Abstract

An experimental study was carried out to investigate the applicability of cement-based materials for green soil which is a soil for promoting plant growth. The results show that the shear strength of the green soil mixed with gypsum cement (No.3) was low, but the hardness (23.6mm) and pH value (7.4) was most suitable for the vegetation environment. In addition, the initial vegetation germination of green soil, which improved performance by adding a moisturizer, was slower than that of general green soil, and the conductivity value tended to be slightly higher. On the other hand, the slope adhesion of advanced green soil was high, and it was found that the plant growth rate and the regeneration capacity were superior after time passed.

이 연구에서는 사면과의 부착력과 식물 생장력이 높은 식생기반재를 개발하고자, 시멘트 기반의 결합재와 기능성 첨가제를 혼합한 녹생토의 기초물성과 식물 생장에 미치는 영향을 평가하였다. 석고계 시멘트를 혼합한 녹생토(No.3)의 전단강도가 낮게 나타났으나, 식생 환경에 가장 적합한 경도 수준(23.6mm) 및 pH 값(7.4)을 나타냈다. 또한, 보습제를 첨가하여 성능을 개선한 녹생토의 초기 식생 발현은 일반 녹생토 비해 늦고 전도도값은 다소 높은 경향을 나타냈다. 반면, 성능을 개선한 녹생토는 타설면과의 부착력이 높았으며, 일정 시간 경과 후의 식물 생장 속도 및 동절기와 환절기 재생능력이 우월한 것으로 나타났다.
