ANSWERS A+ GRADED. Buy Quality Materials!
Which of the following tools is sufficient for the compacting of concrete in a small
project?
Hand tamper
At 50°F, how long should the concrete be protected to attain sufficient strength
(normally 500 Psi)?
48 Hours
Which of the following arrangements can be used to keep the concrete at the
recommended 50°F temperature for allowing proper setting?
Heaters OR Thermal blankets
What is the 'Swell Factor' for sandy loam soil when performing excavation work
for a concrete structure?
About 1.1 to 1.2
Which of the following building specification and cost estimating standard
systems is accepted as ASTM standard?
UniFormat System
Which of the following factors directly impact each other in the process of cost
estimation for a concrete building project?
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?
Decomposing of a task into doable, measureable, estimable , and schedulable units
Which of the following statements is correct about the finishing of a concrete?
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?
More than 10 cubic meters
What type of release oil is commonly used for the construction of wooden forms
in the concrete industry?
Paraffin base oil
Initial and final setting time values of concrete are normally considered from:
Mixing of water into cement material
Form-exposed corners and edges are commonly beveled to avoid any chipping
by using:
Chamfer strips
, Which of the following are the basic crafts used in estimating the concrete
construction cost in the industry?
Ironworker, Carpenter, Teamster, Cement mason
Which of the results of a concrete slump test has the highest workability?
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?
78"
Which of the following factors should be estimated as earthwork components in
project planning?
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?
Each 100 cubic yards
What are the recommended sizes of granular for a floor slab or foundation of a
small-to medium-size building?
4" to 6"
Which of the following are the main objectives of applying sealers on exterior
concrete surfaces?
To keep salt and water out of the concrete
What is the slab curling impact of direct placement of concrete on the moisture
barrier as indicated by American Concrete Institute guidelines?
Slab curling increases
Which of the following activities are recommended before placing the concrete
into the forms?
Application of form release oil and water
Which of the following is the standard spacing commonly used between two
adjacent expansion joints on a 4" thick concrete slab?
10 to 12 feet
Explanation:
The general rule of thumb is that the spacing should be 2 ½ feet for each single inch of
slab thickness.
