I was thinking along the lines of an actual liquid or contaminant that, once laid down, hardens into a solid natural wall over time, which would be the non-trivial thing to mod in. I presume one might have it as a workshop activity to combine a bucket of water and a bag of cement to make liquid cement. Also a timer that requires its use by a certain time might be a nice little touch. The reaction itself is trivial to mod in to make concrete bricks, but thats not what i'm thinking.
That's actually really interesting. Concrete a
'heavy contaminant' drops to the bottom of some water and solidifies the whole way up in stages (because surface would be fiddly in having to remove in stages, sucking the water up and making a bell which though alternatively might be more fun from a engineering point), and by constructive walling and dropping of the concrete you can form a pier or just a pillar of concrete 'rock' in say the middle of the sea or a aquifer (with a LOT of expensive flux reliant concrete which will hitch the price up)

I guess dwarves wouldn't care about such a trivial thing as weak concrete and dump the whole lot in by quantity into the water to solve a problem, OR via just the game world having slightly altered values compared to the real world, having a more porous form of concrete that just doesn't care and remains strong in water regardless because of the special qualities of DF world flux and clay.

would also have some use in a simpler way to "fill holes" by making a pond the dwarfs can fill with cement.
I got ninja'd but yeah.
I wonder if the concrete would need to be made into stone first if you were making a edifice out of concrete blocks (lets say a built fortification for your concrete bunker you've hollowed out) to build features such as bridges/fortifications/embellishents like statues or if it would need to be made on site with concrete & a bucket of water.
The dwarven dream, concrete the entire overworld over all the dirt rivers and seas (technically by that method, you could actually dam and kill a river with concrete by destroying its entry point, seas too by making a sea-wall)
