Construction Materials and Building Technology MCQs (Part-4)
Which of the following is a property of good quality bricks?
A Low compressive strength
B High water absorption
C Uniform shape and size
D Irregular texture
Good quality bricks should have a uniform shape and size to ensure proper alignment and bonding in masonry construction. They should also have high compressive strength, low water absorption, and a smooth texture for durability and aesthetic appeal.
What is the primary function of aggregates in concrete?
A Provide binding
B Reduce cost
C Increase strength and volume
D Improve aesthetics
Aggregates, such as sand and gravel, make up 60-75% of concrete volume. They provide bulk, reduce shrinkage, and enhance the strength and durability of the concrete mix.
Which of the following is a natural building stone?
A Concrete
B Granite
C Brick
D Gypsum
Granite is a natural building stone known for its strength, durability, and aesthetic appeal. It is commonly used in construction for countertops, flooring, and exterior cladding.
What is the main purpose of curing concrete?
A To dry it quickly
B To maintain moisture for hydration
C To reduce its strength
D To increase its cost
Curing is the process of maintaining adequate moisture, temperature, and time to allow the concrete to achieve its desired strength and durability through proper hydration of cement.
Which of the following is a composite material?
A Steel
B Concrete
C Timber
D Brick
Concrete is a composite material made up of cement, aggregates, and water. The combination of these materials results in a strong and durable construction material.
What is the primary use of gypsum in construction?
A Reinforcement
B Waterproofing
C Plastering
D Insulation
Gypsum is widely used in construction for plastering walls and ceilings. It provides a smooth finish, is fire-resistant, and has good thermal and acoustic properties.
Which of the following is a fireproofing material?
A Wood
B Asbestos
C PVC
D Glass wool
Glass wool is a fireproofing material made from fine glass fibers. It is used for insulation and fire protection due to its non-combustible nature and ability to withstand high temperatures.
What is the main advantage of using recycled materials in construction?
A Increased cost
B Reduced environmental impact
C Lower strength
D Poor durability
Using recycled materials in construction reduces waste, conserves natural resources, and minimizes the environmental impact of building activities. It also promotes sustainability and cost-effectiveness.
Which of the following is a roofing material?
A Concrete
B Asphalt shingles
C Brick
D Gypsum
Asphalt shingles are a common roofing material due to their affordability, durability, and ease of installation. They provide effective protection against weather elements.
What is the primary purpose of building codes?
A Increase construction cost
B Ensure safety and quality
C Delay construction projects
D Reduce material usage
Building codes are regulations that set minimum standards for construction to ensure the safety, health, and welfare of occupants. They cover aspects like structural integrity, fire safety, and accessibility.
Which of the following is a lightweight aggregate?
A Gravel
B Pumice
C Sand
D Crushed stone
Pumice is a lightweight volcanic rock used as an aggregate in concrete. It reduces the overall weight of the structure while providing good insulation and durability.
What is the main purpose of reinforcement detailing?
A To increase cost
B To ensure proper placement of steel bars
C To reduce concrete strength
D To delay construction
Reinforcement detailing involves specifying the size, spacing, and placement of steel bars in concrete structures. It ensures structural integrity and prevents failure under load.
Which of the following is a sustainable construction practice?
A Using non-renewable materials
B Minimizing waste
C Increasing energy consumption
D Ignoring environmental impact
Sustainable construction practices focus on minimizing waste, using renewable materials, and reducing energy consumption to lower the environmental impact of building activities.
What is the primary function of insulation in buildings?
A Increase heat transfer
B Reduce energy efficiency
C Control temperature
D Increase noise
Insulation materials reduce heat transfer, helping to maintain a comfortable indoor temperature. This improves energy efficiency and reduces heating and cooling costs.
Which of the following is a testing standard for construction materials?
A ISO 9001
B ASTM C109
C OSHA
D LEED
ASTM C109 is a standard test method for compressive strength of hydraulic cement mortars. It ensures the quality and performance of cement-based materials in construction.
