Another instance of 'Super Ice' or as named in the article 'Pykrete' in science fiction is in Neal Stephenson's Novel from 2015: Seveneves.
The substance is used in space for the construction of temporary habitats.
I suppose this is plausible if you manage to find a large source of ice and bring it into a stable orbit. It won't melt into liquid, and perhaps the reinforcing fibers could help prevent sublimation.
A lot of the novel strained my ability to suspend disbelief, but the overall scope and ambition is so awesome I was able to forgive the poor editing. It's attempting to be hard sci-fi, much of the novel is taken up by technical descriptions that could only appeal to an engineer-minded person.

While the 2nd half of the book is definitely still sci-fi territory, the first part is slowly getting into the plausible tech realm, 12 years after the book was written. We now have a much stronger space industry, and probably could match or exceed the payload to orbit in 2 years from the book (if everyone would work towards the same goal, which is still a bit of fantasy but hey...)
The Wikipedia article mentions how this happened with an anti-AIDS medication called ritonavir. I watched this video by Veritasium on that situation a while back; I recommend it: https://www.youtube.com/watch?v=ksn5yrsC3Wg
"The intended application isn't for aircraft carriers this time, but rather for construction projects in remote, cold areas where conventional building methods aren't easy to apply – like the Arctic and Antarctic.
With no concrete or steel required, and with ice and plant-based cellulose as the main ingredients, this could be a building material with a low carbon footprint that's also biodegradable."
"Further down the line, this approach could open up a whole new landscape for materials used in packaging, construction, and more: Using a custom protein to bring two unlikely compounds (ice and cellulose) together."
I hate how researchers always have to pretend there's a practical application for their inventions. This is clearly never going to replace concrete in any situation. But it's still interesting.
This type of ice composite would be super interesting for space structure construction. Melt cometary ice and mix it with additives of some kind and spin big cylinders out of it. You’d just have to make the surface reflective so it doesn’t melt, and possibly have some active cooling which you need anyway if anything inside makes heat.
The outer surface would probably be sprayed with something, maybe just reflective dust, to also keep it from subliming into the vacuum.
Extremely repairable, melts at human and equipment friendly temperatures, recyclable, doubles as an emergency water reservoir, and last but definitely not least a fantastic radiation shield.
Would also work for structures on Mars, the Moon, etc, but I’m a fan of the idea of settling space itself not another planet. Gravity wells are a trap.
The article briefly touches on future packaging. Would ice ever be useful in packaging frozen foods? It'd be biodegradable, and would be a sign of trust that the goods have been permanently frozen from packaging to delivery.
You'd literally be able to just throw the trash outside and let it feed your garden, lol.
The integrity check could also make this especially valuable for transporting medication that must remain cold. The current state of the art isn't much more than putting ice packs in a styrofoam cooler.
