Concrete - Soil Sulfate

Concrete - Soil Sulfate

Concrete - Soil Sulfate

(OP)
I have a soil's report, whichs says "the soils onsite were found to have moderate to severe corrosive potential to concrete and metal...".  "...The report recommends Type II with fly ash or Type V portland cement or equivalent..."  Would I specify the concrete strength of 4,000-psi for Type II and 4,500-psi for Type V per ACI Table 4.3.1?  Is there a concrete mixture for the above condition for concrete strength of 2,500-psi.

RE: Concrete - Soil Sulfate

You're referencing ACI 318, which is the Concrete Building Code.  To be conservative, use a 4500 psi mix with Type V cement.  If you're constructing something that is not under the auspices of a building code (sidewalk?, conduit encasement?) you might get away with a 2500 psi mix.  But there's no 2500 psi mix that meets ACI 318.
