Construction Materials · Concrete: constituents, mix design, short-term and long-term properties · 1 mark · Multiple choice

Creep of concrete under compression is defined as the _____.

  1. increase in the magnitude of strain under constant stress
  2. increase in the magnitude of stress under constant strain
  3. decrease in the magnitude of strain under constant stress
  4. decrease in the magnitude of stress under constant strain

Show answer and explanation

Correct answer: (A) increase in the magnitude of strain under constant stress

Explanation

Creep is the time-dependent increase in strain of concrete under a sustained (constant) stress. The decrease in stress under a constant strain is relaxation.
