Pykrete is one of those things that makes sense in theory, but in practice and from a practical perspective just isn't great.
There aren't a lot of places in nature where you have tons of trees and easy to get ice. So a society would never default to pykrete because those two things tend to be the opposite of each other. Its a somewhat unnatural thing to do.
Industrialized societies just can make steel and steel doesnt start to soften until 500-600 degrees F. There's no need for a 24/7 refrigerator power plant to keep steel from melting. Steel also is strong and rigid. Steel is of course still used today for both war and civil ships, and has been since the day it became technically and economically feasible to do. Its really hard to beat steel. This project has some nice technical merits and pykrete itself is interesting, but it just doesnt seem to ever have a practical use.

I take issue with this - there are vast swathes of canada, sibera, and northern europe where this is the case. I would say however finding all three year-round near liquid water may be harder, although not exactly an insurmountable challenge compared to say, moving quarried rock 5 miles to build a house
