  • In this stduy, we will references to provide reasonable basis for the test environments applicable to the chemical resistance test covered by KS F 4935 『Injection-type Sealing Materials for Water Leakage Crack of Adhesive and Flexible Rubber Asphalt』, analyze the problems with the current test methods in consideration of the features of materials. As a result, we assured more objective data in improved chemical resistance test methods.

  • The concrete structure hasn't perfect waterproofing performance but if it doesn't have a joint part that could isolate a permeability. Concrete structure(communication tunnel and underground structure) has an expansion joint and construction joint. There are a lot of joint type after construction or expansion, shrinkage, vibration, over load, performance of decline etc.. they offer a water of way by variety change. In this reason, It carries in effect a waterproofing work for the concrete structure of waterproofing. but the structure has a behavior that cause a problem by waterproofing layer of damage, heaving phenomenon, temperature of shrinkage. In this study, we will estimate a field of application for Sealer of injection type for leakage maintenance of construction standard on the waterproofing performance.

  • 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.

  • 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.
