Description
본 발명은 콘크리트 구조물에 관한 것으로, 특히 테트라포드나 인공어초와 같이 고중량 및 내부식성이 요구되는 콘크리트구조물의 개량에 관한 것이다.
The present invention relates to a concrete structure, and more particularly to an improvement of a concrete structure such as a tetrapod or an artificial shear which requires high weight and corrosion resistance.
바닷가의 방파제로서는 사석(捨石)이나 테트라포드(tetrapod)가 많이 사용되며, 인공어초는 바닷속 콘크리트 구조물을 놓아서 구조물에 해조가 부착하여서 번식케 하고 그 곳에 어류들이 숨어살거나 산란장이 되도록 하는 것으로, 단위무게가 많이 나가고 내구성이 있으면 제기능을 보다 잘 할 수 있을 것이다. As a breakwater on the beach, a lot of stone and tetrapod are used, and artificial fishes are placed in a concrete structure in the sea so that seaweed attaches to the structure and breeds and hides fishes or spawning places. If you go out a lot and have durability, you can do better.
테트라포드나 인공어초는 대개가 포트랜트시멘트로 대표되는 일반 시멘트와 골재를 이용하여서 콘크리트 구조물을 만들고 있지만, 강력한 태풍이 몰려오거나 해일이 발생하면 테트라포드나 인공어초가 유실되는 경우가 종종있다. Tetrapods and artificial fishes usually make concrete structures using ordinary cement and aggregate, typically portland cement. However, when powerful typhoons or tsunamis occur, it is often the case that tetrapods or artificial fishes are lost.
그러므로 이에 대한 개선책이 요망된다.
Therefore, an improvement measure is desired.
따라서 본 발명의 목적은 테트라포드나 인공어초, 해저케이블덮개 등과 같이 구조물을 고중량 및 내식성을 갖도록 구성하는 해상 콘크리트구조물을 제공함에 있다.
Accordingly, an object of the present invention is to provide a marine concrete structure in which a structure is constructed to have a high weight and corrosion resistance, such as tetrapods, artificial fish shears, and submarine cable covers.
상기한 목적에 따른 본 발명은, 제강슬래그볼 60~90중량%, 개질유황 결합재 8~30중량%, 무기성 분말 충진재 1~10중량%의 구성비율로 용융 혼합하고 목적된 콘크리트구조물로 성형하여서 상기 콘크리트구조물이 3~4의 비중이 되는 고중량 및 내식성을 갖도록 구성함을 특징으로 하는 고중량 및 내식성을 갖는 콘크리트구조물이다. According to the present invention, there is provided a method of manufacturing a steel sheet, which comprises melting and mixing steel slag balls at 60 to 90% by weight, modified sulfur binder at 8 to 30% by weight and inorganic powder filler at 1 to 10% Wherein the concrete structure has a weight of 3 to 4 and a high weight and corrosion resistance.
상기의 콘크리트 구조물에는 테트라포드, 인공어초, 해저 케이블 덮개가 포함됨을 특징으로 한다.
The concrete structure includes tetrapod, artificial fish shear, and submarine cable cover.
본 발명은 제강슬래그볼과 개질유황 결합재 및 무기성 분말충진재를 이용하여서 테트라포드나 인공어초, 해저케이블 덮개 등과 같이 높은 중량을 필요로 하고 부식은 잘 되지 않도록 주로 해양에 관련된 콘크리트구조물을 구현하므로 기존 일반 콘크리트 구조물보다 훨씬 무거우면서도 소금물 등에서도 잘 부식이 되지 않는 이점이 있으며, 환경친화적인 장점도 있다.
The present invention uses a steel slag ball, a modified sulfur binder, and an inorganic powder filler to provide a concrete structure related to marine such as tetrapod, artificial fish cake, submarine cable cover, etc., It is much heavier than concrete structures, but it has the advantages of not being well corroded even in brine, and it is also environmentally friendly.
이하 본 발명의 바람직한 실시 예를 상세히 설명한다.Hereinafter, preferred embodiments of the present invention will be described in detail.
본 발명에서는 테트라포드나 인공어초, 해저케이블 덮개 등과 같이 높은 중량을 필요로 하고 바닷물 등의 물이나 풍압에 부식은 잘 되지 않도록 하는 콘크리트구조물을 구현한다. The present invention implements a concrete structure that requires high weight such as tetrapods, artificial fish shears, submarine cable covers, etc., and is resistant to corrosion of water or wind pressure such as seawater.
이를 위해서, 본 발명에서는 일반 시멘트와 골재를 전혀 사용하지 않고, 그 대신 제강슬래그볼과 개질유황 결합재 및 무기성 분말충진재와 같은 재료를 사용한다. For this purpose, in the present invention, general cement and aggregate are not used at all and instead, materials such as steel making slag balls, modified sulfur binding materials and inorganic powder fillers are used.
본 발명에 사용되는 재료중 하나인 제강슬래그볼은 제철 고로의 1300℃의 용융 슬래그를 별도의 플랜트를 이용해서 급속냉각하는 동시에 강한 바람을 비산시킴으로써 얻을 수 있는 화학적으로 안정된 구형체로서 슬래그 재활용 물질이다. 이러한 제강슬래그볼은 본 발명에서 0.2~5mm 직경 범위로 사용하며 그 비중은 3~4이다. 제강슬래그볼의 비중은 일반 포틀랜트시멘트로 된 콘크리트의 비중(약 2.6)보다 훨씬 커서 중량감이 훨씬 더 나간다. 또 제강슬래그볼은 시중에 유통되는 모래 가격보다 싸며 무공해물질이라는 이점도 있다. The steelmaking slag ball, which is one of the materials used in the present invention, is a chemically stable spherical body that can be obtained by rapidly cooling molten slag at 1300 ° C in a steel blast furnace using a separate plant and scattering strong winds, and is a slag recycling material . The steel making slag balls are used in the present invention in the range of 0.2 to 5 mm in diameter and have a specific gravity of 3 to 4. The specific gravity of the steel slag ball is much larger than the specific gravity of the concrete (2.6) of the ordinary portland cement. Steel slag balls are also cheaper than sand in the market and are also pollution-free.
본원 발명자가 실험을 통해 얻은 것으로 본 발명에서는 고비중이 나가는 제강슬래그볼의 구성비율 범위를 60~90중량%로 한다. 제강슬래그볼의 구성비율이 60중량% 미만이면 목적하는 콘크리트구조물의 자체 무게(단위체적당 무게)와 압축강도가 줄어들고, 그 구성비율이 90중량%를 넘어서면 콘크리트구조물을 구성하는 제강슬래그볼 및 무기성 분말충진재들 간의 결합이 잘 이루어지지 않는데에 그 임계적 의의가 있다. In the present invention, the composition ratio of the steel making slag balls having a high boiling point is 60 to 90% by weight. If the composition ratio of steelmaking slag balls is less than 60 wt%, the weight of the desired concrete structure (weight per unit weight) and the compressive strength are reduced. If the composition ratio exceeds 90 wt%, the steel slag ball and the weapon constituting the concrete structure There is a critical significance in that the bonding between the powdery fillings is not performed well.
또 본 발명에서 사용되는 재료중 개질유황 결합재는 유황 폴리머 시멘트(SPC: sulfur polymer cement), 개질 유황 등으로도 불리워지며, 본 명세서에서는 포틀랜트 시멘트로 대표되어지는 콘크리트구조물의 재질인 일반 시멘트와의 구별될 수 있도록 유황폴리머시멘트 등으로는 언급하지 않고 '개질유황 결합재'로 통일하여 사용한다. 개질유황 결합재는 산 등의 화학성분에 대한 강하고(내화학성), 내부식성과 내수성, 내염성이 좋으며 외압 강도면에도 양호한 특성이 있으며, 본 발명에서는 결합재(binder)로서 이용된다.In addition, the modified sulfur-binding material of the present invention is also referred to as sulfur polymer cement (SPC), modified sulfur, and the like. In the present specification, the term " modified cement " It is not referred to sulfur polymer cement or the like so that it can be distinguished, and it is used as a 'modified sulfur binder'. The modified sulfur-bonded materials are strong against chemical components such as acids (chemical resistance), good in corrosion resistance, water resistance and salt resistance, good in external pressure strength, and used as a binder in the present invention.
개질유황 결합재는 상온 고체이고 120℃ 내외에서 용융되는 가소성수지로서 고가이다. 또 개질유황 결합재는 내화학성, 내부식성, 내염성 등의 특성이 있다. The modified sulfur binder is a plastic resin which is solid at room temperature and melts at about 120 ° C and is expensive. The modified sulfur-bonded materials have properties such as chemical resistance, corrosion resistance, and salt resistance.
본 발명에서는 결합재 역할을 하는 개질유황 결합재의 구성비율 범위를 8~30중량%로 한다.In the present invention, the composition ratio range of the modified sulfuric binder serving as a binder is set to 8 to 30% by weight.
본원 발명자가 수많은 실험을 통해 확인한 결과, 개질유황 결합재는 제강슬래그볼 및 무기성 분말 충진재와 함께 사용시 최소 8중량%이면 콘크리트구조물에서의 내부식성, 내염성의 특성이 발현될 수 있음과 동시에 결합재의 역할도 담당할 수 있었다. 개질유황 결합재의 구성비율이 30중량%를 넘어서면 제강슬래그볼의 비율이 상대적으로 줄어들어서 단위체적당 무게가 고중량이 되기가 어렵다. 본원 발명자는 개질유황 결합재가 8~30중량%범위 내에서 제강슬래그볼 및 무기성 분말충진재를 결합시키는 결합재 역할도 제대로 하고 구조물이 고강도를 유지할 수 있음을 확인하였다.The inventors of the present invention have found through numerous experiments that the modified sulfur binder can exhibit corrosion resistance and salt resistance characteristics in a concrete structure at a minimum of 8% by weight when used together with steel-making slag balls and inorganic powder fillers, I was able to take charge. If the proportion of the modified sulfur binder exceeds 30% by weight, the proportion of steelmaking slag balls is relatively reduced, and it is difficult for the weight per unit volume to become high. The inventors of the present invention have confirmed that the modified sulfur binder can serve as a binder for bonding the steel slag balls and the inorganic powder filler within a range of 8 to 30% by weight and the structure can maintain high strength.
본 발명에서는 제강슬래그볼 사이에 충진될 수 있도록 하기 위해 개질유황 결합재와 함께 무기성 분말 충진재를 함께 사용한다. 본 발명에서 사용하는 무기성분말 충진재의 구성비율은 1~10중량%이다. In the present invention, an inorganic powder filler is used together with a modified sulfur binder to fill the steel slag balls. The composition ratio of the inorganic filler to be used in the present invention is 1 to 10% by weight.
무기성 분말충진재는 정제회(fly ash), 고로슬래그 미분말, 규사 미분말 등이 포함될 수 있으며, 3000~5000㎠/g의 브레인 분말도를 갖는다. 상기 무기성 분말충진재의 분말도가 5000㎠/g를 벗어나 높게되면 혼합 유동성이 떨어져 성형작업성이 떨어지게 하고 분말도가 3000㎠/g 미만으로 떨어지면 압축강도 성능이 떨어진다. The inorganic powder filler may include fly ash, fine blast furnace slag powder, silica fine powder, etc., and has a brain powder of 3000 to 5000 cm2 / g. If the powderiness of the inorganic powder filler is higher than 5000 cm 2 / g, the mixing fluidity is lowered and the molding workability is deteriorated. If the powdering degree falls below 3000 cm 2 / g, the compressive strength performance is lowered.
본 발명에서 무기성 분말충진재는 정제회(fly ash)가 가장 바람직하며, 그 구성비율 1~10중량%는 재료혼합시 가열로 융용되는 개질유황 결합재의 적정한 반죽점도 유지와 제강슬래그볼 사이에 충진밀도와 압축강도 유지에 합당한 임계적 범위이다. The inorganic powder filler in the present invention is most preferably a fly ash, and the composition ratio of 1 to 10% by weight is suitable for maintaining a proper kneading viscosity of the modified sulfur binder to be melted by heating during mixing of materials, It is a critical range to maintain density and compressive strength.
본 발명에서는 고중량 및 내식성이 있는 목적하는 콘크리트구조물 예컨대 테트라포드, 인공어초, 해저 케이블 덮개를 제조하기 위해서, 제강슬래그볼 60~90중량%, 개질유황 결합재 8~30중량%, 무기성 분말 충진재 1~10중량%의 구성비율로 용융 혼합하되, 제강슬래그볼, 개질유황 결합재와 무기성분말 충진재 각각을 미리 가열한 상태로 교반기에 투입하고, 교반기에서 개질유황 결합재가 용융된 상태로 교반 혼합한다. 이렇게 얻은 혼합 반죽물을 거푸집과 같은 성형틀에 넣어 목적하는 콘크리트구조물을 성형하며, 그후 상온에서 굳게해서 그 콘크리트구조물을 완성한다. In the present invention, in order to produce a desired concrete structure having a high weight and corrosion resistance, for example, tetrapod, artificial fish and submarine cable cover, a steel slag ball is used in an amount of 60 to 90 wt%, a modified sulfur binding material 8 to 30 wt% 10% by weight. The steelmaking slag balls, the modified sulfur binder and the inorganic filler are respectively charged into a stirrer while being heated, and the modified sulfur binder is stirred and mixed in a molten state in an agitator. The mixed material thus obtained is put into a mold such as a mold to form a desired concrete structure, and then solidified at room temperature to complete the concrete structure.
상기와 같이 완성된 본 발명의 콘크리트구조물은 전체 비중이 3~4되므로 일반 포틀랜트시멘트로 된 콘크리트의 비중(약 2.6)보다 훨씬 커서 중량감이 훨씬 더 나가며, 내식성을 가짐은 물론이고 제작단가가 저렴하고 친환경적인 구조물이 된다.
Since the concrete structure of the present invention thus completed has a total specific gravity of 3 to 4, it is much larger than the specific gravity (about 2.6) of the concrete made of ordinary portland cement, so that the weight feeling is much greater and the production cost is low And becomes an environmentally friendly structure.
상술한 본 발명의 설명에서는 구체적인 실시 예에 관해 설명하였으나, 여러 가지 변형이 본 발명의 범위에서 벗어나지 않고 실시할 수 있다. 따라서 본 발명의 범위는 설명된 실시 예에 의하여 정할 것이 아니고 특허청구범위 및 그 특허청구범위와 균등한 것에 의해 정해 져야 한다.
