What is the flexural strength of M20 grade concrete?
Flexural strength of concrete/ Bending tensile strength of concrete/Modulus of rupture of concrete (f cr) is given by. f cr = 0.7 × √f ck . ∴ Flexure strength of concrete is determined as a modulus of rupture. Calculation: Given, Grade of concrete is M20 . i.e. f ck = 20 MPa. Flexural Strength = 0.7 × √20 = 3.13 MPa . Additional Information
