Concrete Protection In A Storage Building

Concrete Protection In A Storage Building

Concrete Protection In A Storage Building

(OP)
Can anyone recommend any special precautions to be taken for the concrete floor and walls in a storage building. The main storage material will be Nitrate based fertilizers. I intend to use horizontally spanning precast concrete wall panels between steel columns for the retention of the fertilizer up to a retained height of 6.0m.
The floor slab is to be in-situ concrete slab on grade.
Are any special additives etc required in the concrete

Ok...I'll take a shot at this one. Consider either a specialty coating, maybe a 2-part epoxy, and/or a concrete additive. We have used Sika products for many years in industrial settings (electric generating stations) to successfully protect concrete from chemical attack. The chemical attack here is from sulphur-based compounds but the chemistry for nitrogen-based compounds is probably similar.
Take a look at www.sikaconstruction.com
You may want to contact Sika to discuss your situation & get a specific product recommendation, I have found their technical staff to be both knowledgeable & helpful.

A couple of additional thoughts:

1.  Contact Master Builders, Sonoborn and W. R. Meadows, they all make a variety of concrete coatings for various enviorments.

2.  A few years ago I was involved in the construction of a chemical storage facility.  The majority of the products were fertilizers.  In that instance, the only floor coating was a cure & seal coating to keep down the dust.  However, the materials stored were all in some type of manufacturer's packaging: barrels, bags etc., no chemicals were stored directly in contact with the concrete.  It sounds like your in a situation where the fertilizer will be stored in bulk, on the concrete floor.

This response may be a little too late.  We have found that an additive called Correchem improves concretes resistance to nitrate attack. It is marketed in the US by Norchem (www.norchem.com). If you want additional information, just ask.
