NEW VERSION!!
1. Which tool is used to smooth and compact the surface of freshly placed
concrete?
A. Edger
B. Float
C. Screed
D. Trowel
D. Trowel A trowel provides a smooth, dense finish after floating.
2. What causes concrete to segregate during placement?
A. Proper vibration
B. Low slump mix
C. Excessive free fall
D. Use of admixtures
C. Excessive free fall Dropping concrete from heights separates aggregate
from paste.
3. The purpose of control joints in slabs is to:
A. Strengthen the slab
B. Prevent cracking
C. Reduce finishing time
D. Increase load capacity
, B. Prevent cracking They manage shrinkage cracking by guiding where
cracks form.
4. Bleed water appears when:
A. Concrete is over-vibrated
B. Water rises to the surface during settlement
C. Concrete is too dry
D. Using air-entrained concrete
B. Water rises to the surface during settlement Bleeding is normal but
excessive bleeding weakens the surface.
5. Air entrainment in concrete helps:
A. Improve steel bonding
B. Improve freeze-thaw durability
C. Increase slump loss
D. Reduce workability
B. Improve freeze-thaw durability Air voids relieve internal pressure from
ice expansion.
6. A bull float is used:
A. Before screeding
B. After final troweling
C. Immediately after screeding
D. After curing
C. Immediately after screeding It smooths and embeds aggregate before
bleed water evaporates.
7. High-slump concrete is:
A. Stiff
B. Very workable
C. Difficult to pump
D. Not allowed
B. Very workable Slump measures workability.
, 8. The most common cause of surface scaling is:
A. Low humidity
B. Inadequate curing
C. Too many admixtures
D. Proper consolidation
B. Inadequate curing Poor curing weakens the top layer leading to scaling.
9. A magnesium hand float is preferred because it:
A. Seals surface early
B. Pulls water to surface
C. Gives non-slip texture
D. Avoids trapping water
D. Avoids trapping water Magnesium helps keep the surface open, not
sealed too early.
10.When should final troweling occur?
A. While bleed water is present
B. After bleed water is gone
C. Before floating
D. During curing
B. After bleed water is gone Finishing over bleed water causes
delamination.
11.Which finish is commonly used for exterior sidewalks?
A. Steel-trowel finish
B. Broom finish
C. Burnished finish
D. Polished finish
B. Broom finish Provides slip resistance.
12.Concrete curing primarily ensures:
A. Faster set
B. Strength gain
