도 1은 본 발명에 따른 중성화 진행 억제 시공방법 공정도로써, 상기 중성화 진행 억제 시공방법 공정도는 다음과 같은 단계로 이루어진다.1 is a process diagram of the neutralization progress suppression construction method according to the present invention, the process diagram of the neutralization progress suppression construction method consists of the following steps.
중성화된 콘크리트면을 연마하는 단계(S10)와, 상기 연마된 콘크리트 표면에 부착된 이물질을 제거하는 단계(S20)와, 상기 이물질이 제거된 콘크리트에 공극충진하는 단계(S30)와, 상기 공극충진된 콘크리트에 침투성 프라이머를 도포하는 단계(S40), 및 상기 침투성 프라이머가 도포된 콘크리트에 아크릴우레탄수지 100 중량부에 무기계포타슘실리케이트수지 5-25 중량부, 실리콘수지 5-35 중량부, 이산화티탄(TiO2) 35-45 중량부, 알루미나(Al2O3) 10-40 중량부, 흑연 10-90 중량부, 가교형폴리스틸렌 5-20 중량부, 탄산칼슘(CaCo3) 5-20 중량부, 기타첨가안료 1-3 중량부, 계면활성제 1-2 중량부로 이루어진 콘크리트 보호 방식재를 도포하는 단계(S50)로 이루어진다.Polishing the neutralized concrete surface (S10), removing the foreign matter attached to the polished concrete surface (S20), filling the voids in the concrete from which the foreign matter is removed (S30), and filling the voids Applying the permeable primer to the concrete (S40), and the inorganic permeate silicate resin 5-25 parts by weight, silicon resin 5-35 parts by weight, titanium dioxide on 100 parts by weight of the acrylic urethane resin TiO 2 ) 35-45 parts by weight, 10-40 parts by weight of alumina (Al 2 O 3 ), 10-90 parts by weight of graphite, 5-20 parts by weight of crosslinked polystyrene, 5-20 parts by weight of calcium carbonate (CaCo 3 ), 1-3 parts by weight of other additives, 1-2 parts by weight of the concrete consists of applying a protective anticorrosive material (S50).
상기 각각의 단계에 대해서 보다 상세하게 설명하면 다음과 같다.Each step will be described in more detail below.
상기 중성화된 콘크리트면을 연마하는 단계(S10)는, 도 2에 도시된 바와 같이 콘크리트(100)를 이용하여 시공이 완료된 구조물의 경우에 시간이 경화하게 되며서 상기 콘크리트(100) 내부에 산소와 자외선이 침투하게 되고 이때 상기 콘크리트(100) 내부에 구축된 철근(200)은 상기 산소, 자외선에 의해서 부식이 발생하고 상기 부식으로부터 콘크리트(100)가 중성화되며 상기 중성화된 콘크리트(100)가 더 이상의 중성화를 억제하기 위하여 우선적으로 작업하는 것이 도 3에 도시된 바와 같이 연마기를 이용하여 중성화된 콘크리트 외부표면을 연마한다.Polishing the neutralized concrete surface (S10), as shown in Figure 2, the time is hardened in the case of the construction is completed using the
또한, 콘크리트를 연마하는 것 자체가 이물질을 제거하지만 완벽히 제거되지 않기 때문에 다음 단계인 S20 단계에서 불과 고압 물을 이용하여 보다 완벽히 제거하는 것이 바람직하다.In addition, since polishing the concrete itself removes foreign substances but is not completely removed, it is preferable to remove them more completely by using only high pressure water in the next step S20.
즉 연마하는 것은 중성화된 콘크리트면을 박리해주는 것이다.In other words, polishing removes the neutralized concrete surface.
상기 연마된 콘크리트 표면에 부착된 이물질을 제거하는 단계(S20)는, 중성화된 콘크리트면을 연마하여도 콘크리트 표면의 미세 구멍 및 미세 틈에 이물질이 존재하기 때문에 이를 제거하여 본 발명 콘크리트 보호 방식재가 잘 부착되도록 하기 위하여 이물질을 제거한다.Removing the foreign matter adhered to the polished concrete surface (S20), even when polishing the neutralized concrete surface, because the foreign matter is present in the fine holes and fine gaps of the concrete surface to remove it well the concrete protective anticorrosive material of the present invention Remove debris to allow adhesion.
특히, 상기 이물질은 세월에 의해서 콘크리트에 형성된 미세구멍에 생기는 바, 이와 같이 생긴 이물질이 유기물인 경우에는 불을 이용하여 이물질을 제거하며, 상기 유기물 이외의 물질인 경우에는 고압의 물로 이물질을 제거하는 것이 바람직하다.In particular, the foreign matter is formed in the micro-pores formed in the concrete over time, if the foreign matter thus formed is an organic material to remove the foreign matter by using a fire, in the case of a material other than the organic material to remove the foreign material with high pressure water. It is preferable.
상기 이물질이 제거된 콘크리트에 공극충진하는 단계(S30)는, 이물질이 제거 된 콘크리트의 표면이 울퉁불퉁한 형태 즉, 공극이 발생되고 상기 발생된 공극에 엑폭시수지로 표면을 매끄럽게 처리한다.Filling the voids in the concrete is removed foreign matter (S30), the surface of the concrete is removed foreign matter, that is, the pores are generated, the surface is smoothly treated with an epoxy resin in the generated voids.
상기 공극충진된 콘크리트에 침투성 프라이머를 도포하는 단계(S40), 상기 불 또는 고압의 물로 이물질을 제거한 이후에 중성화된 콘크리트의 중성화를 억제하기 위하여 도포하는 콘크리트 보호 방식재가 보다 콘크리트에 보다 잘 부착되기 위하여 침투성 프라이머를 도포한다.Applying a permeable primer to the pore-filled concrete (S40), after removing the foreign matter with the fire or high pressure water concrete protection anticorrosive material applied to suppress the neutralization of the neutralized concrete to better adhere to the concrete Permeable primer is applied.
상기 침투성 프라이머는 엑폭시를 바탕으로 제작된 것으로 콘크리트면하고 본 발명 콘크리트 보호 방식재와 더욱 부착력이 좋아지도록 하는 것이다.The permeable primer is to be made on the basis of epoxy to concrete and to improve the adhesion with the concrete protective anticorrosive material of the present invention.
또한 침투성 프라이머는 콘크리트 고유의 특징 중 하나인 공극을 메워준다. 이는 상기 공극을 메워줌으로써 산소와 자외선이 콘크리트 내부에 구축된 철근에 침투되지 않아 상기 철근의 부식을 방지하고 상기 철근 부식을 방지함에 따라 콘크리트의 중성화를 방지한다.Permeable primers also fill voids, one of the unique characteristics of concrete.

상기 기타첨가안료 1-3 중량부는 각종 색상 안료에 해당한다. 따라서, 상기 기타첨가안료 1-3 중량부가 포함됨으로써 콘크리트 고유의 색 이외에 주변 환경과 친화적인 색상을 사용하여 미관에 유리하게 한다.1-3 parts by weight of the other additive pigments correspond to various color pigments. Therefore, 1-3 parts by weight of the other additives are included, so that it is advantageous to the aesthetics by using colors that are friendly to the surrounding environment in addition to the color of the concrete.
상기 계면활성제 1-2 중량부는 상기 기타첨가안료인 색상 안료의 분산을 위해 첨가한다.1-2 parts by weight of the surfactant is added to disperse the color pigment which is the other additive pigment.
한편, 본 발명 콘크리트 보호 방식재는 각종 건축물 중에서 H 빔 같은 철골 구조물의 철골에 직접 도포하여 철골이 부식되는 것을 방지 또는 부식된 철골의 부식진행을 방지하는 것도 바람직하다.On the other hand, the present invention concrete protection anticorrosive material is preferably applied directly to the steel frame of the steel structure, such as H beam among various buildings to prevent the corrosion of the steel frame or corrosion progress of the corroded steel frame.
아울러, 도 4에 도시된 바와 같이 콘크리트와 콘크리트 구조물 사이에 이음역할을 수행하는 철근, 콘크리트와 결합되어 외부에 돌출된 철근, 콘크리트 내부에 삽입되어 표면에 노출된 철근 등과 같이 콘크리트와 결합되어 일부 노출된 모든 철근에 직접 도포하여 철근의 부식을 막음과 동시에 철근과 콘크리트의 이음부분에서 발생되는 콘크리트 중성화를 억제하고 콘크리트의 내구성을 증대한다.In addition, as shown in FIG. 4, some exposure is performed by combining with concrete such as reinforcing bars performing a joint role between the concrete and the concrete structure, reinforcing bars combined with concrete to protrude to the outside, and reinforcing bars inserted into the concrete and exposed to the surface. It is applied directly to all rebars to prevent corrosion of the reinforcing bars and at the same time, it suppresses the neutralization of concrete generated at the joints of reinforcing bars and concretes and increases the durability of concrete.
