Class F vs class C flyash
(OP)
Which one is the more common type of flyash for general residential and smaller commercial projects (sog, foundation wall, basement wall etc)? When to use one class vs the other?
Thanks.
Thanks.

I think Class F combines more completely with the other cementatious materials.
Ask your local batch plants what they use.

It is a local situation and depends on availability and freight costs.

On large projects, where new mixes are critical to function, the development and testing costs are worth while. Not so much on small projects.

Jed, yeah I heard somewhere that east of Mississippi is class C and west is class F.
I'll contact 2 or 3 major suppliers in the area to get a more definite answer.
