This question was addressed to me in an interview for job.

This intriguing question comes from Cement Concrete Construction topic in portion Cement Concrete Construction of Construction & Building Materials

Answer 1

Correct answer is (a) Fineness modulus method

For explanation: The Tom fineness modulus is used to indicate an index number which is roughly proportional to the average size of the particle in the enter quantity of aggregates. The number of the BIS sieves used are from 80 mm to number 15, which are used to determine the fineness modulus.
