The
assessment of the extent of ongoing corrosion damage is a critical step
in the assessment of structures. The amount and extent of ongoing corrosion
is a critical parameter in the selection of means and methods for repairs.
To evaluate corrosion, WDP engineers have a variety of electro- chemical
test methods available. The methods utilized by WDP engineers include:
-
Copper - Copper
Sulfate Half Cells (ASTM C 876)
-
Linear Polarization
Device
-
Concrete Resistivity
Equipment
These techniques
allow WDP engineers to make informed judgements about the true nature of
ongoing corrosion problems in structures. These judgements can be then
translated into long-term strategies for structural repairs.
