QUESTIONS AND CORRECT RATIONALIZED
SOLUTIONS JUST RELEASED THIS YEAR
1. Which cement type is most commonly used for general concrete construction?
A) Type II
B) Type III
C) Type I
D) Type V
Answer: C
Type I Portland cement is the standard general-purpose cement used for most general-purpose
concrete work.
2. What effect does a lower water-cement ratio have on concrete?
A) Decreases strength
B) Increases permeability
C) Improves durability and strength
D) Causes segregation

Answer: C
Lower water-cement ratios produce denser, stronger, and more durable concrete.
3. What is the primary purpose of air-entraining admixtures?
A) Speed up setting
B) Improve freeze-thaw resistance
C) Increase color uniformity
D) Reduce cement usage
Answer: B
Air entrainment creates microscopic air bubbles that protect concrete from freeze-thaw
damage.
4. What does the term "slump" measure in fresh concrete?
A) Air content
B) Workability or consistency
C) Compressive strength
D) Aggregate size
Answer: B
Slump indicates how fluid or workable fresh concrete is.

5. Which component of concrete primarily provides compressive strength?
A) Water
B) Aggregate
C) Cement
D) Admixtures
Answer: C
Cement reacts chemically with water to form a hardened paste that binds aggregates together
and provides concrete's compressive strength.
6. Excessive water in a concrete mix most commonly leads to:
A) Higher strength
B) Faster curing
C) Reduced strength and durability
D) Improved finishability
Answer: C
Too much water increases porosity, weakening the hardened concrete.
7. Which aggregate size is typically used for standard slab-on-grade concrete?
A) Sand only

B) 3/4 inch coarse aggregate
C) 2 inch aggregate
D) Powdered limestone
Answer: B
3/4 inch aggregate balances strength, workability, and finishability.
8. Which test is commonly used to determine concrete compressive strength?
A) Slump test
B) Air content test
C) Cylinder compression test
D) Penetration resistance test
Answer: C
Cylinders are cast and tested in compression to determine concrete strength.
9. What is the typical maximum recommended slump for floor slabs?
A) 1 inch
B) 2 inches
C) 4 inches
D) 7 inches
