Q: As per IS 10262 : 2019, what is the approximate amount of entrapped air to be expected in normal (non-air-entrained) concrete, when 10 mm Nominal Maximum Size of Aggregate is used in making concrete?
- A. 1.5
- B. 1.0
- C. 0.5
- D. 2.0
Correct Answer:
Option A - Estimation of air content–Approximate amount of entrapped air to be expected in normal (non air-entrained) concrete is given as per IS 10262-2019.
