Question

4: The modulus of elasticity of M30 concrete as per 456-2000 and IS 456:1978 are ? 3621768054​

Answer 1

Explanation:

(viii) If you take away 6 from 6 times y, you get 60.

(ix) If you add 3 to one-third of z, you get 30.

Solution:

Question 5.

Write the following equations in statement forms.

Answer 2

Answer:

ANSWER: OPTION 3

Explanation:

The modulus of elasticity as per IS:456-1978

{ E }_{ c }=5700\sqrt { { f }_{ ck } } N/{ mm }^{ 2 }E

c

=5700

f

ck

N/mm

2

For M25

{ E }_{ c }=5700\sqrt { 25 }=28,500 MPa E

c

=5700

25

=28,500MPa
