| 摘要 |
The invention relates to a device and method for determining chloride migration coefficients, comprising a first ionic conducting gel having an NaCl matrix (2, 22), in which: the first ionic conducting gel is in contact with a concrete test piece (3, 23) and is connected via an electrode (1, 21) to the negative pole of a power supply; and the electrical circuit is closed with a second ionic conducting gel having an NaNO 3 matrix (4, 24) connected via a second electrode (1, 21) to the positive pole of the power supply. A similar arrangement, in which the ion in the matrix is replaced with other types of ions, allows the introduction of species and facilitates the movement thereof through the concrete for other purposes, such as, for example, the incorporation of cationic inhibitors. |
