Engineers invented bendable concrete that’s self-healing and self-heating

Concrete is a cornerstone of modern construction, but its inherent flaws pose significant challenges for construction companies—and environmentalists alike. Now, though, engineers have developed a new type of concrete that can bend under pressure, heat itself, and even repair its own cracks. This bendable concrete could drastically improve durability and reduce maintenance costs.

Traditional concrete is rigid and brittle. Over time, mechanical stress and temperature changes lead to cracks...
