NICET Soils Level 1 Questions & Answers
1. Define C117
Answer The determination of the amount of material finer than a 75-um (No.200) sieve
2. 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
3. What procedure should always be used unless otherwise specified in c117?-
Answer Procedure A
4. What is an appropriate wetting agent to use for sieving through a No.200
