Early Concrete Slabs

You can build this setup as your first Concrete Production, but just build one of each building like i did on the picture. If your factory grows and you need more Concrete Slabs than build the rest step by step. You can use and upgrade it until you research the big Crusher, than you have to rebuild the crushing section. You have to provide Limestone, Coal, Water, Rock, Sand and Slag to run it. I preset this build to use Slag and Manufactured Sand at first. If you research Rotary Kiln (Gas) you can easily exchange the Coal Storage with a Fuel Gas Storage. Let me know if something isn´t working.
