Phase-Change Concrete Demonstrates Snow-Melting Capabilities in Real-World Tests

Researchers at Drexel University have developed a self-heating concrete that melts snow and ice without the need for salt or shovels, potentially reducing road maintenance costs and environmental impact.

A new study by Drexel University showcases a self-heating concrete that can melt snow and ice for up to 10 hours, offering a sustainable alternative to traditional snow removal methods.
The concrete incorporates paraffin, a phase-change material, which releases heat as temperatures drop, preventing the surface from freezing and reducing the need for salting and plowing.
In real-world tests, phase-change concrete slabs maintained surface temperatures between 42°F and 55°F, effectively melting snow and ice without additional heating systems.
Researchers highlight the potential for this technology to preserve the integrity of road surfaces, lower maintenance costs, and mitigate environmental damage from salt use.
The study also notes limitations, such as reduced effectiveness in heavy snowfall and the need for the material to 'recharge' between snow events, indicating areas for future improvement.
