1. Define C117 The determination of the
amount of material finer than a
75-um (No.200) sieve
2. What is the significance of C136? -To determine the grading of
materials,
-compliance of particle size dis-
tribution,
-provide data for control of pro-
duction of various aggregate
-developing relationships con-
cerning porosity and packing
3. What procedure should always be used unless oth- Procedure A
erwise specified in c117?
4. What is an appropriate wetting agent to use for Water or any dispersing agent
sieving through a No.200 sieve? that will promote separation of
the fine materials
5. What should the temperature of the oven be when 110 °C (+-5)
drying samples?(C117)
6. If used, how much wetting agent should be used in Enough to produce a small
procedure B? C117 amount of suds when the sam-
ple was agitated
7. Report the amount retained by wash by....?(C117) <10%-report to the .1%
>10%-report to the nearest
whole number
8. How long do you sieve material? C136 so that not more than 1% of ma-
terial retained on any sieve will

9. How accurate shall balances be fo fine aggregate? readable to the nearest .1 Gram
C136 or .1%
10. How accurate shall balances be for course aggre- readable to the nearest .5 gram
gate or mixtures? C136 or nearest .1%
11. What is the significance of C117? Accurate determination of mate-
rial finer than 75-um in mineral
aggregate by washing
12. What practice is used for sampling aggregate? D75
13. The investigation of potential sample material A responsible, trained and ex-
should be performed by....? D75 perienced person
14. What should a stockpile be visually inspected of? Discernable Variations
D75
15. Where shall a sample be obtained where practica- From the finished product
ble?D75
16. After a sample is obtained what shall not be done Further crushing or manual re-
unless required for testing purposes? D75 duction
17. What shall be done if there are any discernable Corrective action shall be taken
Variations in a stockpile? D75 to establish homogeneity in the
material
18. If it is necessary to indicate the degree of variation Separate samples shall be
in a stockpile, what shall be done? D75 drawn from separate areas of
