MICHIGAN CONCRETE CONTRACTOR LICENSE EXAM 2025/2026 – 200 Practice
Questions with Answers & EXPERT RATIONALE
QUESTION 1
What is the minimum compressive strength of concrete typically required for
residential foundations in Michigan?
A) 2,000 psi
B) 2,500 psi
C) 3,000 psi
D) 3,500 psi
E) 4,000 psi
C) 3,000 psi
EXPERT RATIONALE: Michigan building codes and ACI 318 standards require a
minimum compressive strength of 3,000 psi for residential foundation concrete to
ensure structural integrity under typical load and freeze-thaw conditions.
,QUESTION 2
What does the water-cement (w/c) ratio primarily affect in a concrete mix?
A) Color of the finished surface
B) Workability only
C) Strength and durability
D) Aggregate size selection
E) Curing time exclusively
C) Strength and durability
EXPERT RATIONALE: The water-cement ratio is the most critical factor determining
concrete strength and durability. A lower w/c ratio produces stronger, more durable
concrete, while a higher ratio weakens the mix and increases permeability.
QUESTION 3
Which of the following is the standard slump range for concrete used in
flatwork such as driveways and sidewalks?
A) 0–1 inch
B) 1–2 inches
C) 3–5 inches
D) 6–7 inches
E) 8–9 inches
C) 3–5 inches
EXPERT RATIONALE: For flatwork applications like driveways and sidewalks, a slump of
3–5 inches is standard. This range provides adequate workability for placement while
maintaining sufficient strength after curing.
,QUESTION 4
In Michigan, what is the maximum air entrainment percentage recommended
for concrete exposed to severe freeze-thaw conditions?
A) 2%
B) 4%
C) 5%
D) 7%
E) 9%
D) 7%
EXPERT RATIONALE: For severe freeze-thaw exposure in Michigan's climate, ACI 318 and
Michigan guidelines recommend air entrainment of 6–7% for concrete with smaller
aggregate. This protects against freeze-thaw damage by allowing water to expand into
air voids.
QUESTION 5
What type of cement is most commonly used for general concrete
construction in Michigan?
A) Type II cement
B) Type III cement
C) Type IV cement
D) Type I/II cement
E) Type V cement
D) Type I/II cement
EXPERT RATIONALE: Type I/II Portland cement is the most commonly used general-
purpose cement. It satisfies both standard construction requirements and offers
, moderate sulfate resistance, making it suitable for Michigan's soil and climate
conditions.
QUESTION 6
What is the purpose of control joints in concrete flatwork?
A) To add decorative lines to the surface
B) To allow electrical conduit passage
C) To control cracking by creating weak planes
D) To improve drainage across the slab
E) To increase the load-bearing capacity
C) To control cracking by creating weak planes
EXPERT RATIONALE: Control joints are intentional weakened planes tooled or cut into
concrete to direct cracking. As concrete shrinks during curing, it cracks at these joints
rather than randomly across the surface.
QUESTION 7
How deep should control joints be cut relative to the slab thickness?
A) 1/8 of the slab depth
B) 1/6 of the slab depth
C) 1/4 of the slab depth
D) 1/2 of the slab depth
E) Full depth of the slab
C) 1/4 of the slab depth
