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
, 2
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
, 3
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
