Secant modulus of elasticity of concrete at an age of t days, Ecm(t)
Eurocode 2 part 1-1: Design of concrete structures 3.1.3 (3)
Variation of the modulus of elasticity with time can be estimated by:
| Ecm(t) = (fcm(t) / fcm)0,3 Ecm | (3.5) |
where:
- Ecm(t)
- is the secant modulus of elasticity of concrete at an age of t days
- Ecm
- is the secant modulus of elasticity of concrete at 28 days
- fcm(t)
- is the mean concrete compressive strength at an age t days
- fcm
- is the mean compressive strength at 28 days according to Table 3.1.
This application calculates the modulus of elasticity Ecm(t) from your inputs. Intermediate results will also be given.
