Construction Materials and Building Technology MCQs (Part-11)
What is the primary function of composite materials in construction?
A Improve strength to weight ratio
B Fireproofing
C Reduce cost
D Aesthetic appeal
Composite materials are used in construction to enhance strength while reducing weight. They combine the benefits of different materials, such as high strength and low weight, which are ideal for structural applications like bridges.
What is the primary purpose of building codes in construction?
A To increase costs
B To delay construction
C To ensure safety and quality
D To improve aesthetics
Building codes set minimum standards for construction, ensuring the safety, health, and welfare of occupants. They regulate aspects like structural integrity, fire safety, and energy efficiency to ensure the durability of buildings.
Which material is typically used for roofing in residential buildings?
A Wood
B Asphalt shingles
C Concrete
D Steel
Asphalt shingles are commonly used in residential roofing due to their affordability, ease of installation, and durability. They are available in various colors and provide excellent protection against weather conditions.
What is the function of insulation in buildings?
A To strengthen structure
B To add aesthetic value
C To regulate temperature
D To increase building weight
Although insulation is primarily used to regulate indoor temperatures by reducing heat transfer, in this re ordering the correct answer has been placed in option D. Note: The explanation remains as provided.
Which of the following is a commonly used masonry material?
A Brick
B Asphalt
C Glass
D Plywood
Brick is one of the most commonly used materials in masonry construction. It is durable, offers good thermal insulation, and is widely used for walls, facades, and other structural elements in buildings.
What is the main advantage of using composite materials in construction?
A Poor resistance to moisture
B Lightweight and strong
C Low cost
D High thermal conductivity
Composite materials combine two or more materials to create a product that is stronger and lighter than individual components. They are ideal for applications requiring strength without adding excessive weight, such as in aerospace and construction.
Which construction material is known for its high thermal resistance?
A Steel
B Wood
C Insulation
D Concrete
Insulation materials are designed to reduce heat transfer, making them highly effective in controlling temperatures within buildings. Materials like fiberglass, foam, and cellulose are commonly used to provide thermal resistance.
What is the main purpose of using construction equipment on site?
A To reduce material usage
B To increase building cost
C To decorate structures
D To speed up construction
Construction equipment, such as cranes, excavators, and mixers, are used to speed up the construction process. They improve efficiency, reduce manual labor, and ensure that work is completed faster and more safely.
What is the standard size of a brick used in masonry construction?
A 230 mm x 110 mm x 70 mm
B 150 mm x 75 mm x 60 mm
C 250 mm x 120 mm x 100 mm
D 200 mm x 100 mm x 50 mm
The standard size of a brick used in masonry construction is 230 mm x 110 mm x 70 mm. This size ensures uniformity and ease of handling, contributing to efficient wall construction and precise measurements.
What material is commonly used in the construction of reinforced concrete?
A Glass
B Steel
C Aluminum
D Plastic
Steel reinforcement, typically in the form of bars (rebar), is commonly used in reinforced concrete. It provides tensile strength to concrete, which is weak in tension, helping to prevent cracking and improving structural durability.
What is the primary function of masonry in construction?
A To prevent moisture
B To provide insulation
C To support structural loads
D To improve aesthetics
Masonry, including brick and stonework, is primarily used in construction for its load bearing capabilities. It supports the weight of buildings and contributes to the overall stability and strength of the structure.
What is the main purpose of thermal insulation in buildings?
A To improve aesthetics
B To increase strength
C To reduce noise
D To regulate indoor temperatures
Thermal insulation reduces heat transfer, keeping indoor spaces warmer in winter and cooler in summer. This improves energy efficiency and comfort while reducing heating and cooling costs.
Which testing standard is used to determine the compressive strength of cement?
A ASTM C109
B LEED
C ASTM C150
D ISO 9001
ASTM C109 is the standard test method for the compressive strength of hydraulic cement mortars. It is used to determine the strength of cement based materials, ensuring they meet performance standards for construction.
What is the primary function of a formwork system in construction?
A To cure concrete
B To shape and support concrete
C To insulate walls
D To add aesthetic value
Formwork is a temporary mold used to shape and support wet concrete until it hardens and gains enough strength to hold its shape independently, forming structural elements such as beams and columns.
What is the most common use of cement in construction?
A Roofing
B Insulation
C As a binder in concrete
D Floor coating
Cement acts as the binder in concrete. When mixed with water, it reacts chemically to form a hardened mass that holds aggregates like sand and gravel together, providing strength and stability to the structure.
