Not to mention the average normal size of an opening you’d have to plug to begin with. Even if it didn’t just drain down the hole or dissolve the moment it got to lava, it would be a ludicrous amount of concrete just to make a layer a few feet thick. Even if you did manage to make a plug a hundred or more feet deep and it didn’t melt or move, an eruption would likely just blow the mountain apart from around it.
All you’d need is ultra fast drying lava-proof concrete. I’m surprised no one has thought of that yet. Then once the crater vent is fully plugged you would just need to coat the rest of the mountain in the same concrete. Voila, problem solved.

I keep thinking about the big job we have ahead of us, paving over Yellowstone Park.
Don’t give them any ideas
If it’s concrete i think it will just explode upon contact because of the water content.
Yeah, that “even if” of mine was doing some heavy lifting.
I want to see it done just to see how far the concrete cap goes flying when it finally pops off.
