Concrete Factory | Anno 1800 Wiki | Fandom
Concrete factory turns steel and cement into reinforced concrete, the last construction material. It can be built only in the Old World. It takes 60 seconds to produce 1 ton of reinforced concrete from 1 ton of steel and 1 ton of cement so the production rate is 1 ton of reinforced concrete per minute. Productivity can be changed by adjusting working conditions, using items and electricity.
