I live in TN. I have gotten it at a local hardware store, lumber yard, as well as Lowes.
Just ask for cement, or portland cement. Just tell them cement, and NOT concrete mix.

I am jumping into this conversation midstream but thought I would offer a comment. Portland cement is the stuff you can get at the hardware store. It comes in 92 lb bags and smaller ones that you can actually lift into your car. Don't get the stuff that is already mixed with gravel. It is cheaper but will not work. You don't want gravel in you papercrete.
I got into looking at cob oven videos on youtube. There are a slew of them there, some detailed enough to use as directions. Kiko Denzer uses cob as the first course that would come in contact with the fire then puts in a layer of pumice (papercrete would work) and then covers the whole thing with cob. I want to do one of these too so keep us posted on how yours is coming along.

Cob ovens are made from cob. If you make it from papercrete then it will be a papercrete oven.
Is that a good idea? Maybe, maybe not. I have read about someone using papercrete blocks to line a fire pit, and they said it worked fine. I don't remember any followup posts about how long it worked fine, though.
With the right amount of portland cement then papercrete is self extinguishing and just glows from the heat. Since cob ovens often have a firebox underneath then a papercrete oven might work fine if the firebox is lined with something else. It might even work fine if the entire thing is papercrete and you use a cement heavy mix, even a mix with a good amount of clay. Isn't one of the features of cob ovens that they retain heat for hours after removing the fire? That is from thermal mass in the cob. Most papercrete does not have much mass, acting more as an insulator. A massive stone or concrete floor might give enough mass.
I have plans for a papercrete solar oven on the back burner, and way back a desire for a horno. If your papercrete oven works out, be sure to let us know. I have more access to paper than I do to clay.
