  • 누수균열은 상시 콘크리트 구조체의 거동, 물의 성분, 수압, 온도, 화학 물질 등 다양한 환경 요인의 영향이 작용함에 따라 이에 대응할 수 있는 성능을 확보한 보수재료 및 공법이 사용되어야 한다. 본 연구에서는 콘크리트 구조물은 국가적으로 유사한 공학적 특성(배합설계, 사용재료, 시공방법, 유지관리 등)을 가지고 있기 때문에, 누수균열에 대한 보수 접근도 크게 다르지 않을 것으로 보고, 향후 유지관리 전문가들의 공통적 기술 지침의 필요에 따라 자료를 개발하였다.

  • In these days, repair materials for leakage cannot help but being taken in temporary way without any noticeable countermeasure. This kind of repair is socially criticized many times that is defective construction even if tills costs a lot. It was not arrange the standard for performance evaluation test method and quality maintenance for materials, even it has been used various injection repairing agent. In conclusion, We suggest that the test method for repair materials for leakage to establish the leakage repairing technology as increase of structure demand, so that the necessity of the establishment of the quality control standard and the performance testing way on the relevant water-proof seal is increasing a lot to regulate the water-proof technology and the leakage repair technology.

  • In this study, various materials such as epoxy material, urethane material, cement material, and acrylic material are used to solve the water leakage occurring in underground structures. However, in the reality that the durability is insufficient and the effect is insufficient, it is aimed to improve the repairing effect by using acrylics. As a second study, it is confirmed that leachate can be used as a repair material by considering long time under water stability, elongation range test, fatigue resistance test, tube stability test, damage recovery performance ana temperature stability considering leakage environment for polyacrylate. In addition, this material is applied to Expansion Joint to perform leakage repair, and to verify the effect of repairing leakage by monitoring and visual observation of concrete humidification.

  • This study improved the water repair materials of the polyacrylic system applied to concrete structures by controlling expansion, strengthening water resistance, and improving cohesiveness. The improved polyacrylate repair materials were evaluated against the existing products to verify their performance and level of improvement, and applied on-site to the concrete structures that are leaking the improved water. The verification method measured the presence of water leaks and the moisture content of concrete inside. Moisture levels were measured for two months before and after material installation, and at least 0.8 - 1.7% of humidity was reduced after installing polyacrylic resin, and no leakage was found.

  • This technology is a water leak repair technology using composite materials of concrete structures that block leakage of structures by injecting rapid microcement into the face of underground concrete to block water and injecting flexible glycidylacrylate. Rapid micro cement system repair materials are mixed with fine fibers to improve the flexural sensitivity of the material and to form a layer that blocks stabilized water at the back of the structure by allowing rapid and tight spatial filling during injection with high cohesion The glycidylacrylate repair material can control the expansion rate, and the external stress also has the characteristic that the form of the material is not destroyed or separated, which can also be applied to vibrating induced structures that produce repetitive fatigue loads, and has an effective durability in saline, alkali, acid (chloric acid, sulfuric acid, nitric acid).

  • Since water leakage and cracks are not the source of serious problems such as long-term lowering of performance and durability of a stricture, including damages to operating facilities of a structure, damages to internal finishing materials, exhibition, and goods, and pollution of residential environment, they might have led to development of positive coping skills; however, an instant loss of lives or property due to earthquake, explosion, typhoon, or a fire was indeed neglected. In these days, repair materials for leakage cannot help but being taken in temporary way without any noticeable countermeasure. This kind of repair is socially criticized many times that is defective construction even if this costs a lot. It was not arrange the standard for construction methods of sealer of injection type for leakage maintenance, even it has been used various type of construction methods for leakage part. In conclusion, we suggest that the construction methods of sealer of injection type for leakage maintenance for leakage to establish the leakage repairing technology as increase of structure demand. Therefore, it would be possible to provide a stage-by-stage solution by developing systematic research activities among the industry, schools, and research institutes to spread maintenance management techniques globally through technical solution to water leakage and cracks, acquisition of structural safety with prolonged durability for life cycle, reduction of water leakage repair expense s, and so on.

  • This study is a research examining reshaped pattern in the perspective of repairing parts and materials through repairing renovation of registered cultural properties constructed in modern times and results are as followings. Repairing construction of registered cultural properties of Jollanamdo according to parts is shown numerously in the order of roof, walls and windows, and mostly outworn as time passes on and leakage were the main cause of repair. Also when original shape was damaged by previous repair in the past, and this was another reason of repairing. It was surveyed that among the repairing job repair of damage occurred on the part of roofing area including water leakage, corrosion and damage of roofing material, and damage of groove channel were the most main cause of repair. Especially when roof leakage is occurred by outworn of roofing materials, this cause corrosion and damage of materials due to the damage of leakage parts and this cause repeating cycles of worse leakage again and again. Main repairing materials which deform the original shape of registered cultural properties were confirmed as copper plate used on the roof. Copper plate showing high frequency of application which replaces groove slate or cement roofing tile used on the roof before has high durability and anti-corrosion but it is considered improper material to recover original shape.

  • In the reinforced concrete structure, Even if speak that water leakage occurrence is no problem to material, there is a lot of reasons construction factor, material damage by behavior structure, properties of matter change by years and water leakage part by environment condition. so, waterproofing technological consideration should be gone ahead. In this research, we will study about stick performance, concrete surface adhesive, damage and blow. we will check all things and test it. The stick expansion type complex of flexible material passed on result of standard. It is conducive to concrete of durability by waterproofing layer performance demobilitation technology on the water leakage structure for solution of problem and repair

  • 본 연구에서는 지하 콘크리트 구조물의 누수 균열에 사용되는 주입형 누수보수재료의 품질관리 방안으로 규격화된 국제표준 ISO TS 16774 「Part 3 Test method for water(wash out) resistance」와 KS F 4935 「점착유연형 고무 아스팔트계 누수보수용 주입형 실링재」를 이용하여 현재 우리나라 누수보수현장에서 사용하고 있는 주입형 누수보수재료 5계열(합성고무계, 시멘트계, 아크릴계, 에폭시계, 우레탄계) 3종류씩, 총 15종류의 보수재료에 대한 지하 콘크리트 구조물이 처한 지하수의 유동성에 관한 유실 대응력의 안정성을 연구·검토하였다. 그 결과, KS F 4935 규격에서 규정하고 있는 "질량 변화율이 -0.1% 이내"의 성능 기준으로 고찰하면 합성고무계 RG-2, 우레탄계의 UG-1을 제외하고 나머지 13Type 보수재료는 다소 지하수의 유동성에 따른 유실 저항력의 안정화 방안 검토가 필요 할 것으로 판단된다. 본 연구 결과는 콘크리트 구조물의 균열 부위에 사용되는 보수재료의 선정에 있어 기본 지표로 사용가능 할 것으로 판단된다. 또한, 추후에 연구 개발 되는 보수재료의 품질 향상에 반영할 수 있는 기준 자료의 활용을 기대할 수 있다.
