AFCS Hierarchy Data - --Answers----Super Component,
component, facility, construction activity, resources/NSN
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
