After installing this mod, all factories set to produce Concrete had their recipe removed. I can only see Concrete from my personal inventory crafting panel, but cannot craft because it requires a factory. Here is what I see in the modinfo when hovering over the personal Concrete recipe: "Base mod > AAI Industry > Crush Bricks".

That is very strange. Perhaps a namespace clash? My mod only defines a new recipe.

Uploading a bugfix release that hopefully solves this. Please report back whether that fixes the problem. If not, I'll have to add an incompatibility.

Ok, verified the bugfix preserves Concrete recipes, though it looks like the Crush Bricks Into Stone recipe has its name as an Unknown Key now:

I wonder if it has something to do with one of the mods enabling Stone to be used for gravel paths?

Everything seems to be in order with version 2.0 of the mod.

This problem still exists in the last version (1.1.1)

I'll get right on that
