Equipment:

Mechanical Sieve Shaker

Sieve Set: #$4,$#$8,$#$16,$#$30,$#$50,$#$100,$ and pan

Procedure:

Select a sample of fine aggregate that is in a thoroughly mixed and moist condition.

Dry the sample to constant weight at a temperature of $100\frac{+}{-}5C.$

Weigh a specimen of approximately $500g$ of oven$-$dried sand.

Make sure each sieve is clean before using. Clean with a soft bristle brush.

Nest the sieves in order of decreasing size of opening from top to bottom and place the sample on the top sieve.

Agitate the sieve stack for $10$ minutes.

Calculations:

Calculate the cumulative $\%$ retained, and cumulative $\%$ passing for the fine aggregate. Calculate the fineness modulus for the fine aggr pyate. NOTE: The fineness modulus calculation DOES NOT include the weight of the material in the pan.

Fineness Modulus: ${\displaystyle \underset{?}{\overset{?}{}}}\%$ Cumulative Retained $/100=$
