2 .

What are building materials?

A)

Substance that is utilised in the construction of a structure

B)

Substance that is utilised in the manufacturing of construction materials

C)

Substance that which cannot be utilised in the construction of a structure

D)

None of the above

Correct Answer : Option (A) : Substance that is utilised in the construction of a structure

Explanation : The term “building material” refers to any substance that is utilised in the construction of a structure. Many naturally existing materials have been used to construct buildings, including clay, pebbles, sand, and wood, as well as twigs and leaves.

3 .

Which of the following is/are basic building materials?

A)

Brick

B)

Cement

C)

Wood

D)

All of the above

Correct Answer : Option (D) : All of the above

Explanation : The most basic types of building materials used in construction include wood, cement, aggregates, metals, bricks, concrete, and clay. These were chosen for their cost-effectiveness in construction projects.

4 .

In a mortar, the binding material is______

A)

sand

B)

cement

C)

cinder

D)

surkhi

Correct Answer : Option (B) : cement

Explanation : A mortar is a mixture of binding material, water, and fine aggregate (such as sand or surkhi). The binding material is typically cement, which is a powder made of a mixture of calcined limestone and clay. When mixed with water, cement forms a paste that hardens over time to bind the aggregate together and create a strong and durable building material. Sand and surkhi are both types of fine aggregate that are often used in mortars, and cinder is a type of coarse aggregate that is not typically used in mortars.

5 .

Ultimate strength to cement is provided by

A)

Tri-calcium aluminate

B)

Di-calcium silicate

C)

Tricalcium silicate

D)

Tetra calcium alumino ferrite.

Correct Answer : Option (B) : Di-calcium silicate

Explanation : Di-calcium Silicate (C2S) : This compound will undergo reaction slowly. It is responsible for the ultimate strength of concrete. This is also called as Belite. The heat of hydration is 260 J/Cal. Its proportion is 25 - 40%.

8 .

Why building materials are required?

A)

Building material signifies structural existence

B)

Building material signifies bonding between the construction materials

C)

Both (A) and (B)

D)

All of the above

Correct Answer : Option (A) : Building material signifies structural existence

Explanation : The existence of a structure is denoted by the material used to construct it. It displays the presence of aesthetic sense in a design and, as a result, determines the structure’s practicability. It aids in the establishment of a link between architectural visual quality and structural stability.
