New design approach may help slash the price of ultra-durable concrete

Concrete, although the most common building material in the world, is brittle and can easily crack under tension. Ultra-high-performance concrete (UHPC) is a special class of concrete known for its dense structure and extreme durability. This class uses internal metallic fibers to flex and resist cracking—the downside being these fibers can lead the material to cost up to 30 times more than traditional concrete.
