Concrete 320/m

Uses 4 Refineries to produce 320/m Concrete. Good Mid-Game set up. Can link up more of these to get even more. This is my first BP, so I hope it works well for you like it has for me. 480 Limestone, 400m3/Water. This Picture I uploaded was using 6 refineries! Feel free to tailor it to your design! Uses Alt Recipe : Wet Concrete that is already programmed into each Refinery!
