Question 5 (4 points)

Using the following data, determine the moisture content, absorption,

and free moisture in a sample of fine aggregate. If 75lb of the sample is

used in the mix design of concrete, what is the amount of water

contributed to the mix by the fine aggregate (FA)?

Initial sample weight= 1.2 lb

Saturated surface dry weight= 1.14 lb

Oven-dry weight = 1.06 lb

Question 5 options:

free moisture is 5.7%

the amount of water contributed to the mix is 5.3 lb

absorption is 7.5%

Moisture content is 13.2%

the amount of water contributed to the mix is 4.281b

absorption is 10.3%

free moisture is 7.0%

Question 6

Aggregates from three sources having bulk specific gravities of 2.753,

2.649 and 2.689 were blended at a ratio of 70:20:10 by weight.
