Description
본 발명은 알루미늄 산화피막에 의한 콘크리트의 방수, 방식 및 내염을 위한 공법으로서, 더욱 상세하게는 견고하고 수밀한 내식피막을 콘크리트 표면에 형성하여 장기적으로 콘크리트 표면을 중성화 및 염해로부터 보호할 수 있도록 하는 알루미늄 산화피막에 의한 콘크리트의 방수, 방식 및 내염을 위한 공법에 관한 것이다.The present invention is a method for waterproofing, anticorrosion and flame resistance of concrete by aluminum oxide film, more specifically to form a solid and water-resistant corrosion resistant film on the concrete surface to protect the concrete surface from neutralization and salts in the long term It relates to a method for waterproofing, anticorrosion and flame resistance of concrete by aluminum oxide film.
종래 콘크리트 구조물들이 열화(Deterioration)현상을 보이고 있으며, 이로 인하여 발생하는 균열(Crack), 얼룩(Stain), 억수(Spilling)등은 콘크리트 내부철근의 부식과 밀접한 관계가 있다.Conventional concrete structures show deterioration, and cracks, stains, and spillings are closely related to the corrosion of concrete reinforcing bars.
결국 콘크리트 내부의 철근부식은 콘크리트 구조물의 내구성 저하, 균열, 강도 저하 등 치명적인 결과를 초래한다.As a result, reinforcing corrosion inside concrete has fatal consequences such as poor durability, cracking, and low strength of concrete structures.
이러한 콘크리트 구조물의 열화의 주원인은 다음과 같다.The main causes of deterioration of such concrete structures are as follows.
첫째; 중성화(Carbonation) : CO2와 수분이 반응하여 콘크리트내 철근에 급속한 부식을 초래함.first; Neutralization (Carbonation): CO 2 and moisture react to cause rapid corrosion of the steel in the concrete.
둘째; 염기침투(Chloride Intrusion) : 해풍, 해수, 제설용 염화칼슘에 함유되어 콘크리트에 침투하여 급속한 철근부식을 초래함.second; Chloride Intrusion: It is contained in calcium chloride for sea wind, sea water, and snow removal, and it penetrates concrete and causes rapid reinforcement corrosion.
셋째; 알카리-실리카 반응(Alkali-Silica Reaction) : 고알카리성 시멘트가 특정골재가 수분이 있는 상태에서 반응, 팽창하여 콘크리트의 균열을 초래함.third; Alkali-Silica Reaction: High alkaline cement reacts and expands in the presence of certain aggregates in water, causing concrete to crack.
상기 원인중 콘크리트 내부철근 및 표면부식에 가장 치명적인 중성화와 염기침투는 콘크리트 피복을 CO2, 염화물, 수분으로부터 차단시키는 것이 최선의 방법이다.Among the causes, neutralization and base penetration, which are the most lethal to concrete internal reinforcement and surface corrosion, are the best way to shield concrete coating from CO 2 , chloride, and water.
기존의 콘크리트 피복을 보호하는 화학적인 방법에는 발수제도포, 도장(Painting), 방수제 도포등이며 발수제의 도포시에는 수압이 있거나 물이 직접 닿는 곳에서는 적용이 불가능하고 염기 또는 중성화로부터 콘크리트를 보호하는 효과가 전혀없으며 일반적인 도장은 도료의 변성, 변색, 박리등으로 인하여 콘크리트 구조물에 적용시 내구성에 커다란 문제가 있었다.Chemical methods of protecting existing concrete coatings include water repellent coating, painting, and waterproofing.The application of water repellent is not applicable where there is water pressure or in direct contact with water, and it protects concrete from base or neutralization. There is no big problem in durability when applied to concrete structures due to the deterioration, discoloration and peeling of paint.
본 발명은 상기와 같은 종래의 문제점을 해결하기 위하여 안출된 것으로, 견고하고 수밀한 내식피막을 콘크리트 표면에 형성하여 장기적으로 콘크리트 표면을 중성화 및 염해로부터 보호할 수 있도록 하여 콘크리트 구조물의 염해방지는 물론 도심권 구조물의 종성화 및 동절기 살포되는 염화칼슘, 배기가스의 아황산가스 등으로 인한 콘크리트의 열화(Deterioration) 및 내부철근 부식방지를 이루게 하면서 장기적으로 콘크리트 표면을 중성화 및 염해로부터 보호할 수 있는 알루미늄 산화피막에 의한 콘크리트의 방수, 방식 및 내염을 위한 공법을 제공하는데 있다.The present invention has been made to solve the conventional problems as described above, by forming a solid and watertight corrosion resistant coating on the concrete surface to protect the concrete surface from neutralization and salts in the long term, as well as to prevent salt damage of the concrete structure It prevents deterioration of concrete and corrosion of internal reinforcing steel due to the softening of urban structures, calcium chloride and winter sulfur dioxide, and sulfur dioxide of exhaust gas, while protecting the surface of concrete from neutralization and salt damage in the long term. It provides a method for waterproofing, anticorrosion and flame resistance of concrete.
이하 본 발명이 속하는 기술 분야에서 통상의 지식을 가진 자가 본 발명을 용이하게 실시 할 수 있을 정도로 본 발명에 의한 알루미늄 산화피막에 의한 콘크리트의 방수, 방식 및 내염을 위한 공법을 가장 바람직한 실시예를 들어 상세하게 설명하면 다음과 같다.Hereinafter, a method for waterproofing, anticorrosion and flame resistance of concrete by an aluminum oxide film according to the present invention can be easily carried out by a person having ordinary knowledge in the technical field to which the present invention belongs. It will be described in detail as follows.
본 발명에 의한 알루미늄 산화피막에 의한 콘크리트의 방수, 방식 및 내염을 위한 공법은 알루미늄 플레이크(Aluminium Flake) 또는 파우더(Powder)를 접착성 및 탄성이 우수한 1액형 폴리우레탄수지(One-component Poiyurethane co-polymer)또는 이액형 에폭시수지, 용제(Solvent)와 적절한 비율로 혼합하여 적용하기 용이한 액상으로 만들어 콘크리트 표면에 접착하여 산화 알루미늄 피막에 의한 콘크리트 피복 및 내부 철근을 보호하도록 한다.The method for waterproofing, anticorrosion and flame resistance of concrete by aluminum oxide film according to the present invention is a one-component polyurethane resin (One-component Poiyurethane co-) having excellent adhesion and elasticity to aluminum flakes or powders. It is mixed with polymer or two-component epoxy resin and solvent in an appropriate ratio to make it easy to apply, and it adheres to the concrete surface to protect concrete coating and internal reinforcement by aluminum oxide film.
상기 알루미늄 플레이크 함량은 10%내외로 하며 1액형폴리우레탄수지 또는 이액형 에폭시수지는 30% 내외로 혼합하되 적용방법에 따라 점도(Viscosity)를 조절할 수 있으며, 1액형 폴리우레탄수지 또는 이액형 에폭시수지는 접착강도가 40㎏/㎠이상인 고접착성 수지를 이용한다.The aluminum flake content is about 10% and one-component polyurethane resin or two-component epoxy resin can be mixed to about 30%, but can adjust the viscosity (Viscosity) according to the application method, one-component polyurethane resin or two-component epoxy resin Uses a high adhesive resin having an adhesive strength of 40㎏ / ㎠ or more.
또한 경우에 따라서는 상기 혼합액에 티타늄을 더 포함할 수 있다.In some cases, the mixed solution may further include titanium.
이러한 산화 알루미늄 피막에 의한 콘크리트 피복 및 내부 철근의 보호는 알루미늄은 철보다 방응성이 더좋아서 보다 쉽게 산화한다. 따라서 알루미늄은 초기에 피착물보다 더 빨리 부식되어 산화피막을 형성한다.The protection of concrete cladding and internal reinforcement by this aluminum oxide film is that aluminum is more responsive than iron and oxidizes more easily. Thus, aluminum initially erodes faster than the deposit, forming an oxide film.
이 단단하고 얇은 산화 알루미늄 피막은 공기의 침투를 차단하고 내부의 알루미늄층이 더 산화되는 것을 막는다. 알루미늄이 쉽게 산화된다는 것은 아래 반응과 같이 전자를 잘 내어 놓는 다는 것을 의미한다.This hard, thin aluminum oxide film blocks the penetration of air and prevents the inner aluminum layer from further oxidizing. The fact that aluminum oxidizes easily means that electrons can be released as shown below.
AL → Al3++ 3C- AL → Al 3+ + 3C -
즉, 이것은 좋은 환원제 구실을 할 수 있다.In other words, this can serve as a good reducing agent.
산화된 알루미늄 피막은 콘크리트 표면에 견고하고, 내식성 및 방수성이 강한 피막을 형성하여 콘크리트 피복은 물론 내부 철근의 부식 방지에도 탁월한 효과를 발휘한다.The oxidized aluminum film forms a strong, corrosion-resistant and waterproof film on the concrete surface, and has an excellent effect on the corrosion of the internal reinforcing bars as well as the concrete coating.
상기와 같이 얻어진 알루미늄 혼합액을 콘크리트 표면에 도포하여 피막을 형성하는 방법을 설명하면 다음과 같다.Referring to the method of forming a film by applying the aluminum mixture obtained as described above to the concrete surface as follows.
1) 콘크리트 표면으로부터 불순물 및 이물질을 제거한다.1) Remove impurities and foreign substances from the concrete surface.
2) 콘크리트 표면에 브러시, 롤러, 스프레이등의 도구를 이용하여 알루미늄 혼합액을 도포한다.2) Apply aluminum mixture to the concrete surface using a tool such as brush, roller or spray.
3) 도포는 알루미늄플레이크 및 접착수지의 침투가 용이하고 뭉치지 않도록 가능한 얇게, 즉 한번에 100미크론(μ)이 넘지 않게 여러번 도포한다.3) The coating is applied as many times as thin as possible to prevent penetration of aluminum flakes and adhesive resins and not to be aggregated, that is, not more than 100 microns (μ) at a time.
4) 상온에서 대기중에 자연 경화 시킨다.4) It naturally cures in the air at room temperature.
상기와 같이 콘크리트 표면에 도포되어 경화된 산화 알루미늄 피막에 의하여 콘크리트가 보호되기 때문에 종래의 공법과 달리 들뜸, 박리, 변색 등의 문제점이 없어서 장기간의 내구성을 유지한다.As the concrete is protected by the aluminum oxide film applied and cured on the concrete surface as described above, unlike the conventional method, there is no problem of lifting, peeling, discoloration, etc., thereby maintaining long-term durability.
또한 산화된 알루미늄막은 자외선을 반사시켜서 접착수지의 열화 및 변성을 예방하고 콘크리트의 주야간 온도차를 줄여준다.In addition, the oxidized aluminum film reflects ultraviolet rays to prevent deterioration and denaturation of the adhesive resin and to reduce the temperature difference between day and night.
본 발명은 비록 이상에서와 같은 실시예들에 한하여만 설명하였지만, 여기에만 한정되지 않으며 본 발명의 범주와 사상에 벗어남 없이 여러 가지의 변형과 수정이 이루어질 수 있을 것이다.Although the present invention has been described only in the above embodiments, it is not limited thereto and various modifications and changes may be made without departing from the scope and spirit of the present invention.
이상과 같은 본 발명은 알루미늄피막에 의한 콘크리트의 방수, 방식, 내염공법은 견고하고 수밀한 내식 피막을 콘크리트 표면에 형성하여 장기적으로 콘크리트 표면을 중성화 및 염해로부터 보호할 수 있는 공법으로 적용 및 보수가 용이한 경제적인 공법으로 향후 해안지대 콘크리트 구조물의 염해방지는 물론 도심권 구조물의 중성화 및 동절기 살포되는 염화칼슘, 배기가스의 아황산가스등으로 인한 콘크리트의 열화(Deterioration) 및 내부철근 부식방지에 가장 효율적인 사용를 이루게 하는 것이다.The present invention as described above is a waterproof and corrosion resistant method of the concrete by the aluminum film is a method that can be applied and repaired by forming a solid and watertight corrosion resistant film on the concrete surface to protect the concrete surface from neutralization and salts in the long term It is an economical method that makes it most effective in preventing salt damage of concrete structures in coastal areas in the future, as well as deterioration of concrete and corrosion of internal reinforcing steel due to neutralization of urban structures and calcium chloride and sulfur dioxide of exhaust gases in winter. will be.
