I use tire slime. Its common in usa in automotive stores. With no air in tire, you hand pump or pour the slime into the tire valve (after removing the valve itself). Then air it up and use it. I think it hardens when exposed to air so it will flow into a leak then seal it.
What i don't like about your suggestion is how to know the tire is full. What if it is 3/4 full of the aircrete, leaving 1/4 as a big air bubble. How does air get from the valve, through the aircrete, to where its needed,? It seems like the chance to totally ruin the whole tire is high. I envision a big flat spot in the tire that is worse than just being low on air. I also don't know that it would have more compression strength than foam.
I have had forklift tires foam filled. It was done professionally. Over time i had exposed foam from pieces of tire coming off. It never crushed. Cost is not feasible for a wheelbarrow, but for commercial machinery it is viable.

Okay, this is totally off-topic but for the sake of curiosity, how did he join the ends and not have a bump at the connection?

Not so off-topic if you attempt to use recycled rubber from car tires.
Here's an account I ran across while researching home made sandals:
"...He punched discs out of tires to make bicycle tires (for those who were lucky enough to still have a bike.) You bought enough of the discs, drilled or burned holes in the center, and ran a sturdy fence wire through the holes. To mount these 'tires' one twisted the fence wire until it was tight enough take up any slack. It was a very hard ride, especially on the old cobblestone roads, but it was better than walking for some people."
