Steel Corrosion in Concrete- References and Books

[MJB315]

All,

I would like to become better aquainted with corrosion-related issues in reinforced concrete structures. Investigation strategies and techniques, as well as remedial repair products and methods.

Can anyone suggest a book(s) or references that they have found useful? Note: I have the current ACI Manual of Standard Practice references, but I would still welcome suggestions within it (perhaps certain chapters / excerpts) that folks have found useful.

Thanks,
MJB

I think the best publication is the 2 volume concrete repair manual set from ICRI. I like the fact that it is a worldwide compilation of technical documents.

http://www.icri.org/bookstore/bkstr.asp

combine this with
Concrete Repair and Maintenance Illustrated: Problem Analysis; Repair Strategy; Techniques (RSMeans) (Paperback)
Peter H. Emmons

Also order the Sika concrete repair products catalog and literature set.

Free manual:

U.S. Army Corps of Engineers EM 1110-2-2002, Evaluation and Repair of Concrete Structures.

They have several books available for download on this subject.

ICRI is the authority on repair. We also have some information on the crsi.org website. Under the "Engineering" tab on the top navigation bar, pick "Durability" as a starting point.

Thanks- I have been getting into the reading and I appreciate the suggestions.

Separate but related issue: I had heard that many widely used proprietary concrete repair mixes (used for bonded overlays / patches of deteriorated concrete) are mixed with chlorides (potassium chloride) to assist with shrinkage and durability. Manufacturers are allowed to use amounts (~<1% by weight) of chlorides in their products and not have to inform the engineer / user.

I heard that by using materials with chlorides in them, any galvanic cells present in the structure can restart (or be made worse) after the repair is complete. (Bars within the patch material are often produced by coating them with a separate protective primer). The end result is the repaired patch itself performs very well, but the surrounding concrete is harmed.

Does anyone have any information / war stories regarding using proprietary bag mixes and their effects on existing structures?
