Smart Concrete: Innovation in Construction

What are the three basic ingredients of concrete?

• Water, cement binder, and gravel

• Water, lime, and gravel

• Cement, sand, and steel

• Water, sand, and clay

What historical civilization is known for using concrete?

• Ancient Egyptians

• Ancient Romans

• Ancient Greeks

• Ancient Chinese

Who is Debra Cheung and what is her contribution to concrete research?

• A historian who studied ancient Roman concrete

• An engineer who developed a new method for pouring concrete

• A scientist who added carbon fibers to concrete to change its properties

• A construction worker who invented a new type of cement

How do carbon fibers affect the electrical properties of concrete?

• They make it more brittle

• They make it less conductive

• They have no effect on conductivity

• They make it more conductive and able to sense stress

What is the role of carbon fibers in smart concrete?

• To increase the weight of the concrete

• To enhance its color

• To improve its electrical conductivity

• To make it waterproof

What is the main advantage of smart concrete in construction?

• It is cheaper to produce

• It can detect stress and damage in real-time

• It is lighter than traditional concrete

• It requires less maintenance

What problem does smart concrete aim to solve in construction?

• Improving aesthetic appeal

• Increasing the speed of construction

• Monitoring structural integrity in real-time

• Reducing construction costs

What significant step did Debra Cheung take after her discovery?

• She abandoned the research

• She started a construction company

• She published a book on concrete

• She filed a patent for smart concrete

What is the potential impact of smart concrete on the construction industry?

• It will reduce the need for skilled labor

• It will enhance safety by early detection of stress

• It will allow for more innovative designs

• It will replace all traditional materials

What is the significance of the patent granted to Debra Cheung?

• It increases the cost of smart concrete

• It makes her the sole producer of concrete

• It protects her innovation and encourages further research

• It allows her to sell smart concrete worldwide
