Question : 116 of 200

Marks: +1, -0

As per IS 456 : 2000, using working stress method, the modular ratio of M 25 grade of concrete for permissible compressive strength due to bending in concrete

σ_\cbc = 8.5

MPa is:

14.39
12.04
15.63
10.98

Validate

Solution:

As we know that,
Modular ratio =

280/σ_\cbc =280/{3×8.5}=10.98.
