Reinforced Concrete is a craftable building material. It is one of the most durable building blocks in the game. Reinforced Concrete requires 1 Rebar Frame, 4 Wood Planks, and 1 Concrete Mix (Rebar Frames and Concrete Mix are unlocked after reading the Set In Concrete Recipe Book). Destroying a Reinforced Concrete block will yield Scrap Iron.
The following tools can be used to place the Wood Planks onto the Rebar Frame:
Stage 2 is a rather weak block and may only be used as a mold; when pouring the concrete mix and creating Reinforced Concrete, it becomes a very strong structure. Stage 3 is not achievable with a tool like Stage 1: one must right-click on a Stage 2 block while holding Concrete Mix. It becomes Poured Concrete, which is fairly weak; if broken in this stage, it drops nothing. After 1 to 2 game hours, the concrete dries, the Concrete Form disappears and Reinforced Concrete is finished.
- Reinforced Concrete has 4 "destruction stages"; it can be repaired with a tool or by pouring Concrete Mix on it.
