-One sample each was taken from three separate fine aggregate stockpiles, and results from their moisture tests are provided in the table below. :

Measure	Sample A	Sample B	Sample C
Stockpile Sample Mass (g) Mass when Sample is oven-dried (g) Absorption (%)	521.0 491.6 2.5	522.4 491.7 2.4	523.4 492.1 2.3

 What  is (a) stockpile moisture content, and (b) free moisture content, respectively, for Sample A when expressed as percentages?

	a.	a) Total Moisture Content = 59.8% , b) Free Moisture Content = 3.48%
	b.	a) Total Moisture Content = 2.5% , b) Free Moisture Content = 5.3%
	c.	a) Total Moisture Content = 5.98% , b) Free Moisture Content = 3.48%
	d.	a) Total Moisture Content =521 , b) Free Moisture Content = 491.6

 

2-How much water (in grams) needs to be added to the oven-dry Sample B to bring it to the SSD moisture state?

	a.	11.8
	b.	2.4
	c.	30.7
	d.	12.5

 

3-How much water (in grams) need to be added to, or removed from Sample C to bring its moisture content to the SSD state?

 

	a.	Remove 20.0 grams
	b.	Remove 2.3 grams
	c.	Add 2.3 grams
	d.	Add 11.3 grams
