Question

The coarse sand has fineness modulus in the range of

• A. $2.2-2.4$
• B. $2.4-2.6$
• C. $2.6-2.9$
• D. $2.9-3.2$

Answer 1

The correct option is D $2.9-3.2$

Fineness modulus : It is a numerical index of fineness, giving some idea about the mean size of the particles in the aggregates.

Type of sand	Fineness modulus range
Fine sand	$2.2-2.6$
Medium sand	$2.6-2.9$
Coarse sand	$2.9-3.2$
