NICET Soils level 1 Exam(Answered)2023Define 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 NICET Soils level 1 Exam(Answered)2023
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
When should method B be used for standard proctor? D698 - Answer When 25% or less material is retained on a 3/8" sieve
When should method C be used for standard proctor? D698 - Answer When 30% or less material is retained on a 3/4" sieve
When should a correction factor be established on a standard proctor? D698 - Answer When the test specimen contains more than 5% of oversize fractions
for purposes of comparing measured or calculated values, what shall the value be rounded to? D698 - Answer The nearest decimal or significant digit
The procedures in D698 are considered...? - Answer industry standard
Define Standard Effort....D698 - Answer 12,400 ft-Ibf/ft3 compactive effort applied by
equipment in D698
Define Standard Optimum Water Content....D698 - Answer The molding water content at which soil can be compacted to the maximum dry unit weight using standard compactive effort
Define oversized fractions...D698 - Answer The portion of a sample that does not pass through the required sieve in D698
Laboratory compaction tests provide...D698 - Answer determination of the percent compaction and molding water needed to achieve engineering requirements
Soil placed as engineering fill is compacted to obtain what? D698 - Answer Sheer strength, compressibility or permeability
Success in executing the compaction controls of earth works is highly dependant on what? D698 - Answer The quality and experience of the contractor and inspector
