When is an aggregate sample considered at constant mass? (C29) - SOLUTION-When the 2
sample weights taken an hour apart is less than .1%
What is the formula for Bulk Density? (C29) - SOLUTION-(mass of agg. and measure - mass of
measure) /volume of measure
What is is maximum size to use the jigging procedure? (C29*) - SOLUTION-Greater than 1.5", but
no greater than 5"
What is the formula for void content? (C29) - SOLUTION-100[(bulk specific gravity X density of
water) - Bulk Density of agg./ bulk specific gravity X density of water
bulk density be reported to the nearest.... (C29) - SOLUTION-1 LB/ft^3
What is the significance of ASTM C31? - SOLUTION-It provides the requirements for making,
curing, protecting and transporting concrete specimens
, If specimens are made and standard cured what can the test results be used for? (C31) -
SOLUTION--Acceptances for specific strength
-checking adequacy of mixture proportions
- Quality Control
if specimens are field cured what can the test results be used for? (C31) - SOLUTION-Determine
if a structure can be put in service
-comparison with test results of standard cure specimens
-form removal time requirements
What is Bulk Density used for? (c29) - SOLUTION-Determining Mass/volume relationship for
conversions in purchase agreements
What is the dimensions of plate glass? (C29) - SOLUTION-1/4" thick and at least 1" larger than
the diameter of the measure
What are the requirements for a thermometer? (C1064) - SOLUTION-has a range of at least 30-
120°F and readable to the nearest 1°F
When drying aggregate to constant mass, What should the temperature of the oven be? (C29) -
SOLUTION-230°F (+/- 10°F)
What are the specifications of a tamping rod? - SOLUTION-A round, smooth, straight, steel rod.
The length should be at least 4" greater than the depth of the mold, but no greater than 24"
When using the a 4"x 8" cylinder, What are the rod specifications? - SOLUTION-straight, steel,
w/hemispherical tip 3/8" in diameter (+-1/16")
