘크리트 등의 문제점을 일소할 수 있는 자연 친화적인 신규한 각종 구조물(예; 인공어초, 벽돌, 보도블럭, 방음벽, 경제석, 중앙분리대 등)의 대체재로서의 구조재와, 상기 구조재의 제조방법을 제공함에 기술적 과제를 두고 본 발명을 완성한 것이다.Therefore, in the present invention, a variety of naturally friendly new structures (for example, artificial fishes, bricks, sidewalk blocks, soundproof walls, economic seats, median seals, etc.) that can solve the problems of cement and reinforced concrete, And the like, and a method for producing the above structural material, and has completed the present invention with a technical problem.

[제조방법][Manufacturing method]
(1) 굴껍질 및 황토의 건조(1) drying oyster shells and loess
굴껍질 및 황토를 약 400℃의 온도에서 건조시킨다.Oyster shell and loess are dried at a temperature of about 400 ° C.

상기와 같은 제조방법으로 본 발명의 구조재를 제조하되, 하기와 같은 점에특히 유의토록 한다.The structural material of the present invention is prepared by the above-mentioned production method, and the following points are particularly noteworthy.
즉, 굴껍질은 반드시 완전건조 및 소성(약 400∼600℃)한 후 분쇄하여 사용토록하며, 굴껍질의 분쇄입도는 1,000 MESH 표준체 통과분을 반드시 사용하여야 하는데, 굴껍질 입자가 미쇄할수록 황토와 비율별 혼합시 소결이 용이하게 되어 제품강도를 향상시킬 수 있다.That is, the oyster shell must be completely dried and calcined (about 400 to 600 ° C) and then used for grinding. The grain size of the oyster shell should be 1,000 MESH standard passing powder. Sintering is facilitated when mixing ratio by weight, and the product strength can be improved.
또한 굴껍질 및 황토 조합시 완전히 혼합이 되도록 교반기 등의 설비장치를구비하여야 하는데, 본 발명자가 분석한 바에 따르면 양자의 혼합이 균일하게 이루어지지 않으면 제품소성 후 강도에 막대한 영향을 미치는 것을 확인하였다.Also, it is necessary to provide an equipments such as a stirrer so as to be completely mixed when the oyster shell and the loess soil are combined. According to the analysis by the present inventor, it has been confirmed that if the mixing of the two is not uniform, the strength after the baking is greatly affected.
굴껍질과 황토의 적정 조합비를 데이터에 따른 물성을 체크해 본 결과 하기의 표 1과 같이 굴껍질의 사용량을 약 4∼6 중량% 정도 첨가시 가장 좋은 물성(즉제품강도, 수축율, 흡수율, 1g-loss)을 가지는 것으로 밝혀졌다. 또한 굴껍질의 사용량을 전기한 비율로 배합시에는 황토성분과 잘 결합 용융되며 제품강도 역시 증가시킨다.As shown in Table 1 below, when the amount of oyster husk used was about 4 to 6 wt%, the best physical properties (i.e., product strength, shrinkage, absorption rate, 1 g- loss. In addition, when the amount of oyster shell used is mixed with the ratio of the oyster shell, the strength of the product is also increased due to the good fusion with the ocher component.
상기 과정에서 굴껍질 사용량을 황토와 배합비를 약 4∼6 중량% 정도로 배합하지만 이 배합비는 중량비이기 때문에 실제로는 상당량의 굴껍질이 사용되어 폐기물을 재활용하는 효과 역시 지대한 것이다.In the above process, the amount of oyster shell used is about 4 to 6 wt% in combination with the loess, but since the blending ratio is a weight ratio, a substantial amount of oyster shell is actually used, and the effect of recycling waste is also great.
본 발명의 발명자는 본 발명의 구조재 시편 물성 테스트를 하기와 같은 실시예로 하여 다음과 같은 결과를 얻을 수 있었다The inventor of the present invention has succeeded in testing the properties of the structural specimen of the present invention as follows:

The loess was dried and then pulverized and separated into 100 MESH standards. The oyster shells were dried and pulverized and separated into 100 MESH standards.
성형몰드는 길이 12cm, 두께 1.5cm 짜리를 각 5개씩 성형하여 사용하되, 성형 수분은 8%, 성형압력은 600kg/㎠으로 하였으며, 성형시편은 400℃ 건조기 함량이 될 때 까지 건조(9hr)하였다.The forming mold was molded by 5 pieces each having a length of 12 cm and a thickness of 1.5 cm. The molding water was 8% and the molding pressure was 600 kg / cm 2. The molded piece was dried (9 hr) .
전기로에서 1250℃의 온도로 약 12시간(hr) 동안 시편을 소성 후 물리적 성질 및, 화학적 성분을 테스트 하였다.The specimens were fired in an electric furnace at a temperature of 1250 ° C for about 12 hours (hr), and physical properties and chemical composition were tested.

(비고: 굴껍질은 참비중이 2.1∼2.6, 부피비중이 0.2∼0.4이며, 화학성분은 CaO가 90% 이상이며 소성온도 800∼900℃에서 CO2를 방출하며, 주로 건축자재, 단열재 및 요업 등에 사용됨).(Note: Oyster shells have a true specific gravity of 2.1 to 2.6, a bulk specific gravity of 0.2 to 0.4, a chemical composition of 90% or more of CaO and emit CO 2 at a calcination temperature of 800 to 900 ° C., and mainly contain building materials, Etc.).
이상에서 상세히 살펴 본 바와 같이 본 발명에서 제공하는 황토 및 굴껍질을주재로 한 구조재는 하기와 같은 다수의 효과를 가진다.As described in detail above, the structural material based on ocher and oyster shells provided in the present invention has a number of effects as described below.
즉 본 발명의 구조재는 기존에 시멘트, 철근콘크리트 등으로 제조되는 각종의 구조물, 즉 인공어초, 벽돌, 보도블럭, 방음벽, 경계석, 중앙분리대 등의 대체재로서 다양하게 활용될 수 있어 산업적 파급효과가 지대하며, 인공어초 등으로 해수에서 사용시 굴껍질과 황토는 흡수력이 강하여 해수중의 각종 부유물 및 오염물질을 흡착하여 해양오염을 급격히 감소시킬 수 있는 것이다.That is, the structural material of the present invention can be widely used as a substitute for various structures made of cement, reinforced concrete and the like, namely, artificial fish meal, brick, sidewalk, soundproof wall, When oyster shells and ocher are used in seawater with artificial fishes, etc., oyster shells and ocher have strong absorbing power, so that they can adsorb various floating matters and contaminants in the seawater and drastically reduce marine pollution.
그리고 본 발명의 구조재를 인공어초로 사용할 경우 그 재질특성이 중성으로바로 친화력이 뛰어나 투입 즉시 각종 해초류와 어패류 등이 기생할 수 있으며, 장기간이 경과되어 일부가 파손된다 하더라도 해양의 오염방지작용은 지속되어 인공어초 본래의 의도에 부합할 수 있는 것이며, 황토에서 방사되는 원적외선은 방사율이 약 75∼78% 정도로 높아 해양살균 효과 및 오염도 감소에 크게 기여할 수 있는등 그 기대되는 효과가 다대한 획기적인 발명이다.When the structural material of the present invention is used as an artificial fish seed, its material properties are neutral and its affinity is immediately favorable. Therefore, various seaweeds and fishes and shellfishes can be parasitized immediately upon input. It can meet the original intention of artificial fish and the far infrared rays radiated from the loess have a high emissivity of about 75 ~ 78%, which can greatly contribute to the effect of marine sterilization and pollution.
