Question

Fine Aggregates should pass through which IS sieve?

(a) 2.35mm

(b) 45µ

(c) 4.75mm

(d) 75µ

This question was posed to me in examination.

This intriguing question comes from Fine Aggregates topic in chapter Materials for Construction of Basic Civil Engineering

Answer 1

Correct answer is (c) 4.75mm

The best explanation: 4.75mm IS sieve is the aggregate size deciding sieve.  Anything retained on sieve is coarse aggregate and the ones that pass through sieve are fine aggregates.
