볏짚재를 활용한 식생콘크리트 블록 개발 및 사면 적용성에 관한 실험적 연구

Abstract

This study was performed to develop the plantable concrete block using rice straw ash and apply for inclined plane. For the planting, plantable concrete block needs infiltration of water and air through void of block. The materials used for plantable concrete block are cement, rice straw ash, and coarse aggregate (5-10, 10-20 mm). Plantable block size is 23×23×4 cm, and species of planting are Tall fescue, Lespedeza cyrtobotrya and Lespedeza cuneata.At the 6 months after seeding, germination ratio and grown-up length of Tall fescue, Lespedeza cyrtobotrya and Lespedeza cuneata are shown in 90%, 60%, 50%, and 40∼50 cm, 90∼120 cm, 60∼75 cm, respectively.
