Question

The modulus of rupture of concrete in terms of its characteristics cube compressive strength (fck) in mpa according to is 456-2000 is

Answer 1

Missing options in question :-

a) 5000 fck

b) 0.7 fck

c) 5000 √ fck

d) 0.7 √ fck

Answer :- 0.7 √ fck

Let Fcr we the modulus of rupture

Characteristics cube compressive strength in mpa - fck

Fcr = 0.7 √ Fck

So , the correction option is (d) = d) 0.7 √ fck
