나노합성 무기질 폴리머계 표면처리제를 적용한 콘크리트의 내구성능 평가에 관한 실험적 연구
백종명(Baek Jong-Myeong),김은겸(Kim Eun-Kyeum) 한국철도학회 2004 한국철도학회 학술발표대회논문집 Vol.- No.-
In this study, durability of the nano-level inorganic polymer based coatings which can provide a barrier against the ingress of moisture or aggressive ions to concrete is discussed. For the durability evaluation of the coatings, chloride penetration test, accelerating carbonation test, freezing and thawing test, and sulfate ponding test are conducted. As the result of this study, concrete applied nano-level inorganic polymer based coatings has a much higher resistance to the ingress of chloride ion, carbon dioxide, moisture and aggressive acid than plain concrete and epoxy resin based paint by means of cross linking three-dimensional structure with concrete structure.

A concrete structure can be deteriorated by ingress of outside moisture and aggressive agents. To maintain the sound performance of concrete structure during the service life, it needs to protect concrete from ingress of outside moisture and aggressive agents before arising deterioration of concrete. The protection of concrete is possible by surface treatment. In this study, the nano-composite nylon fiber inorganic polymer reinforcing agent based coatings which can provide a barrier against the ingress of outside moisture or aggressive ions to concrete is discussed. For the durability evaluation of the coatings, chloride penetration test, accelerating carbonation test, freezing and thawing test, and surface ponding test are conducted. As the result of this study, the concrete applied the nano-composite nylon fiber inorganic polymer reinforcing agent based coatings has had a much higher resistance to the ingress of chloride ion, carbon dioxide, outside moisture and aggressive acid than plain concrete and concrete structure with epoxy resin based paint by means of cross-linking three-dimensional structure.

콘크리트 구조물의 내구성을 향상하기 위해 개발된 통기성이 개선된 나노합성 폴리머 표면처리제를 도포한 콘크리트의 내구성향상 효과를 평가하기 위해 염분침투, 탄산화, 동결융해 및 화학적 침식 저항성에 대한 실험을 진행하여 기존 표면처리제와 비교․분석하였다. 나노합성 폴리머 표면처리제를 도포한 콘크리트의 염분침투 깊이는 무도포 콘크리트에 비해 약 92% 이상, 수성 에폭시 표면처리제를 도포한 콘크리트보다도 약 70% 이상 감소하였다. 특히 황산 5% 수용액에 침지 실험한 화학적 침식 저항성 실험에서는 침지 12일 이후 무도포 콘크리트와 수성 에폭시 표면처리제를 도포한 콘크리트에서 -4%의 중량감소를 보였다. This experiment was compared and analyzed between the original surface paint through chloride penetration, neutralization, freeze-thaw and chemical corrosion resistance in order to evaluate the effect of increase in durability of the newly modeled nano synthesized polymer paint painted on concrete surface which results improvement on air permeability to increase the durability of concrete structures. Chloride penetration depth of concrete, painted with nano synthesized polymer paint, was decreased more than 92% compared to non-painted concrete and 70% with water-based epoxy painted concrete. Especially, chemical corrosion resistance test set with aqueous solution of 5% sulfuric acid, non-painted concrete and water-based epoxy painted concrete showed weight loss of 4% after dipping for 12 days.

백종명(Baek Jong-Myeong),황영호(Hwang Young-Ho),손정철(Shon Jung-Chul) 한국철도학회 2008 한국철도학회 학술발표대회논문집 Vol.- No.-
Recent interest in the construction sector, rising about the environment and eco-friendly recycled material resources, and increase the development of method But despite these efforts, and the diverse functional and structural changes in the structure can not be an appropriate response to the functional waterproof structural changes in the structures and appropriate response Diversification does not waterproof and functional issues such as durability, and which are occurring due to the structure to secure stability and durability, never sees the conservative economic losses due to import constructability reinforcement situation. Therefore, this study applies to structure the existing waterproof method (hereinafter referred to as structures water-resistant methode), and to review recent issues of environmental pollution and resource waste, and taking on environmental issues, such as Revelation and functional Inorganic mixed in a way to leverage the manufacturing water-resistant material 『 Re Inorganic, functional and environmentally friendly high-viscosity mix asphalt waterproof rubber reinforcements, and taking conservative』 for the characterization and performance assessment to the issues raised by the structure and whether the judge would respond

친환경 연성모르타르와 섬유로드를 이용한 내진보강 방안에 관한 연구
백종명(Baek Jong-Myeong),신민호(Shin min-ho),김한배(Han-Bae Kim),김박진(bag-jin Kim) 한국철도학회 2011 한국철도학회 학술발표대회논문집 Vol.2011 No.10
As the growing concern about environment and earthquake for the concrete structure many seismic rehabilitation and retrofitting methods have recently been studied but they are not coping enough with the changes of structure specificly various problems have been found in seismic rehabilitation method - both in exposure or non exposure - when they are implemented to the underground structure utility conduit water supply facilities underground wall parking lot road pavement and elevated structure etc. This study is about the seismic rehabilitation method using environmentally friendly functional inorganic mortar and resilient material and it is effectively retrofitted seismic performance as it reinforces not only physical strength but also flexural and bond strength from the resilient material and it has been analyzed and evaluated when the environmentally friendly functional inorganic mortar and the resilient material are applied so as to countermeasure the effect of earthquake and viable problems and approved for possibility of various applications and wide use.

Even in case of new materials, materials that are not only harmless for the current global environment but also have high-performance and high-function are sought-after in consideration of the global environmental problems. Moreover, in construction areas where a large amount of cement and concrete are used, the establishment of the recycling technology or transformation into resources and energy materials are being put in place. And also, in a situation where the slow and relaxed city and rural life have a high priority, the need for cement and concrete as environmentally friendly new materials that best suit the emotions in human beings is on the rise and a new way to make good use of cement and concrete as new materials in construction technology should be sought. The recently introduced functional and environmentally friendly concrete is aimed at enhancing health through the adjustments of the body biorhythm using far-infrared. Minerals that contain a great amount of the elements with the frequent occurrence of the infrared among earth minerals and concrete are mixed to use structures or finishing materials, which will tackle the issues of smells, mold and corrosion.

Concrete structure can be deteriorated by ingress of moisture and aggressive agents. To maintain the sound performance of concrete structure during the service life, it needs to protect concrete from ingress of moisture and aggressive agents before arising deterioration of concrete. Protection of concrete is possible by surface treatment. In this study, durability of the functional nano composite inorganic activated carbon based coatings which can provide a barrier against the ingress of moisture or aggressive ions to concrete is discussed.
