Abstract

The cemented sand and gravel (CSG) method is a construction technique that adds cement and water to rock-like materials, such as rivered gravel or excavation muck which that can be obtained easily at areas adjacent to dam sites. This study was performed to evaluate the planting properties of herbaceous plant and cool-season grass in CSG blocks that were manufactured by using CSG materials to develop environmentally friendly CSG method. The two types of CSG-0 without cement and CSG-100 with $100\;kg/m^3$ of cement were designed to evaluate compaction, unconfined compressive strength and growth of plants with cement content by using modified E compaction. To analyze growth properties of plants, germination ratio, visual cover, plant height and root length were measured in 4 weeks and 8 weeks after sowing. As the results, the germination regardless kinds of plants started within 5~7days and the germination ratio were in the range of 50~60 %. The visual cover of kinds of plants by visual rating system were in the range of 7~8 and the visual cover of tall fescue and perennial ryegrass was higher than that of lespedeza cuneata. The plant height and root length for tall fescue and perennial ryegrass in 8 weeks after sowing were in the range of 22~26 cm, 12~15 cm and 4~6 cm, 3~5 cm, respectively.
