1. Which of the following is used to measure the quantity of earthwork in excavation?
A. Cubic meter
B. Square meter
C. Linear meter
D. Cubic foot
Answer: A) Cubic meter
Rationale: The quantity of earthwork for excavation is measured in cubic meters as it
represents the volume of material being excavated.
2. What is the main function of a concrete slump test?
A. To determine the compressive strength
B. To measure the workability of concrete
C. To measure the curing time
D. To measure the moisture content
Answer: B) To measure the workability of concrete
Rationale: The slump test is used to measure the workability of fresh concrete, or its
ability to flow when placed in a form.
,3. If the length of a column is doubled, the buckling load will be:
A. Doubled
B. Halved
C. Four times the original load
D. One-fourth the original load
Answer: D) One-fourth the original load
Rationale: According to the formula for buckling load Pcr=π2EIL2P_{cr} =
\frac{\pi^2EI}{L^2}Pcr=L2π2EI, if the length LLL is doubled, the load capacity will
be reduced by a factor of four.
4. What is the most commonly used type of cement in construction?
A. Ordinary Portland Cement (OPC)
B. Rapid Hardening Cement
C. Sulfate Resisting Cement
D. White Cement
Answer: A) Ordinary Portland Cement (OPC)
Rationale: Ordinary Portland Cement (OPC) is the most commonly used cement in
construction due to its versatility and general-purpose use.
, 5. What is the value of Poisson’s ratio for most building materials?
A. 0.1 to 0.3
B. 0.25 to 0.4
C. 0.3 to 0.5
D. 0.5 to 0.7
Answer: B) 0.25 to 0.4
Rationale: Poisson’s ratio for most building materials, including concrete and steel,
typically ranges from 0.25 to 0.4.
6. Which of the following is the primary material used for the construction of
highways?
A. Steel
B. Concrete
C. Bitumen
D. Wood
Answer: C) Bitumen
Rationale: Bitumen is used primarily in the construction of flexible pavements
(highways) because of its binding and waterproofing properties.
A. Cubic meter
B. Square meter
C. Linear meter
D. Cubic foot
