Question

The modulus of rupture of concrete gives

• A. the direct tensile strength of the concrete
• B. the direct compressive strength of the concrete
• C. the tensile strength of the concrete under bending
• D. the characteristic strength of the concrete

Answer 1

The correct option is C the tensile strength of the concrete under bending

Tensile strength of concrete in flexure is called flexural strength ( Modulus of rupture)

Note : As per IS : 456:2000
Modulus of rupture,
$f_{cr}=0.7\sqrt{f_{ck}}N/m{m}^2$
