Corrosion Resistance of Stainless Steels in Soils and in ...

In such aggressive environments, stainless steel piping buried in soils should therefore be coated. In concrete structures with high levels of chlorides in marine environments, stainless steels generally offer an excellent alternative where other metallic materials are subjected to corrosion. 1.

Research on Electrically Conductive Concrete with Double ...

Nevertheless, traditional road salt and deicing chemicals may cause damage to concrete and corrosion of reinforcing steel. To this end, a new type of electrically conductive concrete with doublelayered stainless steel fiber (DSSF) for deicing of pavement is actively developed and tested in this study.

Dowel Bar Placement Pavement Interactive

The FHWA notes “…The dowel must be free to slide in the concrete so that the two pavement slabs move independently, thus preventing excessive pavement stresses. Only a thin coating should be used, as a thick coating may result in large voids in the concrete around the dowels” (FHWA, 1990a [1]). Figure 3 shows dowel bars with excessive ...

Corrosion of Embedded Materials

If metal is to be used as flashing, stainless and galvanized steel are better choices. Stainless steel is one of the least reactive metals, but it can be difficult to cut and bend, and some of the lower grades of stainless might be more reactive than you would think. Copper is a good option too—but it is expensive.
