Abstract

친환경 지반개량공법인 EICP 처리를 통해 실내 및 현장 실험을 실시하여 미세먼지 억제 효율을 평가하였다. 실내 실험에서는 현장 적용성을 고려하여 저렴한 물질로 EICP 용액을 제작하였으며, EICP 용액의 최적 혼합비 및 처리량을 산정하였다. 용액의 최적 혼합비는 요소/염화칼슘의 비율이 1.5 및 백태가루 15g/L일 경우, 최적의 탄산칼슘 생성량을 보였다. EICP 용액 최적 처리량은 7L/m2이며, 미세먼지 억제 실험 및 콘팁저항치 측정 실험을 통해 결정되었다. 현장 실험은 덤프트럭이 통행하는 test-bed에서 살수 실험 및 EICP 실험을 각각 실시하였으며, 현장의 상황에 따라 효율적인 미세먼지 억제법은 달라질 것으로 판단된다.

The efficiency of suppressing fine dust was evaluated by conducting indoor and field experiments for the ground treated with EICP solution, which is an eco-friendly ground improvement method. In laboratory experiments, the EICP solution was prepared with inexpensive materials for the field applicability, and the optimal mixing ratio and optimal spraying volume of EICP solution were calculated. The optimum amount of calcium carbonate was shown when the ratio of urea/calcium chloride and white powder were 1.5 and 15 g/L, respectively. The optimum spraying amount of the EICP solution was 7 L/m2 determined by fine dust suppression and cone tip resistance experiments. The spraying of water and EICP solution was conducted at the test-bed where dump trucks pass for the effect of suppressing fine dust of each method. The effective fine dust suppression method can be chosen depending on the situation of the site.
