UPDATE) FROM REAL PAST PAPERS QUESTIONS – SET
100 MOST COMMON EXAM FREQUENTLY TESTED
QUESTIONS AND ANSWERS IN DETAILS 100% VERIFIED
EXAM HIGHLY RECOMMENDABLE FOR GRADE A+
1. A technician is performing a sieve analysis on a fine aggregate sample. What
is the primary purpose of this test
A. Determine moisture content
B. Determine particle size distribution
C. Measure density
D. Evaluate specific gravity
✔ Correct Answer: B (Determine particle size distribution)
The sieve analysis test is specifically used to evaluate the gradation or
distribution of particle sizes within an aggregate sample, which is critical
for mix design and quality control.
2. During a Proctor compaction test, what is being determined
A. Optimum cement content
B. Maximum dry density and optimum moisture content
C. Aggregate absorption rate
D. Soil permeability
✔ Correct Answer: B (Maximum dry density and optimum moisture
content)
The Proctor test identifies the relationship between moisture content and
dry density to determine the optimum conditions for compaction.
3. A slump test result of 0 inches indicates what about the concrete
A. High workability
, B. Medium workability
C. No workability
D. Excessive water content
✔ Correct Answer: C (No workability)
A zero slump indicates extremely stiff concrete with no measurable flow,
often used in pavement or roller-compacted applications.
4. What is the standard curing time before testing compressive strength of
concrete cylinders
A. 3 days
B. 7 days
C. 14 days
D. 28 days
✔ Correct Answer: D (28 days)
Concrete compressive strength is typically evaluated at 28 days, which is
considered the standard reference age for design strength.
5. In asphalt testing, what does Marshall Stability measure
A. Temperature resistance
B. Load-bearing capacity
C. Binder content
D. Air void content
✔ Correct Answer: B (Load-bearing capacity)
Marshall Stability assesses the maximum load the asphalt specimen can
withstand before failure, indicating its strength.
6. A soil sample has a high plasticity index. What does this indicate
A. Low compressibility
B. High clay content
C. High permeability
D. Low cohesion
✔ Correct Answer: B (High clay content)
A high plasticity index reflects significant clay content, leading to greater
plasticity and deformation potential.
, 7. What is the purpose of air entrainment in concrete
A. Increase density
B. Improve freeze-thaw resistance
C. Reduce curing time
D. Increase compressive strength
✔ Correct Answer: B (Improve freeze-thaw resistance)
Air entrainment introduces microscopic air bubbles that protect concrete
from damage due to freezing and thawing cycles.
8. A technician records incorrect weights during aggregate testing. What is the
most likely impact
A. No effect
B. Increased accuracy
C. Invalid test results
D. Improved consistency
✔ Correct Answer: C (Invalid test results)
Accurate measurements are critical; incorrect weights directly
compromise the validity of test results.
9. What does specific gravity of aggregate indicate
A. Shape of particles
B. Strength of aggregate
C. Density relative to water
D. Moisture content
✔ Correct Answer: C (Density relative to water)
Specific gravity compares the density of aggregate to water, influencing
mix proportions and performance.
10.In concrete testing, what does a high water-cement ratio typically cause
A. Increased strength
B. Reduced durability
C. Faster curing
D. Lower permeability
✔ Correct Answer: B (Reduced durability)
