Abstract

This study conducted acute oral toxicity test and acute dermal toxicity test to evaluate the toxicity of lightweight and high-strength cement composite containing carbon nanotube. It was compared with the toxicity of ordinary concrete that did not contain carbon nanotube. Both lightweight and high-strength cement composite and ordinary concrete were categorized in GHS category 5 as a result of acute oral toxicity test. In addition, no toxic symproms were observed during the acute dermal toxicity test in all specimens, concluding that those were judged to correspond to GHS category 5/unclassified.

본 연구에서는 탄소나노튜브를 혼입한 경량·고강도 시멘트 독합체의 유해성을 평가하기 위해 급성경구독성시험 및 급성경피 독성시험을 실시하고, 이를 재령 28일 압축강도 50 MPa 수준의 탄소나노튜브를 혼입하지 않은 일반 콘크리트의 유해성과 비교하였다. 일반 콘크리트 및 탄소나노튜브를 혼입한 경량·고강도 시멘트 복합체 모두 급성경구독성시험결과 GHS category 5인 것으로 조사되었다. 또한, 모든 시편에서 급성경피독성시험에서 독성증상은 관찰되지 않았으며, GHS category 5/미분류(unclassified)에 해당하는 것으로 판단된다.
