2026 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 field technician is asked to determine the moisture content of a soil
sample using the oven-drying method. What is the standard temperature
range for drying?
A. 60–80°C
B. 90–100°C
C. 105–110°C
D. 120–140°C
✔ Correct Answer: C (105–110°C)
The standard oven-drying temperature ensures complete moisture
removal without altering soil properties, making 105–110°C the accepted
ASTM range.
2. Which test is primarily used to determine the consistency limits of fine-
grained soils?
A. Proctor Compaction Test
B. Atterberg Limits Test
C. Sieve Analysis
D. Hydrometer Analysis
✔ Correct Answer: B (Atterberg Limits Test)
The Atterberg Limits test defines liquid, plastic, and shrinkage limits,
which classify soil consistency and behavior.
,3. A concrete slump test measures which property of fresh concrete?
A. Air content
B. Workability
C. Strength
D. Density
✔ Correct Answer: B (Workability)
Slump indicates the ease of placement and flow of concrete, which is
defined as workability.
4. In sieve analysis, what is the purpose of the No. 200 sieve?
A. Separate coarse aggregates
B. Determine gravel content
C. Measure fine particles
D. Remove organic matter
✔ Correct Answer: C (Measure fine particles)
The No. 200 sieve identifies fines passing 0.075 mm, critical for soil
classification.
5. A technician records incorrect weights due to an uncalibrated balance.
What is the primary issue?
A. Precision error
B. Human error
C. Systematic error
D. Random error
✔ Correct Answer: C (Systematic error)
Calibration issues cause consistent bias in measurements, classified as
systematic error.
6. What is the unit weight of water typically used in calculations?
A. 9.81 kN/m³
B. 10 kN/m³
C. 62.4 lb/ft³
D. Both A and C
✔ Correct Answer: D (Both A and C)
, Both metric and imperial values are standard references for water unit
weight.
7. A sample is described as poorly graded sand. What does this indicate?
A. Wide range of particle sizes
B. Uniform particle size
C. High clay content
D. High moisture content
✔ Correct Answer: B (Uniform particle size)
Poorly graded soils lack a variety of sizes, meaning particles are mostly
uniform.
8. Which test determines the maximum dry density and optimum moisture
content?
A. CBR Test
B. Proctor Test
C. Slump Test
D. Permeability Test
✔ Correct Answer: B (Proctor Test)
The Proctor test establishes compaction characteristics essential for
construction.
9. A slump of zero indicates what type of concrete?
A. Highly workable
B. Flowable
C. Very stiff
D. Segregated
✔ Correct Answer: C (Very stiff)
Zero slump means the concrete has almost no flow, indicating stiffness.
10.What is the main purpose of curing concrete?
A. Increase weight
B. Prevent cracking
C. Maintain moisture for hydration
