Concrete Technology & RCCModulus of elasticityMEDIUM
Choose the correct answer
A
Ec = 5000 sqrt(fck)
B
Ec = 500 sqrt(fck)
C
Ec = 5700 sqrt(fck)
D
Ec = 0.7 fck
Correct Answer
A. Ec = 5000 sqrt(fck)
Why is this the answer?
IS 456 gives Ec = 5000 sqrt(fck), where fck is in N/mm2. Reference: Clause 6.2.3.1 | Page: verify from your official BIS copy/PDF pagination
