Sulfuric Acid & Steel & Concrete

Sulfuric Acid & Steel & Concrete

Sulfuric Acid & Steel & Concrete

(OP)
I am currently working on an industrial project in which there are vats of diluted sulfuric acid (such as for a galvanizing plant).  In general, none of this acid will ever reach that slab-on-grade, but there will be instances in which I am sure it will spill occasionally.   Also, the vapors being emitted will rise to the ceiling.  

The thought is that this will be a precast structure with steel hangers for the hoist beams.  Is there any special admixtures I can add to the concrete to help deter the effects on the concrete?   Also, is galvanizing the steel a waste of the owner's money, since galvanizing just disolves by the acid anyway?   Is there another substance that can be applied to the steel?

I was hoping someone else may have some sort of experience with this type of application.   

RE: Sulfuric Acid & Steel & Concrete

Epoxy coating.  Proper selection for both the concrete and the steel will go a long way toward protection from sulfuric acid.

RE: Sulfuric Acid & Steel & Concrete

Keep w/c ratio very low and perhaps add silica fume to the concrete.  

RE: Sulfuric Acid & Steel & Concrete

In vessel work, it is generally the assumption that the owner, based on past experience, will specify any special provisions to deal with whatever specialty chemicals or special conditions are involved.  I would suggest applying this approach to the case at hand.
