CORRECTLY WELL DEFINED ANSWERS
LATEST ALREADY GRADED A+
Super Component: - ANSWERS-Group of one or more
components to provide a specific service. There are Five
AFCS super components
Component: - ANSWERS-group of one or more facilities
designed to provide a specific service. There are over 200
AFCS components
Facility: - ANSWERS-any item that serves a purpose and
contains one or more construction activities. There are over
700 AFCS facilities
Construction activity: - ANSWERS-specific construction task
subordinate to a larger construction project. Self contained
unit that identifies costs, parts/materials, types and amount
of labor, equipment, construction specifications and any
,associated drawings required to complete the constructed
task. Smallest work item level in the hierarchal database
Resource/NSN: - ANSWERS-equipment and/or labor
Concrete is composed of - ANSWERS-Concrete is composed
of Portland cement, water, aggregates, air, admixtures
Types of Concrete Reinforcement - ANSWERS-Temperature
and Shrinkage Steel
Structural Steel
Reinforcement = metal mesh or rebar
Only place in areas of tension
Water - ANSWERS-8.33 lbs/gallon or 62.4lbs/cubic foot
If it is good enough to drink, it is good enough for concrete
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
