Question

The modulus of elasticity (E) of concrete is given by

• A. $E=1000f_{ck}$
• B. $E=5700\sqrt{f_{ck}}$
• C. $E=5500\sqrt{f_{ck}}$
• D. $E=10,000\sqrt{f_{ck}}$

Answer 1

The correct option is B $E=5700\sqrt{f_{ck}}$

$AsperIS:456-1978,E_c=5700\sqrt{f_{ck}}$

$AsperIS:456-2000,E_c=5000\sqrt{f_{ck}}$
