Description
본 발명은 85% 이상의 라돈 차폐율을 갖는 콘크리트 구조물 크랙의 라돈 차폐방법에 관한 것이다.The present invention relates to a radon shielding method for cracks in concrete structures having a radon shielding rate of 85% or more.
라돈은 자연방사능 물질로 지구상 어디에나 존재하는 무색, 무취, 무미의 기체이다. 이러한 라돈은 실내 환경 중 기체로 존재하며, 상당히 안정화된 물질로 반응에 의해 반감기를 감소시키기에는 어려운 물리적 특징을 가지고 있다. Radon is a colorless, odorless and tasteless gas that is present everywhere on Earth as a natural radioactive substance. Radon exists as a gas in the indoor environment, and it is a fairly stabilized material and has physical characteristics that make it difficult to reduce the half-life by reaction.
세계보건기구(WHO)는 전 세계 폐암발생의 3~14%가 라돈에 기인하는 것으로 평가했으며, 폐암 발병 주요 원인 물질로 규정하고 있다. 특히 미국환경청(U.S. EPA) 자료에 의하면 흡연 다음으로 폐암의 유발요인으로 알려져 있다. 라돈에 대한 주요 국가별 규제동향을 보면, 미국은 4,000 pCi/L(가이드라인), 핀란드는 8,100 pCi/L(먹는물 기준), 노르웨이는 13,500 pCi/L(가이드라인) 등이다. The World Health Organization (WHO) has estimated that 3 to 14% of lung cancer cases worldwide are due to radon, and it is defined as a major cause of lung cancer. In particular, according to data from the U.S. EPA, it is known as the second leading cause of lung cancer after smoking. If you look at the regulatory trends for radon by country, it is 4,000 pCi/L (guideline) in the United States, 8,100 pCi/L (in drinking water) in Finland, and 13,500 pCi/L (guideline) in Norway.
그러나 아파트 고층에서도 라돈이 기준치 이상 검출되는 사례가 매체를 통해 보도되면서, 라돈이 방출되는 건축자재(석고보드, 시멘트벽돌) 및 이의 골재를 사용하는 콘크리트 구조물, 도로포장재에 대한 조사가 실시되었다. 환경부와 국립환경과학원이 전국 7,800여 주택을 대상으로 실시한 전국 주택 라돈 조사 결과, 조사대상 주택 전체의 22.2%가 라돈에 관한 환경부의 다중이용시설 권고기준인 148 Bq/m3을 초과한 것으로 확인되었다. 이에 심각성을 깨닫고 라돈 저감화 기술에 대한 연구가 진행되고 있다. However, as cases in which radon was detected above the standard even in high-rise apartment buildings were reported through the media, investigations were conducted on building materials (gypsum boards, cement bricks) emitting radon, concrete structures using aggregates, and road pavement materials. As a result of a nationwide housing radon survey conducted by the Ministry of Environment and the National Institute of Environmental Research on 7,800 houses nationwide, it was confirmed that 22.2% of the surveyed houses exceeded 148 Bq/m 3 , the recommended standard for multi-use facilities by the Ministry of Environment. . Realizing the seriousness of this, research on radon reduction technology is underway.
현재 국내에서 사용하고 있는 라돈 저감기술은 라돈을 방출하기 위한 환기시스템과 관련된 기술이 대다수이다. 그러나 라돈은 토양으로부터 건물의 균열, 틈새를 통해 유입되기 때문에, 상기 환기시스템을 통한 라돈 저감에는 한계가 있다는 문제가 있다. Currently, most of the radon reduction technologies used in Korea are related to the ventilation system for emitting radon. However, since radon is introduced from the soil through cracks and crevices of buildings, there is a problem in that there is a limit to radon reduction through the ventilation system.
또한, 근본적으로 건물의 균열 및 틈새를 막아 라돈을 저감하는 기술이 연구 개발 중이나 그 효율이 낮다는 문제점이 있다. 예를 들어. 콘크리트 벽면 및 건자재에 바르는 마감재를 통한 라돈 차폐율은 30%를 넘지 않으며, 라돈 저감을 위한 백색도료를 사용하더라도 라돈 저감율은 50%밖에 되지 않는다. In addition, there is a problem that a technology to reduce radon by fundamentally blocking cracks and crevices in a building is under research and development, but its efficiency is low. For example. The radon shielding rate through the finishing materials applied to the concrete wall and construction materials does not exceed 30%, and even if white paint is used to reduce radon, the radon reduction rate is only 50%.
따라서, 본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로서, 본 발명의 해결하고자 하는 과제는 85% 이상의 라돈 차폐율을 갖는 콘크리트 구조물 크랙의 라돈 차폐방법을 제공하는 것이다. Accordingly, the present invention has been devised to solve the above problems, and an object of the present invention is to provide a radon shielding method for cracks in concrete structures having a radon shielding rate of 85% or more.
또한, 본 발명의 해결하고자 하는 과제는 장기간 사용에 대한 내구성 및 크랙 내부에 충진되는 물질의 유동성 등을 개선할 수 있는 콘크리트 구조물 크랙의 라돈 차폐방법을 제공하는 것이다. In addition, an object to be solved by the present invention is to provide a radon shielding method for cracks in concrete structures that can improve durability for long-term use and fluidity of materials filled in cracks.
또한, 본 발명의 해결하고자 하는 과제는 크랙 내부에 충진되는 접착제 성분의 안정성을 향상시킬 수 있는 콘크리트 구조물 크랙의 라돈 차폐방법을 제공하는 것이다. In addition, an object of the present invention is to provide a radon shielding method for cracks in concrete structures that can improve the stability of the adhesive component filled inside the cracks.

본 발명에 따른 콘크리트 구조물의 라돈 차폐방법을 각 단계별로 구체적으로 살펴보면 다음과 같다. The radon shielding method of a concrete structure according to the present invention will be described in detail for each step as follows.
먼저, 1단계는 콘크리트 구조물에 발생된 크랙 부분에 알루미늄 입자가 함유된 발포성 접착제를 충진한다. First, in the first step, a foamable adhesive containing aluminum particles is filled in the cracks generated in the concrete structure.
상기 알루미늄 입자가 함유된 발포성 접착제는 폴리에스테르 열가소성 수지, 발포제인 및 알루미늄 입자를 함유한다. The foamable adhesive containing aluminum particles contains a polyester thermoplastic resin, a foaming agent, and aluminum particles.
폴리에스테르 열가소성 수지는 당 분야에서 일반적으로 사용되는 것으로, 수평균분자량이 26,000인 것이 바람직하다. 일례로 아크릴로니트릴, 메타크릴로니트릴, α-클로르아크릴로니트릴, α-에톡시아크릴로니트릴, 푸마로니트릴 공중합체 또는 이들의 임의의 혼합물 등을 들 수 있다. 바람직하게는 아크릴로니트릴 또는 메타크릴로니트릴 공중합체일 수 있다. The polyester thermoplastic resin is generally used in the art, and it is preferable that the number average molecular weight is 26,000. Examples include acrylonitrile, methacrylonitrile, α-chloracrylonitrile, α-ethoxyacrylonitrile, fumaronitrile copolymer or any mixture thereof. Preferably, it may be an acrylonitrile or methacrylonitrile copolymer.
발포제는 OBSH(P,P'-Oxy bis(benzene sulfonyl hydrazide) 및 TSH(P-Toluene sulfonyl hydrazide)을 혼합사용하며, 이때 혼합비는 1:1중량비인 것이 바람직하다. 상기 발포제는 폴리에스테르 열가소성 수지 100 중량부에 대하여 6 내지 10 중량부 함유한다. The blowing agent uses a mixture of OBSH (P,P'-Oxy bis (benzene sulfonyl hydrazide) and TSH (P-Toluene sulfonyl hydrazide)), and the mixing ratio is preferably 1:1 by weight. The blowing agent is polyester thermoplastic resin 100 It contains 6 to 10 parts by weight based on parts by weight.
알루미늄 입자는 표면적이 클수록 요변성(thixotrophy) 부여 효과가 크기 때문에 입경이 5 내지 200 nm, 바람직하게는 5 내지 40 nm인 것이 좋다. 상기 알루미늄 입자는 폴리에스테르 열가소성 수지 100 중량부에 대하여 3 내지 6 중량부 함유하며, 상기 함량이 3 중량부 미만이면 그 양이 미미하여 라돈 차폐 성능이 저하될 수 있고, 6 중량부를 초과하는 경우에는 발포성능이 저하될 수 있다. The larger the surface area of the aluminum particles, the greater the thixotrophy imparting effect. Therefore, it is preferable that the aluminum particles have a particle diameter of 5 to 200 nm, preferably 5 to 40 nm. The aluminum particles contain 3 to 6 parts by weight based on 100 parts by weight of the polyester thermoplastic resin, and if the content is less than 3 parts by weight, the amount is insignificant and the radon shielding performance may be reduced, and when it exceeds 6 parts by weight, foaming Performance may be degraded.
이러한 상기 알루미늄 입자가 함유된 발포성 접착제는 총 크랙 발생 부분에 50 내지 80 부피% 범위로 충진되며, 상기 충진량이 50 부피% 미만이면 크랙 부분에 공간이 발생할 수 있으며, 80 부피%를 초과하는 경우에는 이후에 충진될 콘크리트 접착제의 양이 상대적으로 감소하여 보수된 크랙의 내구성이 저하될 수 있다. The foamable adhesive containing the aluminum particles is filled in the range of 50 to 80% by volume in the total crack occurrence portion, and if the filling amount is less than 50% by volume, a space may occur in the cracked portion, and when it exceeds 80% by volume The amount of concrete adhesive to be filled thereafter is relatively reduced, and thus the durability of the repaired crack may be deteriorated.
또한, 본 발명은 상기 발포성 접착제를 충진한 후, 이후의 콘크리트 접착제를 충진하기 전에, -10 내지 40℃ 정도에서도 신장율과 인장강도를 향상시켜 콘크리트의 내후성을 강화하기 위한 강화제 조성물을 추가로 충진할 수 있다. 상기 강화제 조성물은 아크릴 에멀젼 45 내지 50 중량%, 칼슘카보네이트 20 내지 30 중량%, 폴리우레탄 5 내지 10 중량%, 이산화티타늄 1 내지 5 중량%, 에틸렌글리콜 0.5 내지 1 중량% 및 잔부 수분으로 구성될 수 있다. In addition, the present invention is to improve the elongation and tensile strength even at about -10 to 40 ℃ after filling the foamable adhesive, before filling the concrete adhesive after filling, a reinforcing agent composition for strengthening the weather resistance of concrete. can The reinforcing agent composition may be composed of 45 to 50% by weight of an acrylic emulsion, 20 to 30% by weight of calcium carbonate, 5 to 10% by weight of polyurethane, 1 to 5% by weight of titanium dioxide, 0.5 to 1% by weight of ethylene glycol, and the remaining moisture. have.
다음으로, 2단계는 상기 1단계 알루미늄 입자가 함유된 발포성 접착제가 충진된 크랙에 경화제 및 알루미늄 입자가 함유된 콘크리트 접착제를 충진한다. Next, in the second step, the concrete adhesive containing the curing agent and the aluminum particles is filled in the cracks filled with the foamable adhesive containing the aluminum particles of the first step.
