Abstract:
Korea has high density of population, considering the size of the territory. So, the importance of convenient and comfortable apartment buildings and high-rise residential-commercial complex buildings has been rising. In addition, because of the improvement of the standard of living along with continuous national economic growth, the interest in well being and the expectation of quiet life for comfortable and pleasant residential environment have also been increasing. However, Korea has the life style of sitting on the floor, so floor impact sound has been occurring more and more frequently. Because of that, neighbourly disputes have been a serious social problem. And lately damage and disputes from noise between floors have been much more increasing.
This research, therefore, used waste tire chips as a resilient material for reduction of floor impact sound in order to recycle waste tires effectively. And also a compounded resilient material, which combines EPS (Expanded Polystyrene), a flat resilient material of the upper part with waste tire chips of the lower part, was developed. After constructing waste tire chips at a standardized test building, a test for noise reduction of light-weight impact sound and heavy-weight one was performed. The test proved that it was possible to control effectively light-weight impact sound and heavy-weight one, when using waste tire chips as a resilient material for reduction of floor impact noise.
