1. Reinforced brick work is used in which of the following circumstances?
a) When the brick wall is to carry light loads
b) When the brick work has to bear some shear stress
c) When it is needed to decrease the longitudinal bond
d) When the brick work does not have to bear shear stresse
Explanation: Reinforced brick work is used in the circumstances when the brick work has to bear some shear stress, when it is needed to increase the longitudinal bond and when the brick wall is to carry and support heavy loads.
2. In stone composite masonry, ashlar masonry is used in backing of the wall while rubble masonry is used in the facing.
a) True
b) False
Explanation: Composite stone masonry is a combination of ashlar masonry and rubble masonry. Rubble masonry is composed of irregular shaped stones, while ashlar masonry consists of regular shaped stones and gives a smooth and pleasant appearance. Hence, rubble masonry is used in the backing of the wall while ashlar masonry is used in the facing.
3. Reinforced brick work uses __________
a) First class bricks with high compressive strength
b) First class bricks with moderate compressive strength
c) Second class bricks with high compressive strength
d) Second class bricks with moderate compressive strength
Explanation: Reinforced brick work is the one in which the resultant composite masonry is capable of bearing any kind of tensile or shear stresses in addition to the compressive stresses. Therefore, it uses first class bricks with high compressive strength in order to impart great strength to the resulting masonry.
4.Which of the following is a type of sheet metal which has been cut and stretched to form a diamond network?
a) Bricktor
b) Pier
c) Exmet
d) Hoop iron
Explanation: Steel meshed strips that are used in horizontal reinforcement are generally cut and stretched by a machine to form a diamond network. These strips are known as expanded metal or exmet.
5. In reinforced brick masonry, the reinforcement is laid only horizontally.
a) True
b) False
Explanation: In reinforced brick masonry, the reinforcement can be laid both horizontally or vertically. In horizontal reinforcement, bars are placed in such a way that they go all the way through the wall while in vertical reinforcement, vertical steel bars are placed at all the corners of the walls.
6. Which form of brick stone composite masonry is commonly used at locations where rubble stone is available in huge amounts, but ashlar is not available?
a) Brick-backed ashlar masonry
b) Brick-backed stone slab facing
c) Rubble-backed brick masonry
d) Stone-backed masonry
Explanation: Rubble-backed brick masonry is usually used at locations where rubble stone is available in huge amounts, but ashlar is not available. It uses rubble stones in large amounts. Rubble stones are rough and uneven
7. Which of the following tools is used for cutting soft bricks?
a) Scutch
b) Trowel
c) Jointer
d) Spirit level
Explanation: Scutch is a tool that is used for cutting soft bricks. A trowel is used for laying the mortar. A jointer is used for pointing the joints while the spirit level is used for levelling.
8. Mason’s square is used for checking __________ angles.
a) Acute
b) Obtuse
c) Right
d) Straight
Explanation: Mason’s square is widely used by builders and masons for checking right angles. It is one of the most important tools used for masonry work.
9. Which of the following is not a form of brick stone composite masonry?
a) Brick-backed ashlar masonry masonry
b) Brick-backed stone slab facing
c) Rubble-backed brick masonry
d) Stone-backed masonry
Explanation: Bricks and stones can be simultaneously used in three forms of composite masonry – brick-backed ashlar masonry, brick-backed stone slab facing and rubble-backed brick masonry. Hence, stone-backed masonry is not a form of brick stone composite masonry.
10. Plumb rule is used for checking the __________ of brick walls.
a) Horizontality
b) Angularity
c) Uniformity
d) Verticality
Explanation: Plumb rule is a tool that consists of a plumb line and a bob. It is extensively used by builders and surveyors for checking the verticality of the walls.
