1. Which of the following is the most important characteristic of the alumina in the brick earth?
A. Maintain plasticity
B. Increase strength of bricks
C. To manufacture impermeable bricks
D. Reduce wrapping when heated
Answer ||| A
Solution ||| It is the principal constituent of every kind of brick earth. It imparts plasticity to the brick earth which is essential for proper moulding of bricks.
2. The standard size of a masonry brick is:
A. 19cm x 9cm x 9cm
B. 18cm x 9cm x 9cm
C. 18cm x 8cm x 8cm
D. 19cm x 8cm x 8cm
Answer ||| A
Solution ||| The Nominal size of Brick is 20cm X 10cm X 10cm.
The Standard size or actual size of brick is 19cm X 9cm X 9cm.
3. Which of the following is good for making the bricks?
A. Silted soil
B. weathered clay
C. Soil
D. None of these
Answer ||| B
Solution ||| The cleaned clay is exposed to atmosphere for softening. The period of weathering may be 3 to 4 weeks or a full rainy season. Generally, the clay is dug out just before the rainy season for larger projects. In contrast to colour of stained body, brick colour is permanent and will not be faded during weathering process
4. A brick masonry could fail due to _______.
A. Rupture along a vertical joint in poorly bonded walls
B. Shearing along a horizontal plane
C. Crushing due to overloading
D. Any of these
Answer ||| D
Solution ||| All the are correct. Brick masonry weak about poorly bonded vertical joints, shearing along horizontal plane, and some time crushed by over loading
5.Statement (I): Sand containing 50-60% silica is not fit for making bricks.
Statement (II): High silica content in sand makes the brick brittle.
A. Both Statement (I) and Statement (II) are individually true and Statement (II) is the correct explanation of Statement (I)
B. Both Statement (I) and Statement (II) are individually true but Statement (II) is not the correct explanation of Statement (I)
C. Statement (I) is true but Statement (II) is false
D. Statement (I) is false but Statement (II) is true
Answer ||| D
Solution |||
Silica provides bulk, shape and size to the brick. It prevents the shrinkage of the brick on drying but excess of it leads to brittleness in the brick because of less cohesion. Right amount of silica in sand for brick – 50-60%
6.Assertion [A]: Filed test are used to find colour, strength and fineness of cement
Reason[R]: Testing of cement is necessary before starting of construction.
A. A is correct, R is correct and R is correct explanation of A
B. A is correct, R is correct and R is not a correct explanation of A
C. A is correct, R is incorrect
D. A is incorrect, R is correct
Answer ||| D
Solution ||| Fineness can be find out using fineness test which is a lab test
7.Assertion [A] : Sieve method , Sedimentation method , Air permeability method are fineness test
Reason[R]: Sedimentation test and Air permeability test measures surface area while sieve test measures grain size.
A. A is correct, R is correct and R is correct explanation of A
B. A is correct, R is correct and R is not a correct explanation of A
C. A is correct, R is incorrect
D. A is incorrect, R is correct
Answer ||| A
Solution ||| Fineness can be measured by 3 method
- Sedimentation test
- Sieve method
- Air permeability test
Sedimentation test and Air permeability test measures surface are while sieve test measures grain size.
Correct reason will be Principal of test
Example : Sieve method is fineness test because Using sieve test we distributed particles of cement based on their grain size.
8.Assertion [A] : Large size cube are not made to find compressive strength of cement.
Reason[R]: Cement can shrink and cracks can develope.
A. A is correct, R is correct and R is correct explanation of A
B. A is correct, R is correct and R is not a correct explanation of A
C. A is correct, R is incorrect
D. A is incorrect, R is correct
Answer ||| A
Solution ||| Large size cube is not made to find compressive strength of cement because cement can shrink and cracks can develop.
9.Match the following
A. P – iii , Q- i, R- ii
B. P – i, Q –ii, R- iii
C. P- iii , Q – ii , R- i
D. P – ii ,Q –iii ,R – i
Answer ||| A
10.Which of the following statement is not correct in relation with cement?
A. To find initial setting time cement paste is made of consistency 0.80 P
B. Initial setting time test is completed, when needle penetrates 5 to 7 mm from bottom.
C. Initial setting time is 30 min for OPC and 1 hr for low heat cement
D. One of the reasons to do an initial setting time test is to find time available for cement to reach from plant to site.
Answer ||| A
Solution |||
- To find the initial setting time cement paste is made of consistency 0.85 P.
- The initial setting time test is completed, when the needle penetrates 5 to 7 mm from the bottom.
- An initial setting time is 30 min for OPC and 1 hr. for low-heat cement.
- The initial setting time test is to find time available for cement to reach from plant to site.
11.For lime concrete, ________
A. slump is 0 to 70 mm
B. flexural strength at 90 days is 0.2 N/mm2
C. compressive strength at 90 days is 1.5 N/mm2
D. All options are correct
Answer ||| D
Solution ||| It is a concrete made from a mixture of lime, sand, and gravel is said to be as lime concrete. It was widely used before the lime was replaced by Portland cement.
Hence all the above options is correct.
12.The main constituent which impart hydraulicity to hydraulic lime is:
A. Calcium oxide
B. Silica
C. Clay
D. Water
Answer ||| C
Solution ||| Clay is mainly responsible for the hydraulic properties of lime. The percentage of clay to produce hydraulicity in lime stone usually varies from 10 to 30 %. When clay is present as 20-30 percent of lime, it exhibit excellent hydraulic properties and is most suitable for aqueous foundation.
13.Quick lime is:
A. Calcium carbonate
B. Calcium oxide
C. Calcium hydroxide
D. None of these
Answer ||| B
Solution ||| The lime which is obtained by the calcination of comparatively pure limestone is known as the quick lime or caustic lime. It is capable of slaking with water and has no affinity for carbonic acid. Its chemical composition is CaO (calcium oxide).
14.Surkhi is added to lime mortar to:
A. Prevent shrinkage
B. Decrease setting time
C. Increase bulk
D. Impart hydraulicity
Answer ||| D
Solution ||| Surkhi (Powdered broken brick) is used as an adulterant but it imparts strength and hydraulic properties to the mortar. To develop more strength, it should be ground very finely with lime in the mortar grinding mill.
15.The process of adding water to lime to convert it into a hydrated lime is termed as:-
A. Watering
B. baking
C. hydration
D. Slaking
Answer ||| D
Solution ||| Shaking is a phenomenon in which lime is added to water to convert it into a hydrated line.
