Concrete — Factorio Production Calculator
Concrete is crafted in the assembling machine in 10 seconds, producing 10 per craft from 5 × Stone brick, 1 × Iron ore, 100 × Water. At 60 per minute you need 2 assembling machines, and the chain behind it draws on 3 raw resources: water, stone, iron ore.
Production chain for 60 Concrete / minute
| Item | Per minute | Machines | Machine |
|---|---|---|---|
| Concrete | 60 | 2 | Assembling machine |
| Stone brick | 30 | 1.6 | Furnace |
Raw materials
| Resource | Per minute |
|---|---|
| Water | 600 |
| Stone | 60 |
| Iron ore | 6 |
Machine counts are not rounded up. Add a little headroom in game — belt throughput and inserter speed usually mean you want 5-10% more than the exact number.
Concrete recipe
| Machine | Crafting time | Output | Ingredients |
|---|---|---|---|
| Assembling machine | 10 s | 10 | Stone brick × 5, Iron ore × 1, Water × 100 |
What the whole chain needs
60 concretes per minute pulls in 1 intermediate product, and the whole tree comes to 4 machines across 2 machine types, fed by 3 raw resources. The table above already sums demand across every branch — if copper cable is used by two recipes, you see the total, not one of them.
Belt check: the busiest input here moves 600 per minute, which is 0.67 of a yellow belt's 900 per minute. Above 1.0 and you need a second belt (or a faster tier) before the machines themselves become the limit.
What uses concrete
6 base-game recipes consume concrete, sorted by how much each one takes:
- Rocket silo — 1000 per craft
- Nuclear reactor — 500 per craft
- Centrifuge — 100 per craft
- Artillery turret — 60 per craft
- Refined concrete — 20 per craft
- Hazard concrete — 10 per craft
What concrete is made from
- Stone brick — 5 per craft
FAQ
How many assembling machines do I need for 60 concretes per minute?
2 assembling machines. One at standard speed produces 30 per minute, so 60 ÷ that number is the count. The calculator above rounds nothing — add 5-10% headroom for belt and inserter losses in a real factory.
How much raw ore does concrete take?
At 60/min the chain consumes 600 water per minute, 60 stone per minute, 6 iron ore per minute. Those numbers are the theoretical minimum — mining productivity research and productivity modules both reduce them.
Is concrete needed for science packs?
Not directly. It feeds Rocket silo and Nuclear reactor, and those in turn feed the science packs. Open the science pack page to see the demand that lands on this recipe.
