The study was intended to identify the absorption of flying salinity and internal distribution into the concrete of the buildings aged 20 to 40 years in a coastal district through the tests. The buildings subject to sampling for the test includes apartment and hotel buildings located within 500m from the seashore in the area of Nam-Gu, Suyeong-Gu and Haeundae-Gu in Busan. Those old buildings were mostly planned to be rebuilt or demolished. The core specimens were taken from the buildings, and were cut into 10㎜ and 50㎜ in depth and soluble salinity contained in concrete specimen were measured.
The results are follows.
(1) An average content of salinity contained in the specimen taken at the survey area was minimum 0.09㎏/㎥ and maximum 5.55㎏/㎥, which had a wide range of distribution. Viewing the content by specimen, the specimen at 10㎜ depth taken from the P-building contained as much as 13.17㎏/㎥, indicating the highest level among the specimens.
(2) Among 51 specimens, 14(27%) were within the allowance of 0.3㎏/㎥ and 8(16%) were in 0.3㎏/㎥～0.6㎏/㎥, while remaining 29(57%) were in the range of 0.6㎏/㎥～5.5㎏/㎥, which was regarded a high level of salinity content.
(3) The content of salinity was found to be dependent on distance from the seaside, age and coating type of building, and the content of salinity has been increasingly growing as long as the building exists.
(4) In comparing the ratio of salinity distribution
