alleryStart learning →Per §2.2.14, the Fineness Modulus range that corresponds to MEDIUM sand is:
A2.6 to 2.9
B2.2 to 2.6
C1.5 to 2.0
D2.9 to 3.2
Answer & Solution
Correct answer: A. 2.6 to 2.9
1. §2.2.14 provides three FM bands: Fine sand 2.2 to 2.6, Medium sand 2.6 to 2.9, Coarse sand 2.9 to 3.2.
2. A sand with FM > 3.2 is considered unsuitable for making concrete.
