Concrete Thermal Expansion Calculator
Expansion of concrete (α = 12 µm/m·K) over your temperature range.
Almost identical to steel — THE coincidence that makes reinforced concrete possible at all.
Formula
Concrete Thermal Expansion Calculator is a free concrete thermal expansion for design engineers, metallurgists and QA inspectors — instant, accurate and 100% client-side, with the governing formula and reference shown next to the result so the number can be defended, not just quoted.
About Concrete Thermal Expansion Calculator

Frequently asked questions
What formula does the Concrete Thermal Expansion Calculator use?+
It computes ΔL = L × 12 µm/m·K × ΔT, per ASM Handbook Vol. 2 — CTE data. The formula is displayed under the result.
What should I keep in mind when using this calculator?+
Almost identical to steel — THE coincidence that makes reinforced concrete possible at all.
Where do the material property defaults come from?+
Defaults are standard handbook values (ASM, manufacturer datasheets, the cited standard). Always substitute certified values from your material's test certificate for critical work.
Is the Concrete Thermal Expansion Calculator free to use?+
Yes — completely free, no sign-up, no limits. It runs client-side in your browser, so inputs stay private and results are instant even on slow connections.
