Q: Grading of sand cause great variation in:
  • A. Workability of concrete.
  • B. Strength of concrete.
  • C. Durability of concrete.
  • D. All the above.
Correct Answer: Option D - Sand are classified two types– (i) Well graded sand. (ii) Poorly graded sand. A well graded sand that particles of a wide range. A well graded sand with a minimum void ratio 0.35 and maximum void ratio 0.70 so, it affects the strength of concrete. Grading of sand cause great variation in workability of concrete/strength of concrete as well as durability of concrete.
