WITH CORRECT ANSWERS
Question :Define C117
Correct answer:The determination of the amount of material
finer than a 75-um (No.200) sieve
Question :What is the significance of C136?
Correct 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
