Snow-melting future concrete: Special mix could de-ice itself with electric current

The video discusses conductive concrete, a mixture of steel shavings and carbon particles, which conducts electricity and generates heat when connected to a power source. This heat is sufficient to melt snow and ice, making it energy-efficient as it requires only 22% of the energy needed to light an incandescent bulb. Although conductive concrete is more expensive at $300 per cubic yard compared to $120 for normal concrete, its high upfront cost can be offset by reduced maintenance and de-icing expenses.

What materials are added to concrete to make it conductive?

• Steel shavings and carbon particles

• Copper wires and silicon

• Aluminum foil and graphite

• Iron filings and plastic

How does conductive concrete generate heat?

• By absorbing sunlight

• Through friction

• Through chemical reactions

• By conducting electricity

What percentage of energy is required to heat 1 square foot of conductive concrete compared to lighting an incandescent bulb?

• 50%

• 22%

• 10%

• 75%

What is the cost per cubic yard of normal concrete?

• $120

• $200

• $300

• $150

Why might the higher initial cost of conductive concrete be justified?

• It is more aesthetically pleasing

• It reduces long-term maintenance and de-icing costs

• It is easier to install

• It is lighter in weight
