摘要：
The cross sectional repair of concrete structures is carried out for the purpose of restoring or improving durability. However, some re-deterioration, such as corrosion of reinforcing bars, floating of repair materials, or peeling, has been observed. Such re-deterioration is considered to be due to deterioration factors such as water that has permeated the repair area. In this paper, we report the result of non-destructive visualization of the moisture behavior of the repair area using a neutron beam tester. © 2022 Ken-yusha Inc.. All rights reserved.
