Concrete Corrosion Pictures?

Concrete Corrosion Pictures?

(OP)
Hi,

Does anyone have pictures (or know of a resource that might have) of buried concrete structures, e.g. pipes, ductbanks, slab-on-grade, foundation, etc., that were corroded due to chloride-and/or-sulfate-containing ground water?  

Cheers!

Maybe Bureau of Mines - maybe Oregon facility

Prestressed Steel Cylinder Concrete Pipe Corrosion Failure
Prestressed Concrete Pipe can suffer accelerated corrosion where either the cement mortar cover is damaged, the pipe is in contact with chloride contaminated or low pH soils or is influenced by stray DC currents. This form of corrosion can result in sudden, bursting failure of the pipe.
   
 SRC Bridge Deck Corrosion
Steel Reinforced Concrete (SRC) Bridge Deck Corrosion is all to common in the United States. Unfortunately, many of the repair and restoration procedures presently in use will not be effective in the long term. The problem is, primarily, caused by use of Sodium Chloride as a de-icing agent, the use of Calcium Chloride as a cure accelerator or by air borne and splash zone sea water contamination of the SRC.
