Question

For M25 concrete with creep coefficient of 1.5, the long-term static modulus of elasticity (expressed in MPa) as per the provisions of IS:456-2000 is ________.
10000

Open in App

Solution

The correct option is A 10000
Long term static modulus of elasticity

$= \frac{E}{1 + θ}$

$= \frac{5000 \sqrt{f_{C K}}}{1 + θ} = \frac{5000 \times \sqrt{25}}{2.5}$

$= 10000$ MPa
