Abstract

Recently, Both rapid economic growth and high-quality native finishing materials demand in buildings such as local infrastructure facilities and cultural facilities have increased along with local quarries. So, increasing local quarries and environmental pollution occurred in quarries get the eyes to damaged area of the surroundings. As an example, carcinogen such as solid formed to fixing asbestos and dust have damaged to local resident. Especially, Radon gas released from asbestos can exist everywhere on earth, released soil and rock as radioactive substances, can be caused lung cancer followed by a smoking. When pollution source to indoor air quality that lacking ventilation rate of the residential building moved in a cycle, human responses such as headache, dizziness, etc. get appear, so on it threatened resident's physical condition. Thus, we need to urgent attention to reduction harmful substance. In the case of radon gas of the pollution source to indoor air quality in housing, it has characteristic that keep on going through half-life released from source, we need to control radon gas source than source removal. We set on vermiculite addition ratio to 10% which has harmful substances adsorption performance, proceed experiment to basalt waste rock addition ratio 50, 60, 70, 80(%). The result of an experiment, based on 'KS F 4035, precast terrazzo', we can be obtainable in the best terrazzo at basalt waste rock addition ratio 70%.

최근 급속한 경제 성장과 함께 국내 산업기반 시설과 국민생활기반 시설과 같은 국내 건축물 고급화로 천연석재 마감재 수요 증가와 동시에 국내 채석장 수도 증가하고 있다. 이에 따라 채석장의 증가와 함께 채석장에서 발생하는 환경오염으로 주변 지역 피해가 주목받고 있다. 예를 들자면, 채석장으로부터 흘러나온 석면이나 분진이 응집되어 생기는 고체와 같은 발암물질로부터 지역 주민들은 위협받고 있다. 특히 석면에서 방출되는 라돈가스는 지구상 어디에나 존재하고 토양과 암석에서 방출되는 자연방사능 물질로 흡연에 이어 폐암 발병의 주요 원인이다. 실내 환기량이 부족한 상태에서 실내공기 오염원이 지속적으로 순환될 경우, 두통, 현기증 등의 인체반응이 나타나면서 거주자의 건강을 위협하기 때문에 유해물질 저감이 시급한 실정이다. 주택 실내공기질의 오염원 중 하나인 라돈가스의 경우 방출원에서 반감기를 거쳐 계속해서 방출되는 특성을 가지고 있으므로 완벽한 제거보다 방출원에 대한 제어가 필요하다. 라돈가스와 같은 유해물질 흡착 성능을 가진 버미큘라이트의 첨가율을 10%로 고정하고 현무암 폐석을 50, 60, 70, 80% 첨가하여 실험을 진행하였다. 실험의 결과로 'KS F 4035,기성 테라죠'에 의거하여 종합적으로 고려할 때 현무암 폐석의 첨가율 70%에서 최적의 인조석재를 제조할 수 있는 것으로 판명되었다.
