A 627-g sample of sand was found to have the following amounts of material retained on each sieve/pan: 3/8 in. = 22 g, No. 4 = 45 g, No. 8 = 96 g, No. 16 = 122 g, No. 30 = 163 g, No. 50 86 g, No. 100 = 51 g, No. 200 = 30 g, pan= 11 g a. Calculate the fineness modulus of the sand. b. Is this sieve analysis valid for acceptance purposes? Explain why. c. Does the sand meet the particle size criteria of ASTM C 33. Fully justify your answer (list and check all relevant criteria from ASTM C33)

A 627-g sample of sand was found to have the following amounts of material retained on
each sieve/pan:
3/8 in. = 22 g, No. 4 = 45 g, No. 8 = 96 g, No. 16 = 122 g, No. 30 = 163 g.
No. 50 86 g, No. 100 = 51 g, No. 200 = 30 g, pan = 11 g
a. Calculate the fineness modulus of the sand.
b. Is this sieve analysis valid for acceptance purposes? Explain why.
c. Does the sand meet the particle size criteria of ASTM C 33. Fully justify your answer
(list and check all relevant criteria from ASTM C33)
