Abstract

This paper described the strength variation characteristics to evaluate the applicability of a reactive material that can absorb organic pollutants as an underground barrier. The Strength was evaluated by unconfined compression test. The test results showed that the strength of the reactive material according to the absorption of each pollutant was in the order of water > TCE > TPH. However, the strength of the reactive material absorbing TPH was greater than that of the case absorbing TCE, when the composition ratio of polynorbornene was 12% or less. The strength of the reaction material in contact with water continued to decrease as the polynorbornene composition ratio decreased. The strength of the reaction material in contact with TCE and TPH increased as the polynorbornene composition ratio decreased from 30% to 21%, and then decreased. In other words, the optimal composition ratio of the reactive material should be applied considering the strength due to contact with pollutants according to the stress conditions occurring in the ground.

본 연구에서는 유기오염물의 흡수가 가능한 차수재의 반응재료에 대하여 지중 매입 재료로서의 적용성을 평가하기 위해 오염물의 접촉에 의한 강도 특성 변화를 평가하였으며, 강도 평가는 일축압축시험 결과를 이용하였다. 시험 결과, 오염물 종류에 따른 반응재료의 강도는 물 > TCE > TPH의 순서로 확인되었다. 그러나 폴리노보넨의 구성비가 12% 이하에서는 TPH의 강도가 TCE에 비하여 크게 나타났다. 물로 접촉된 반응재료는 폴리노보넨의 구성비가 작을수록 강도가 지속적으로 감소하였지만, TCE 및 TPH와 접촉된 반응재료의 강도는 폴리노보넨의 구성비가 30%에서 21%까지 작아질수록 증가하다가 이후에는 감소하였다. 즉, 지중에서 발생되는 응력 조건에 따라 오염물의 접촉에 의한 강도를 고려하여 반응재료의 최적 구성비가 적용되어야 한다.
