Question

Which IS code gives the grading of sand?

(a) IS 456

(b) IS 383

(c) IS 2368

(d) IS 1542

I have been asked this question during a job interview.

My question is from Source and Classification of Sand in division Materials for Construction of Basic Civil Engineering

Answer 1

The correct answer is (b) IS 383

To explain I would say: IS code 383-1970 gives the classification of sand based on the grading. There are 4 grading zones. For each sieve size, there is a specific % of particle passing through that sieve, denoted in the respective zone.
