Ten years ago I sprayed and hand packed papercrete for my big dome in February and March, with icicles hanging off the tow mixer at times. I never noticed any difference with that papercrete vs stuff done in warmer weather. This year I experimented with cellulose insulation (posted a link to a video) in conditions like you have and in the morning the wet pc was frozen hard at least on the surface. No problems, it thawed, dried, and looks like papercrete.
An extended freeze might possibly be a problem but I think the pc would just eventually thaw and cure like my partially frozen panels.

...Well... my project is running late this fall and we are now into the season of freezing nights. Not every night yet, but some nights. Soon, every night. And, I still need to make a bunch of large forms. If I pour early in the day and daytime temps are in the 40s to 60s, but nighttime temps dip below freezing -- into the 20s -- will my forms cure OK? Or will they crack as they expand and contract in the freeze-thaw cycles. Anyone have experience with this? (Actually, bet it's been discussed here many times before. Didn't search.) I guess the added cure time would vary depending upon how long it takes to thaw each day and how much drying time it gets before it refreezes. Obviously it will take longer to cure -- if it will cure satisfactoriy at all. Would really appreciate input on this before I potentially waste a lot of time and effort if experience has proven it's not going to work out.
