본 발명은 분급된 페로니켈 슬래그 잔골재를 사용한 초속경 콘크리트 교면포장 조성물 및 이를 이용한 교면포장 시공방법에 관한 것으로, 보다 상세하게는 초속경시멘트 100중량부와; 입자크기 1.2~2.5mm로 분급된 페로니켈슬래그 잔골재 200~250중량부와; 셀룰로오스계 증점제, 아크릴계 증점제 및 폴리에틸렌 옥사이드계 증점제가 각각 동일중량비로 혼합된 혼합증점제 5~20중량부와; 물 50~80중량부;를 포함하여 조성되어 혼합증점제에 의한 미세공극제거효과에 따른 시멘트 결합력 향상, 방수, 균열 저항성 및 염해저항성을 향상시키기 위한 분급된 페로니켈 슬래그 잔골재를 사용한 초속경 콘크리트 교면포장 조성물 및 이를 이용한 교면포장 시공방법에 관한 것이다.The present invention relates to a super-hard concrete concrete surface paving composition using a classed ferronickel slag fine aggregate and a method of constructing the surface using the same, more specifically, 100 parts by weight of ultra-fast diameter cement; 200 to 250 parts by weight of fine aggregate of ferronickel slag classified in particle size of 1.2 to 2.5 mm; 5 to 20 parts by weight of a mixed thickener in which the cellulose thickener, the acrylic thickener, and the polyethylene oxide thickener are mixed in the same weight ratio; It is composed of 50 ~ 80 parts by weight of water. It is composed of mixed thickeners to improve cement bonding strength according to the effect of removing micropores, and waterproof, crack resistance, and salt resistance. The present invention relates to a composition and a method for constructing a bridge surface using the same.
일반적으로 교량이란 하천, 해안, 도로 등의 상부를 지나갈 수 있도록 가설된 고가 구조물을 총칭하는 것으로, 이러한 교량의 표면에는 차량 등이 원활하게 통행할 수 있도록 포장공사를 함으로써 교면 포장층을 형성한다.In general, a bridge is a collective term for an elevated structure that is built to pass over the upper part of rivers, coasts, and roads. The surface of the bridge is formed by paving the pavement layer so that vehicles can pass smoothly.
교면 포장은 교통 하중을 직접 전달하는 부분으로서, 반복되는 교통하중에 적합한 강도 및 균열저항성을 가져야 하고 빗물 등의 수분에 노출되어 있는 관계로 방수 성능을 가질 것이 요구되며 특히, 염화물이온의 침투에 의해 철근이 부식되는 것을 방지하기 위하여 낮은 염소이온 투수성을 가질 것이 요구된다.The bridge pavement is a part that directly transmits traffic loads, and should have strength and crack resistance suitable for repeated traffic loads, and is required to have waterproof performance because it is exposed to moisture such as rainwater. It is required to have low chlorine ion permeability to prevent corrosion of the reinforcing bar.
그러나, 교면 포장은 중차량 통행에 따른 소성 변형과 충격에 따른 파손, 지역적 특성에 따른 기후 변화, 동결 융해에 대한 영향, 장대 교량의 경우 처짐 진동에 따른 영향, 우수 및 염소 이온 등의 침투로 인한 철근의 부식 및 이에 따른 교량 상판 콘크리트의 손상 촉진 등의 원인에 의해 손상이 일어나기 쉽다.However, the bridge pavement is due to plastic deformation due to heavy vehicle traffic and damage due to impact, climate change due to regional characteristics, impact on freezing and thawing, and impact due to deflection vibration in the case of long bridges, rainwater, and penetration of chlorine ions Damage is likely to occur due to causes such as corrosion of reinforcing bars and thus damage to the bridge deck concrete.
이와 같이 교면 포장에 손상이 발생하는 경우, 파손된 부분을 제거하고 그 부분을 보수해야 하는데, 특히 교량의 보수에 있어서는 장기간 교량 폐쇄시 교통 체증이 발생하게 되므로 교량 보수 공사는 빠른 시간에 신속하게 이루어질 필요가 있다. In the case of damage to the pavement of the bridge, it is necessary to remove the damaged part and repair the part. In particular, in the repair of the bridge, traffic jams occur when the bridge is closed for a long time, so the bridge repair work can be done quickly and quickly. There is a need.
또한, 기존 포장과의 접합이 우수해야 하고, 장기 강도 및 내구성이 우수하여 보수 효과가 장기간 유지되어야 한다.In addition, the bonding with the existing packaging must be excellent, and the long-term strength and durability are excellent, so that the maintenance effect must be maintained for a long time.
그러나, 기존의 교량 보수 공법은 주로 아스팔트 덧씌우기, 폴리머 콘크리트 박층 포장 보수 공법 등이 이용되고 있으나 작업 시간이 오래 걸리고 기존 포장과의 접합이 열악하며 강도 및 내구성이 크지 않아 보수 효과가 장기간 유지되지 못하는 면이 있었다However, the existing bridge repairing method mainly uses asphalt overlaying, polymer concrete thin layer pavement repairing method, etc., but it takes a long time to work, poor bonding with existing pavement, and strength and durability are not great, so the repair effect cannot be maintained for a long time. There was cotton
이러한 문제점들을 해결하기 위하여, 최근에는 교량 상판에서 부식이나 침식이 많이 일어나는 부위에 적용되는 것으로, 보통 콘크리트 배합시에 SBR(Styrene Butadiene Rubber) 라텍스를 첨가한 초속경 폴리머 재질 콘크리트로서 라텍스 개질 콘크리트(LMC : Latex Modified Concrete)가 개발되어 사용되고 있다.In order to solve these problems, recently, it is applied to a site where a lot of corrosion or erosion occurs on the bridge deck, and it is usually a super-hard polymer material added with SBR (Styrene Butadiene Rubber) latex when mixing concrete, latex modified concrete (LMC : Latex Modified Concrete) has been developed and used.

한편, 스테인레스 스틸의 주원료인 페로니켈 생산 공정에서 페로니켈 슬래그가 발생하고 있다. 스테인레스 스틸의 주원료인 페로니켈은 전기로 또는 로터리 킬른에서 제련하여 생성되며, 이때 페로니켈 슬래그가 필수적으로 발생된다. 보통 니켈 1톤당 약 30톤의 슬래그가 발생하는 것으로 알려져 있으며, 국내에서 발생되는 페레니켈 슬래그는 년간 약 200만톤으로 향후 500만톤으로 증가되리라 예상되나, 페로니켈 슬래그의 재활용은 미미한 수준으로 단순 매립하고 있는 실정이다.

The main raw material of stainless steel, ferronickel, is produced by smelting in an electric furnace or a rotary kiln, and ferronickel slag is essentially generated. Normally, it is known that about 30 tons of slag are generated per ton of nickel, and the perennial slag generated in Korea is expected to increase to 5 million tons in the future, about 2 million tons per year, but recycling of ferronickel slag is simple to landfill.

이하에서는 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자가 용이하게 실시할 수 있도록 본 발명의 실시예 및/또는 도면을 통하여 상세히 설명한다. 그러나 본 발명은 여러 가지 상이한 형태로 구현될 수 있으며, 여기에서 설명하는 실시예 및/또는 도면에 한정되지 않는다.Hereinafter, embodiments of the present invention and / or drawings will be described in detail so that those skilled in the art to which the present invention pertains may easily practice. However, the present invention may be implemented in various different forms, and is not limited to the embodiments and / or drawings described herein.
우선, 본 발명의 분급된 페로니켈 슬래그 잔골재를 사용한 초속경 콘크리트 교면포장 조성물은 초속경시멘트 100중량부와; 입자크기 1.2~2.5mm로 분급된 페로니켈슬래그 잔골재 200~250중량부와; 셀룰로오스계 증점제, 아크릴계 증점제 및 폴리에틸렌 옥사이드계 증점제가 각각 동일중량비로 혼합된 혼합증점제 5~20중량부와; 물 50~80중량부;를 포함하여 조성된다.First, the super fast-hard concrete bridge surface packaging composition using the classified ferronickel slag fine aggregate of the present invention comprises: 100 parts by weight of the super fast cement; 200 to 250 parts by weight of fine aggregate of ferronickel slag classified in particle size of 1.2 to 2.5 mm; 5 to 20 parts by weight of a mixed thickener in which the cellulose thickener, the acrylic thickener, and the polyethylene oxide thickener are mixed in the same weight ratio; And 50 to 80 parts by weight of water.
일반적으로, 천연 잔골재는 지속적으로 천연자원에 의해 환경 파괴에 대한 문제를 가지고 있어 수급 및 사용에 대한 어려움이 있고, 천연 잔골재를 대체하는 산업부산물로 순환골재는 높은 흡수율에 의한 콘크리트의 내구성에 영향을 미친다.In general, natural fine aggregate has a problem of environmental destruction by continuous natural resources, making it difficult to supply and use. As an industrial by-product that replaces natural fine aggregate, recycled aggregate affects the durability of concrete due to its high absorption rate. Crazy
상기 천연골재 및 순환골재의 대체재로서, 페로니켈 슬래그는 제강 슬래그처럼 팽창에 문제가 되는 프리 석회 및 마그네슘이 존재하지 않아 팽창에 대한 안정성이 있는 것으로 보고되고 있으며, 특히 입자별로 규사 5, 6호사, 즉 1.2-2.5mm는 연마사로 많이 사용되고 있다.As a substitute for the natural aggregate and the circulating aggregate, ferronickel slag has been reported to have stability against expansion due to the absence of free lime and magnesium, which are problematic for expansion, such as steel slag. That is, 1.2-2.5mm is widely used as an abrasive.
이는 페로니켈 슬래그가 일반 슬래그에 비해 높은 경도를 가지고 있어 연마사로 사용이 가능한 것이고, 또한 일반 골재와 비슷한 밀도인 2.9-3.1의 가지고 있어 제강 슬래그에 비해 비중이 낮아 재료 분리가 일어나지 않으므로 콘크리트용 잔골재로 사용이 가능하다.This is because ferronickel slag has a higher hardness than ordinary slag, so it can be used as an abrasive.It also has a density similar to that of ordinary aggregate, 2.9-3.1, so it has a lower specific gravity than steel slag, so it is not used as a fine aggregate for concrete. It can be used.
