단열재 활용을 위한 폐EPS(Ingot)의 기본 특성

초록

This research investigated drainage and insulation characteristics of the Ingot which is the part of the EPS wastes for the purpose of frost prevention in the railroad track. Ingot is produced by the baler during the course of the recycling process of the EPS wastes. Thermal conductivities were measured for different rate of gravel-Ingot mixtures to use for the ballast layer of railroad track. From the test result, it can be seen that Ingot is useful material as ballast layer due to its insulation and durability characteristics
