Re: Reducing required cover of non-prestressed c.i.p. concrete

If anything it strengthens it, as it is towards the tension face.

Does the displacement of the reinforcing impair the strength of the wall to resist soil pressure?

I have an 8" concrete wall that includes a section with reinforcing that has encroached to within 3/4" of the form.  Parts of this area are covered with 8" of stone veneer (exposed to wheather), and part is to be covered with earth (sealed with drainboard applied).  The concrete included the Zypex (sp?) additive.
 
My questions are:
 
Will the protection provided by the veneer allow a reduction in cover?
 
Will the additive allow a reduction in cover due to extra protection?
 
Thanks for any comments.
