Concrete compressive strength at an age of t days, fck(t)
Eurocode 2 part 1-1: Design of concrete structures 3.1.2 (5)
The concrete compressive strength at an age of t days is:
| fck(t) = fcm(t) - 8 (MPa) | for 3 < t < 28 days |
| fck(t) = fck | for t ≥ 28 days |
where:
- fck
- is the characteristic compressive cylinder strength of concrete at 28 days according to Table 3.1
- fcm(t)
- is the mean concrete compressive strength at an age t days
- t
- is the age of the concrete.
This application calculates the compressive strength fck(t) from your inputs. Intermediate results will also be given.
