Q: As per IS 2386 (1963), the aggregate crushing value is calculated by using a single sized aggregate, which is.
  • A. passing 12.5 mm and retained on 10 mm sieve
  • B. passing 4.75 mm and retained on 2.36 mm sieve
  • C. passing 40 mm and retained on 20 mm sieve
  • D. passing 20 mm and retained on 10 mm sieve
Correct Answer: Option A - As per IS 2386 (Part IV) - 1963, determine of aggregate crushing value • Aggregate passing through a 12.5 mm IS sieve and retained on a 10 mm IS sieve are used as the test sample which is known as single sized aggregate. • The 'ten percent fines' value gives a measure of the resistance of an aggregate to crushing that is applicable to all aggregates.
