Q1:

Creep of concrete is assumed proportional to the stress if the stress does not exceed .......of the characteristic compressive strength

A 15%

B 20%

C 25%

D 33%

E 50%

ANS:D - 33%

Here, the strain under constant load is considered directly proportional to applied stress until concrete exceeds (greater/less) by a value of 33% of 28 days compressive Nominal stress.
