What is graphene?

• A) A type of steel used in construction

• B) A two-dimensional material with unique properties

• C) A type of glass used in windows

• D) A new form of concrete

What is one of the key properties of graphene?

• Heavier than steel

• Poor electrical conductivity

• More conductive than copper

• Brittle and fragile

How does 3D-printed bioplastic help the construction industry?

• It increases waste production

• It reduces environmental impact by using renewable materials

• It replaces the need for steel structures

• It is only used for decorative purposes

What is a key benefit of Alusion panels (architectural stabilised aluminium foam)?

• They generate electricity

• They are 100% recyclable and non-combustible

• They are only used for interior design

• They dissolve in water

What is the main purpose of ventilated building materials?

• To increase building weight

• To improve air circulation and thermal efficiency

• To block all airflow in buildings

• To replace traditional brick materials

What is a key characteristic of breathing walls?

• They completely seal off airflow

• They contain porous materials that allow air to flow through

• They require electrical power to function

• They are only used in skyscrapers

How does a breathable façade control temperature?

• By using air conditioning units

• By contracting and expanding using flexible engineered ribbons

• By blocking all sunlight

• By reflecting heat using mirrors

What is a liquid roof coating?

• A waterproof membrane applied to roofs

• A new type of tile material

• A method of insulating floors

• A self-healing material

Why is transparent aluminium a promising material for construction?

• It is lightweight and biodegradable

• It can be used in large glass structures and withstands harsh conditions

• It replaces all types of steel in construction

• It is the cheapest material available

What is the purpose of self-healing concrete?

• To allow buildings to expand over time

• To repair cracks and reduce maintenance costs

• To make roads more flexible

• To eliminate the need for bridges
