EXAM QUESTIONS
QUESTION 1
Which of the following best describes a fundamental characteristic of water-reducing admixtures in
concrete construction?
A) They increase air content and enhance workability without affecting slump
B) They improve the impermeability of hardened concrete by altering its water-cement ratio
C) They reduce the water demand and increase the strength of the concrete, while maintaining its
workability
D) They decrease the strength of the concrete while increasing its workability and slump
CORRECT ANSWER
C) They reduce the water demand and increase the strength of the concrete, while maintaining its
workability
Trusted by thousands of students and professionals worldwide Page 1 of 26
, RATIONALE: Water-reducing admixtures are known to decrease the water demand in concrete, thereby increasing its
strength and workability. They also help maintain the concrete's slump by minimizing the need for additional water.
Option C accurately reflects this characteristic. Options A and B are incorrect because water-reducing admixtures do not
increase air content or directly improve impermeability. Option D is incorrect as it contradicts the primary purpose of
water-reducing admixtures.
QUESTION 2
What is the primary purpose of testing the soundness and setting characteristics of Portland Cement,
as specified in ASTM C150?
A) To determine the compressive strength of cement paste
B) To evaluate the Autoclave Expansion apparatus for cement paste testing
C) To assess the ability of cement paste to retain its volume and set within a specified time frame
D) To measure the flow rate of cement mortar using a Vicat needle
CORRECT ANSWER
C) To assess the ability of cement paste to retain its volume and set within a specified time frame
RATIONALE: Testing the soundness and setting characteristics of Portland Cement is crucial to evaluate its ability to
retain its volume and set within a specified time frame, as specified in ASTM C150. Options A and D are related but not
the primary purpose, while option B is a specific testing method rather than the overall purpose.
QUESTION 3
A candidate should identify that several fundamental attributes of Portland Cement Concrete (PCC),
such as durability and resistance to volume changes, are influenced by a variety of factors. Which of
the following contributes to these attributes?
A) The proportion of air-entraining admixtures in the mix design
B) The water/cement ratio and curing practices
C) The maximum size of fine aggregates used in the concrete
D) The ambient temperature during concrete placement
CORRECT ANSWER
B) The water/cement ratio and curing practices
RATIONALE: The water/cement ratio and curing practices play a critical role in determining the durability and resistance
to volume changes of Portland Cement Concrete (PCC). Adequate curing ensures the concrete develops the desired
properties, while an optimal water/cement ratio prevents excessive shrinkage and cracking. Options A, C, and D do not
directly impact these attributes.
QUESTION 4
Which of the following is a characteristic of efflorescence in portland cement concrete that is not
true?
A) The presence of soluble mineral salts within the concrete is a necessary condition.
Trusted by thousands of students and professionals worldwide Page 2 of 26
, B) Moisture plays a crucial role in dissolving these soluble salts.
C) Efflorescence is typically caused by a lack of sulfate in the concrete.
D) Efflorescence requires a combination of soluble salts and moisture.
CORRECT ANSWER
C) Efflorescence is typically caused by a lack of sulfate in the concrete.
RATIONALE: Efflorescence in portland cement concrete is caused by the presence of soluble mineral salts, moisture,
and degrees of sulfate. Option C is incorrect as it states a lack of sulfate is necessary for efflorescence, when in fact,
some degrees of sulfate are required.
QUESTION 5
What is the difference between the primary factors that influence the quality of portland cement
concrete (PCC)? A professional engineer should recognize that the quality of the paste is the most
critical factor compared to other parameters such as the water/cement (w/c) ratio and reinforcing
rebar.
A) The quality of the paste, water/cement (w/c) ratio, and reinforcing rebar are equally important.
B) The water/cement (w/c) ratio has a greater impact than the quality of the paste.
C) The quality of the paste is the most critical factor, followed by the water/cement (w/c) ratio.
D) The reinforcing rebar is the only factor that affects the quality of portland cement concrete (PCC).
CORRECT ANSWER
C) The quality of the paste is the most critical factor, followed by the water/cement (w/c) ratio.
RATIONALE: The quality of the paste determines the microstructure of the concrete, which significantly affects its
overall quality. While the water/cement (w/c) ratio and reinforcing rebar are important, they are secondary to the quality
of the paste.
QUESTION 6
Which of the following is an example of the primary mechanism responsible for the hardening and
gain of strength in Portland cement concrete?
A) Drying of the mix, caused by evaporation of excess water
B) Addition of salts to promote chemical reactions
C) Chemical interactions between water and portland cement
D) Mechanical compaction to remove air pockets
CORRECT ANSWER
C) Chemical interactions between water and portland cement
