Which of the following tools is sufficient for the compacting of
concrete in a small project? - answer Hand tamper
At 50°F, how long should the concrete be protected to attain
sufficient strength (normally 500 Psi)? - answer 48 Hours
Which of the following arrangements can be used to keep the
concrete at the recommended 50°F temperature for allowing
proper setting? - answer Heaters OR Thermal blankets
What is the 'Swell Factor' for sandy loam soil when performing
excavation work for a concrete structure? - answer About 1.1 to
1.2
Which of the following building specification and cost estimating
standard systems is accepted as ASTM standard? - answer
UniFormat System
Which of the following factors directly impact each other in the
process of cost estimation for a concrete building project? -
answer Interest rate, Holding cost, Cost escalation
Which of the following points are true about Work Breakdown
Structure (WBS) in the planning of a construction project? -
,answer Decomposing of a task into doable, measureable,
estimable , and schedulable units
Which of the following statements is correct about the finishing of
a concrete? - answer Concrete should be finished once bleed
water and surface sheen disappear
An excavation of 10 cubic meters is done on any soil. Which of the
following statements is true about the refilling volume of that
excavation with the same type of soil material? - answer More
than 10 cubic meters
What type of release oil is commonly used for the construction of
wooden forms in the concrete industry? - answer Paraffin base oil
Initial and final setting time values of concrete are normally
considered from: - answer Mixing of water into cement material
Form-exposed corners and edges are commonly beveled to avoid
any chipping by using: - answer Chamfer strips
Which of the following are the basic crafts used in estimating the
concrete construction cost in the industry? - answer Ironworker,
Carpenter, Teamster, Cement mason
Which of the results of a concrete slump test has the highest
workability? - answer True Slump
, Explanation:
Workability is the ease or difficulty of placing concrete in a
particular location. For example, a stiff but plastic mix with large
aggregate would be workable in large open form but not in a wall
with closely spaced reinforcement. Please note that the slump
test is NOT a measure of workability, and it should not be used to
compare mixes of entirely different proportions or containing
different kinds of aggregate.
What is the maximum depth of a foundation footing commonly
used in concrete construction? - answer 78"
Which of the following factors should be estimated as earthwork
components in project planning? - answer ALL OF THESE
-Rough grading, Excavation, Soil backfilling
-Soil compacting, Fill material compacting, Excavation
-Excavated soil hauling, Soil backfilling, Rough grading
According to American Concrete Institute ACI-301 standard, what
is the maximum volume of concrete that requires a strength test
of concrete? - answer Each 100 cubic yards
What are the recommended sizes of granular for a floor slab or
foundation of a small-to medium-size building? - answer 4" to 6"
