Cven 342 midterm /Complete Real Exam.
Nonhomogeneous - CORRECT ANSWERS -properties vary with location in material
Homogeneous - CORRECT ANSWERS -material has the same properties at all
locations
Anisotropic - CORRECT ANSWERS -properties vary with direction
Isotropic - CORRECT ANSWERS -properti...
, Creep - CORRECT ANSWERS -The time-dependent permanent deformation that
occurs under stress; for most materials it is important only at elevated temperatures.
Aggregates - CORRECT ANSWERS -are defined as inert, granular, and inorganic
materials.
Aggregate Gradation - CORRECT ANSWERS --distribution of particle sizes expressed
as a percent of total weight
-determined by sieve analysis
-plot: sieve size vs cumulative percent passing by weight.
Uniformly Graded - CORRECT ANSWERS -- Few points of contact
- Poor interlock (shape dependent)
- High permeability
Gap Graded - CORRECT ANSWERS -- Only limited sizes
- Good interlock
- Low permeability
Open Graded - CORRECT ANSWERS -Insufficient fines
0.45 Power Gradation Chart - CORRECT ANSWERS -- A log plot of sieve size vs
percent passing (Max Density Gradation).
- The line from the origin to the max size is called the theoretical maximum density
curve.
Gradation Specs: Bands and Control Points - CORRECT ANSWERS -Band: the region
in between the spec limits on the gradation chart.
Control points: points that show the spec limits on the gradation chart.
Nominal Maximum Aggregate Size (NMAS) - CORRECT ANSWERS -One size larger
than the first sieve to retain more than 10%.
Maximum Aggregate Size (MAS) - CORRECT ANSWERS -One size larger than
nominal maximum size.
Fineness Modulus - CORRECT ANSWERS -A measure of the fine aggregates
gradation.
Range: 2.3 - 3.1
