The following research has taken place from the buildings' that has been there between 20-40 years, located near the coastal areas and its level of flying salinity and effect elements are classified into its standard level, distance/range level, material level, direction level, region level, floor level and actual distribution of salinity content has been found. The buildings that are situated within 600m of the coastal area, which are ready to be demolished in Busan City, Nam-Gu, Su-young and Hae-woon-dae, such as apartments, hotels and long-term aged has been selected for the core test. From these selected buildings the core testing samples were drawn, an abscission took place in the interval of 10mm to 50mm depth from the surface and the following has been found from the each salt content level. From the selected 51 core test samples, the salinity level has been analysed and its result indicated that 14 samples (27%) fits under the regulated standard level of salt content of 0.3㎏/㎥ for the iron concrete, 8 samples (16%) leveled from 0.3∼0.6㎏/㎥, and the remaining 29 samples (57%) indicated fairly high level of 0.6∼5.5 ㎏/㎥ in salinity content level. And the salt content level from 20∼200m distance was at an average of 1.63㎏/㎥, and at 200∼600m distance showed 0.46㎏/㎥ salt content level, which indicates an obvious difference. The most suitable finishing material could be exposed concrete material and exposed finishing which indicated almost 2.0㎏/㎥ difference.
