Hazard concrete — Factorio Production Calculator
Hazard concrete is crafted in the assembling machine in 0.25 seconds, producing 10 per craft from 10 × Concrete. At 60 per minute you need 0.05 assembling machines, and the chain behind it draws on 3 raw resources: water, stone, iron ore.
Production chain for 60 Hazard concrete / minute
| Item | Per minute | Machines | Machine |
|---|---|---|---|
| Hazard concrete | 60 | 0.05 | Assembling 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.
Hazard concrete recipe
| Machine | Crafting time | Output | Ingredients |
|---|---|---|---|
| Assembling machine | 0.25 s | 10 | Concrete × 10 |
What the whole chain needs
60 hazard concretes per minute pulls in 2 intermediate products, 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 hazard concrete
No base-game recipe consumes hazard concrete — it is an end product. Once you build it, the chain stops here, which makes it a good target if you only want to size the sub-factory that feeds your mall.

FAQ
How many assembling machines do I need for 60 hazard concretes per minute?
0.05 assembling machines. One at standard speed produces 1,200 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 hazard 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.
Machine counts assume bare machines at standard speed. Recipe data comes from the game's own prototypes (PlayerCalc, Factorio 2.0 base game). Not affiliated with Wube Software.
