Description
본 발명은 운모가루 및 플라스틱 섬유를 포함하는 초속경 개질 콘크리트 조성물 및 이를 이용한 도로포장 시공방법에 관한 것으로, 보다 상세하게는 초속경 시멘트 결합재, 폴리머 개질제, 운모가루 및 플라스틱 섬유를 포함하는 초속경 개질 콘크리트 조성물 및 이를 이용한 도로포장 시공방법에 관한 것이다.The present invention relates to a super-fast-hardening modified concrete composition containing mica powder and plastic fibers and a road pavement construction method using the same, and more particularly, to a super-fast-hardening modified concrete composition containing an ultra-fast-hardening cement binder, a polymer modifier, mica powder and plastic fibers It relates to a concrete composition and a road pavement construction method using the same.
종래의 교량의 교면 포장공법은 아스팔트 콘크리트를 이용한 교면 포장공법이 주로 시행되어져 왔다. 하지만 아스팔트 콘크리트를 이용한 교면 포장공법은 모두 투수성을 나타내기 때문에 교량 바닥판의 철근 콘크리트를 보호하기 위하여 교면포장에 앞서, 방수층을 설치하도록 되어 있어, 시공 상의 어려움과, 시공 후 방수층의 들뜸현상이 발생되고, 소성변형 등으로 인해 평균 5년마다 절삭하여 재포장하게 되므로 사회적, 경제적 부담이 되어왔다. As for the conventional bridge pavement method, the bridge pavement method using asphalt concrete has been mainly implemented. However, since all bridge pavement methods using asphalt concrete exhibit water permeability, a waterproof layer must be installed prior to bridge pavement to protect the reinforced concrete of the bridge deck, which causes difficulties in construction and lifting of the waterproof layer after construction. It has become a social and economic burden because it is cut and repacked every five years on average due to plastic deformation.
이와 같은 아스팔트 콘크리트 교면포장의 경우에는 재시공시 방수층이 파손되어버려 방수기능을 상실하게 되어 교량 바닥판 콘크리트에 염화물 이온이 침투되어 철근의 부식을 촉진시키는 결과를 초래하게 되어, 교량 바닥판 콘크리트의 내구성을 저하시키는 주요한 원인으로 대두되었다.In the case of such asphalt concrete bridge pavement, the waterproof layer is damaged during re-construction, and the waterproof function is lost, resulting in the penetration of chloride ions into the bridge deck concrete to accelerate the corrosion of the steel bars, resulting in the durability of the bridge deck concrete. emerged as a major cause of the decline in
이러한 문제점을 해결하기 위해 국내에서는 합성고무 라텍스, 아크릴 폴리머 등을 이용한 폴리머개질 콘크리트 교면포장 공법이 개발되어 활용되어지고 있다. 이와 같은 기술로는 대한민국 특허 제 10-0313599호 “불투수성 교량 표면 포장용 개질 콘크리트”가 있다. 이 기술은 콘크리트의 배합 시 합성고무 라텍스(SBR)의 고형분이 콘크리트 내부에 골고루 분산되어 폴리머 피막을 형성함으로서 콘크리트의 휨인성 및 부착강도를 향상시키며, 염소이온의 확산을 크게 막아 준다는 장점을 가지고 있다. 하지만 경화시간이 상대적으로 느린 보통 포틀랜드 시멘트를 사용함으로서, 양생기간이 2주 이상 필요하므로 기존 교량의 보수용 교면포장에는 적합하지 않다.In order to solve these problems, a polymer-modified concrete bridge pavement method using synthetic rubber latex, acrylic polymer, etc. has been developed and used in Korea. As such technology, there is Korean Patent No. 10-0313599 “Modified Concrete for Impermeable Bridge Surface Pavement”. This technology has the advantage that the solids of synthetic rubber latex (SBR) are evenly dispersed inside the concrete when mixing concrete to form a polymer film, thereby improving the flexural toughness and adhesive strength of the concrete and greatly preventing the diffusion of chlorine ions. . However, since normal Portland cement, which has a relatively slow hardening time, is used, a curing period of more than 2 weeks is required, so it is not suitable for bridge pavement for repair of existing bridges.
이를 개선한 기술로는 대한민국 특허 제 10-0537953호 “라텍스개질 초속경 콘크리트 조성물의 제조방법”과 대한민국 특허 제 10-0873391호 “속경성 콘크리트 조성물, 그 제조방법 및 속경성 콘크리트 조성물을 이용한 콘크리트의 포장 보수공법”등이 있다. 이 기술들은 긴급보수에 적합하도록, 초속경 시멘트를 사용하고, 개질용 폴리머로서 합성고무 라텍스 또는 아크릴 개질 에멀젼 등을 사용하여 물과 혼합 후 3~4시간 이후에 21MPa를 발현함으로서 빠른 교통개방이 가능하고, 콘크리트내의 공극사이에 폴리머 필름이 형성됨으로서 부착성, 휨인성, 내동결융해저항성, 투수저항성, 방수성 등이 향상되는 효과를 얻을 수 있다.Techniques that have improved this include Korean Patent No. 10-0537953 “Method for Manufacturing Latex Modified Ultra-fast-setting Concrete Composition” and Korean Patent No. 10-0873391 “Fast-setting concrete composition, its manufacturing method, and concrete using fast-setting concrete composition” Pavement Repair Method”, etc. To be suitable for emergency repairs, these technologies use ultra-fast cement and use synthetic rubber latex or acrylic modified emulsion as a polymer for modification, and express 21MPa 3 to 4 hours after mixing with water, enabling rapid opening of traffic. And, as a polymer film is formed between the pores in the concrete, the effect of improving adhesion, flexural toughness, resistance to freezing and thawing, resistance to water permeability, waterproofness, etc. can be obtained.
그러나 이와 같은 기술은 재료의 제반 물리적인 특성은 우수하지만 모바일 믹서와 같은 특수한 전용 시공 장비를 사용해야만 하는 제약을 가지고 있다. 즉, 폴리머 개질 초속경 콘크리트의 작업가능 시간이 30분 정도로 매우 짧은 특성을 가지고 있어, 일반 레미콘과 같이, 레미콘 공장에서 배합하여 운반할 수가 없기 때문에 현장에서 바로 배합하여 타설할 수 있도록 이동이 가능한 모바일 믹서를 사용하여 시공하고 있다. 모바일 믹서는 1시간당 7m3의 콘크리트를 현장에서 배합 할 수 있기 때문에, 단 시간에 시공할 수 있는 면적이 적을 수밖에 없으며, 정확한 재료의 계량이 어려워 콘크리트의 품질관리가 어렵고, 가장 큰 문제점은 배합에 필요한 원재료인 초속경시멘트, 잔골재, 굵은골재, 폴리머, 물 등을 현장에 있는 모바일 믹서로 운반해야 하기 때문에 교면포장 공사를 하는데 있어 번거로움이 있어, 시공성을 떨어뜨리는 요인으로 작용하고 있다. 이러한 문제점들은 교량의 긴급보수공사에 있어서 상당한 원가상승 요인을 제공하기 때문에 시공비용이 매우 비싸, 해마다 공사비용이 크게 증가하고 있는 실정이다However, this technique has excellent physical characteristics of the material, but has a limitation in that special dedicated construction equipment such as a mobile mixer must be used. In other words, since the workable time of polymer-modified super-fast-hardening concrete is very short, about 30 minutes, unlike general ready-mixed concrete, it cannot be mixed and transported at the ready-mixed concrete factory. It is applied using a mixer. Since the mobile mixer can mix 7m 3 of concrete per hour on site, the area that can be constructed in a short time is inevitably small, and it is difficult to control the quality of concrete because it is difficult to accurately measure materials, and the biggest problem is in mixing. Since the necessary raw materials such as ultra-fast cement, fine aggregate, coarse aggregate, polymer, and water must be transported to the mobile mixer on site, there is a hassle in the bridge pavement construction, which is acting as a factor that lowers the workability. Since these problems provide a significant cost increase factor in the emergency repair work of bridges, the construction cost is very high, and the construction cost is greatly increasing every year.
한편, 섬유보강콘크리트는 콘크리트의 인장강도와 균열에 대한 저항성을 높이고 인성을 개선시킬 목적으로 콘크리트에 각종 섬유를 보강시켜 만든 콘크리트로, 최근 폐플라스틱의 활용으로 탄소배출을 줄이자는 연구가 활발히 진행되고 있다. 하지만 섬유보강콘크리트 일반콘크리트에 비해 열전도율이 높아지는 문제점으로 인해 교면포장에 사용 시 기존 콘크리트와의 부착단면에서 온도 차이에 의한 수평전단력이 크게 발생되기 때문에 사용이 기피되고 있다.On the other hand, fiber-reinforced concrete is concrete made by reinforcing various fibers in concrete for the purpose of increasing the tensile strength and crack resistance of concrete and improving toughness. there is. However, due to the problem that the thermal conductivity of fiber-reinforced concrete is higher than that of general concrete, when used for bridge pavement, horizontal shear force caused by the temperature difference is large at the attachment section with the existing concrete, so its use is avoided.
이에 인장강도를 증진시켜 내구성을 확보하고, 부착단면에 발생되는 수평전단력을 최소화시켜 기존 콘크리트와 일체화 거동을 할 수 있는 라텍스를 첨가한 초속경 콘크리트 교면방수 시공기술을 필요로 하고 있다.Accordingly, there is a need for a super-fast concrete bridge surface waterproofing construction technique with the addition of latex capable of securing durability by increasing tensile strength and minimizing the horizontal shear force generated at the attachment section to perform integrated behavior with existing concrete.
또한, 화석연료연소의 유한한 산물인 질소산화물은 대기 오염을 포함한 환경 및 인간의 건강 문제인 산성비, 오존 고갈, 폐질환 등을 일으키는 원인인데, 최근 세계 경제의 급속한 성장과 함께 교통의 발달로 인해 도로교통이 증가하면서 질소산화물의 방출 문제가 날로 심각해지고 있다.In addition, nitrogen oxide, a finite product of fossil fuel combustion, is a cause of environmental and human health problems including air pollution, such as acid rain, ozone depletion, and lung diseases. As traffic increases, the problem of emission of nitrogen oxides is becoming more serious day by day.
이를 해결하기 위해 많은 연구와 개발이 이루어지고 있는데, 그 중 대표적인 것이 촉매반응을 일으키는 광촉매다. 광촉매는 빛을 받으면 강력한 산화력이 발생하며, 이 작용으로 유해물질을 물과 탄산가스로 변환하여 무독, 무취의 물질로 분해하는 원리이다. 광촉매로 사용되는 대표적인 물질은 나노크기를 갖는 이산화티탄(TiO2)이다.In order to solve this problem, many researches and developments are being conducted, and a representative one among them is a photocatalyst that causes a catalytic reaction. The photocatalyst generates strong oxidizing power when it receives light, and this action converts harmful substances into water and carbon dioxide gas and decomposes them into non-toxic and odorless substances. A typical material used as a photocatalyst is titanium dioxide (TiO 2 ) having a nano size.
하지만 이산화티탄은 생산에 많은 공정이 들어가 콘크리트에 사용되기에는 경제적으로 불리한 위치에 있어 실험적 차원에서는 도입되고 있으나 아직 교면포장 등에는 널리 사용되고 있지는 않고 있다. 따라서 실용적이면서 이산화티탄과 동일한 효과를 나타낼 수 있는 소재에 대한 연구 및 개발이 필요한 실정이다.However, titanium dioxide is in an economically unfavorable position to be used in concrete because many processes are involved in its production. Therefore, it is necessary to research and develop materials that are practical and can exhibit the same effect as titanium dioxide.
