Define C117 - aNSwEr-The determination of the amount of material finer than a 75-um (No.200) sieve
What is the significance of C136? - aNSwEr--To determine the grading of materials,
-compliance of particle size distribution,
-provide data for control of production of various aggregate
-developing relationships concerning porosity and packing
What procedure should always be used unless otherwise specified in c117? - aNSwEr-Procedure A
What is an appropriate wetting agent to use for sieving through a No.200 sieve? - aNSwEr-Water or any
dispersing agent that will promote separation of the fine materials
What should the temperature of the oven be when drying samples?(C117) - aNSwEr-110 °C (+-5)
If used, how much wetting agent should be used in procedure B? C117 - aNSwEr-Enough to produce a
small amount of suds when the sample was agitated
Report the amount retained by wash by....?(C117) - aNSwEr-<10%-report to the .1%
>10%-report to the nearest whole number
How long do you sieve material? C136 - aNSwEr-so that not more than 1% of material retained on any
sieve will pass during 1 minute of hand sieving
, How accurate shall balances be fo fine aggregate? C136 - aNSwEr-readable to the nearest .1 Gram or
.1%
How accurate shall balances be for course aggregate or mixtures? C136 - aNSwEr-readable to the
nearest .5 gram or nearest .1%
What is the significance of C117? - aNSwEr-Accurate determination of material finer than 75-um in
mineral aggregate by washing
What practice is used for sampling aggregate? - aNSwEr-D75
The investigation of potential sample material should be performed by....? D75 - aNSwEr-A responsible,
trained and experienced person
What should a stockpile be visually inspected of? D75 - aNSwEr-Discernable Variations
Where shall a sample be obtained where practicable?D75 - aNSwEr-From the finished product
After a sample is obtained what shall not be done unless required for testing purposes? D75 - aNSwEr-
Further crushing or manual reduction
What shall be done if there are any discernable Variations in a stockpile? D75 - aNSwEr-Corrective
action shall be taken to establish homogeneity in the material
If it is necessary to indicate the degree of variation in a stockpile, what shall be done? D75 - aNSwEr-
Separate samples shall be drawn from separate areas of the pile
What increases when sampling from the beginning or the final few tons of a conveyor belt? D75 -
aNSwEr-The potential of obtaining segregated material
When should method A be used in a standard proctor? D698 - aNSwEr-When 25% or less material is
retained on a No. 4 sieve
