EXAMINATION INSTRUCTIONS
This practice examination is designed to assess knowledge of concrete materials, mixing,
placement, finishing, and reinforcement fundamentals. Each question has one correct answer.
Rationales are based on standard concrete finishing practices, ACI principles, and industry-
accepted construction methods.
EXAM COVERAGE
• Concrete materials and mix components
• Workability, slump, and water–cement ratio
• Aggregate selection
• Reinforcement purpose and placement
• Concrete placement and finishing tools
• Bleeding, curing, and surface quality
PRACTICE EXAM QUESTIONS
Question 1
,Page 2 of 87
What is the primary purpose of adding water to a concrete mix?
A) Increase aggregate strength
B) Improve workability and initiate hydration ✅
C) Reduce cement content
D) Speed up curing
Rationale:
Water is essential to initiate the hydration reaction with cement and to improve workability so
concrete can be placed, consolidated, and finished properly.
Question 2
Which component of concrete primarily provides strength?
A) Water
B) Aggregate
C) Cement ✅
D) Admixtures
Rationale:
Cement reacts chemically with water to form a hardened paste that binds aggregates together
and provides concrete’s compressive strength.

Question 3
What does the term “slump” measure?
A) Air content
B) Concrete temperature
C) Workability or consistency ✅
D) Compressive strength
Rationale:
Slump measures the consistency and flowability of fresh concrete, indicating how easily it can
be placed and finished.
Question 4
Excessive water in a concrete mix most commonly leads to:
A) Higher strength
B) Faster curing
C) Reduced strength and durability ✅
D) Improved finishability
Rationale:
Too much water increases porosity, reduces density, and weakens hardened concrete, leading
to reduced strength and long-term durability issues.

Question 5
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
Rationale:
3/4-inch aggregate provides a good balance of strength, workability, and finishability for slab-
on-grade applications.
Question 6
What is the main purpose of reinforcement in concrete?
A) Increase compressive strength
B) Improve color
C) Control cracking and improve tensile strength ✅
D) Reduce curing time
