EXAM – ECCC GE EXAM 1 WITH CORRECT
ACTUAL QUESTIONS AND CORRECTLY
WELL DEFINED ANSWERS LATEST
ALREADY GRADED A+
Water-Cement Ratio - ANSWERS-The W/C ratio is
determined by the strength, durability, and watertightness
requirements of the hardened concrete. These are usually
determined by the structural-design engineer, but a
tentative mix proportion can be determined from
knowledge of prior jobs.
Trail Batch Method: - ANSWERS-time constrained; use the
job materials and make samples
Absolute Volume Method - ANSWERS-mathematically based
,Concrete Quality Control - ANSWERS-slump, moisture
deformation on the sand, air meter, cylinders or beam
Slump - ANSWERS-Allowable slump depends on mix design
Does not apply if concrete contains aggregates larger than 2
inches
Moisture Deformation on Sand - ANSWERS-Samples should
be taken from 6-8 inches below surface of piled sand
Air Meter - ANSWERS-4-6%
Cylinders or Beams - ANSWERS-3-4 cylinders a day or every
50 cubic yard
Base Camp Principles (the 4 S's) - ANSWERS-Scalability:
tolerate population changes and incorporate changes
Sustainability: maintain effectiveness without strain
Standardization: fast and to standard
Survivability: maintain combat fire
, Types of base camps - ANSWERS-Base
Base Camp
Intermediate Staging Base
Forward Operation Base
Base Camp Classification - ANSWERS-Based on duration,
purpose, and size
Base Camp Standards - ANSWERS-Initial
Temporary: 5 years
Semi-permanent: 10 years
DC vs AC - ANSWERS-Direct Current: electrical current that
flows one direction only
Alternating Current: reverse direction at regular intervals
Laws (ohms, power) - ANSWERS-Power Law: P (watts) = I
(amps) x E (volts)
Ohm's Law: R (ohms) = E (volts) / I (amps)
