This study is part of a special research project aiming to identify research and development themes for the Daegyeong Region, in order to discover diverse ideas and challenges with higher potential for success to be considered for regional technology innovation projects. To that end, it analyzed regional characteristics of the Daegyeong Region, investigated technology demands and examined research capabilities and infrastructures in order to identify new research subjects. As a result, the study obtained the following outcomes as research themes for the Daegyeong Region.
□ Vision for R&D involving the Daegyeong Region
○ Use of weathered sedimentary rocks in the Daegyeong Region, the Nakdong River dredge and industrial byproducts as aggregate, and development of alternative aggregate, and development of methods to evaluate stability of batters of sedimentary rocks and reinforcement effect
- Use of weathered sedimentary rocks in the Daegyeong Region, the Nakdong River dredge and industrial byproducts as aggregate, and development of alternative aggregate
• There is a need to enhance the region's construction industry by developing alternative aggregate through the use of sedimentary rocks (shale and mudstone) widely dispersed in the Daegyeong Region as concrete aggregate, by raising construction efficiency and reducing construction costs.
• There is a need to devise a mid- to long-term measure to supply sand in a stable manner as there is a possibility that the supply of river aggregate may be drastically reduced when the Four River project is completed. Moreover, unlike other regions, it is difficult to utilize sea sand in the Daegyeong Region, and the downstream of the Nakdong River has more microsand than the mid- and upstream, causing a lot of problems such as drying shrinkage, flowability and durability when used as concrete aggregate. In order to address such problems and to secure resources for aggregate, research is necessary on ways to increase utilization of the Nakdong River's microsand.
• The Daegyeong Region is home to major industrial clusters including the textile industrial complex in Daegu, the electronic industrial complex of Gumi, the iron casting industrial complex in Goryeong and the steel industrial complex in Pohang. The volume of industrial byproducts such as sludge and waste molding sand produced from these industrial clusters is on the rise each year, which calls for higher recyclability for environmental conservation and efficient treatment.
- Evaluation of the characteristics of sedimentary formations and stability of batters in the Daegyeong Region
• There is a need to develop a design parameter evaluation technique to analyze the characteristics of sedimentary formations in the Daegyeong Region and apply the result to actual design, as well as to evaluate accurate soil constants required for the design.
• Stability of batters of sedimentary formations is closely linked to stratification of the sedimentary formations, and batters in the Daegyeong Region mostly consist of sedimentary formations as well, requiring development of evaluation techniques for batter stability and optimal reinforcement method for construction.
