본 연구에서는 지하 콘크리트 구조물의 누수 균열에 사용되는 주입형 누수보수재료의 품질관리 방안으로 규격화된 국제표준 ISO TS 16774, Part 2 Test method for chemical resistance를 이용하여 현재 우리나라 누수보수현장에서 사용하고 있는 주입형 누수보수재료 2계열 (합성고무계, 시멘트계), 3종류 씩, 총 9 종류의 보수재료에 대한 지하 콘크리트 구조물이 처한 화학적 환경의 저항 안정성을 연구·검토하였다. 그 결과, 합성고무계는 RG-3를 제외하고, 산에 대한 저항력을 높일 수 있는 재료적 검토가 필요하고, 시멘트계는 수산화나트륨, 염화나트륨에 대한 저항을 높일 수 있는 재료적 검토의 필요성이 확인되었다. 이러한 결과는 콘크리트 구조물의 화학적 환경에서의 보수재료 선정 시 기본 지 표로 사용가능 할 것으로 판단된다. 또한, 추후에 연구 개발 되는 보수재료의 품질 향상에 반영할 수 있는 기준 자료의 활용을 기대할 수 있다.

This paper analyzes the different expansion properties of various acrylic waterproofing repair materials and draws a conclusion on stable leakage repair measures based on the test results.

This study is based on a survey conducted to understand the current problems of water leakages in underground structures. According to the overall results, 55.7% of the respondents replied that water leakage problems is serious and all replied that a preventative measure is absolutely necessary.

Waterproofing materials applied in underground structures are commonly exposed to environmental factors such as rain water, vibration, structural movement. Particularly in the case of rain waters, the pollutants and chemical substances penetrate into the waterproofing layer surface and cause complex degradation. Approaching this problem with only conventional leakage preventative measures may prove difficulties in solving it. In this regard, 3 dimensional material evaluation methods (waterproofing system structure) should be employed over 2 dimensional methods, and a testing method that allows the simultaneous testing of various degradation conditions found in underground environments is necessary.

현재 대형 빌딩이나 공동주택에 건설되는 지하구조물은 건조수축, 시공이음, 폼타이부 등에서 콘크리트 균열로 인한 누수가 많이 발생되고 있다. 누수가 발생하게 되면 구조물의 지하공간은 결로, 곰팡이 등이 발생되어 지하 환경을 악화시키고 구조물의 콘크리트로 흡수되 면 철근의 부식 등을 유발하여 구조물의 안전을 위협한다. 이는 지하구조물의 사용과정에서 장기적인 쾌적성과 구조물에 안전성이 고려되지 않은 설계와 시공의 결과이며 누수 하자에 대하여 유도배수처리로 대응하기 때문에 근본적인 누수보수가 이루어지지 않아 지하구조물은 항시 누수를 허용하고 있는 실정이다. 따라서 본 연구에서는 지하에 적용되는 방수공법을 내방수와 외방수로 분류하고 이를 바탕으로 지하구조물 과 유사한 간이시험체를 제작하였으며, 결로가 많이 발생되는 동절기의 온도조건을 기준으로 지하환경의 방수공법별 습도변화량을 분석할 것 이다.

This Research examines the extent of damage on the waterproofing layer in the first floor underground parking lot affected by fire through various waterproofing quality testing. According to the result of the research, although the first floor surface of the substrate layer was damaged due to high temperature of the fire, the waterproofing layer applied in the substrate was not damaged to the point that its waterproofing performance would be affected.

In this study, by blocking the hot warm air inside the sun and is discharged to the outside by checking whether the insulating performance of the insulation and waterproof coating friendly environment using nano-ceramic, and economy through the energy savings it is intended to present a scheme which can minimize environmental pollution and the loss (global warming).

PVC waterproofing sheet is applied in exposed form on the rooftop of building. However, existing reinforcing fiber is would be occurred defect of waterproofing layer tear, because it has a anisotropy. As a result of test, while A-specimen and C-specimen have not the anisotropy, B-specimen has the anisotropy. B-specimen which is applied patterns of reinforcing fiber of I-type, is wide variations in the mechanical properties. C-specimen which is applied patterns of reinforcing fiber of Z-type, is not wide variations in the mechanical properties because it has the anisotropy.

Waterproof layer to the waterproof constructionon the base surface was wet or swelling, problems such as cheered up occurs. In this study, we use the high elastic inorganic coating waterproof material, to evaluate the adhesion of a wet base surface.

This research is an experimental study on the blocking water leakage for micro asystole cement grout(MAC). This study's purpose are confirmed that effective crack repair, mass change, shrinkage and maintenance shape of MAC.

In this study, crack and movement preventing characteristics by waterproofing methods using PE woven fabrics of the punched mesh type was examined. As a result, It can be effectively operating as buffer zone in case of making cracks on the concrete s

Existing polyurethane occurred the environmental issues with the volatile organic solvent mixing tar. This study evaluates the basic properties of a rapid hardening polyurethane, available with spray construction, modified with polyamine mixing carbon black. As a result, stable basic property is measured even surpassed KS.

This study examines preventive technology that is to control the leak by rebuilding the waterproofing layer using adhesive gel for the damaged area expected to raise any disaster if there are making leakage in an underground structure.
