Q: How does the age of concrete affect its compressive strength?, consider the age limit as 28 days with continued curing.
  • A. Compressive strength increases as the age of concrete increases
  • B. Compressive strength increases upto an age 14 days and continues to decrease on further curing
  • C. Age of concrete does not affect the compressive strength of concrete
  • D. Compressive strength decreases upto an age 7 days and continues to decrease on further curing
Correct Answer: Option A - Concrete develops strength with age due to continued hydration. Initially rate of gain of strength is fast which reduces as time increases. Compressive strength of concrete depends upon grade, type of cement, curing environmental conditions. The design based on 28 days strength.
