What is the value of Young's modulus for M25 concrete as per IS 456 : 2000?

Concept:

Elastic modulus of concrete,

\({E_C} = 5000 \times \sqrt {{f_{ck}}} \)

Where,

fck = grade of concrete

Long term elastic modulus of concrete

\({E_θ } = \frac{{{E_c}}}{{1 + θ }}\)

θ = creep coefficient

Calculation:

fck = 25 MPa

∴\({E_C} = 5000 \times \sqrt {{25}} =25000 \; N/mm^2\) = 2.5 × 104 MPa
