Ancient Roman Concrete Was Inspired By Volcanic Chemistry Ancient Roman Concrete Was Inspired By Volcanic Chemistry

In 1982, the ground beneath the historic port city of Pozzuoli began to rise like a cake in the oven. Within two years, the swell had exceeded 6 feet. Then the earth started shaking—first, a swarm of microquakes. When the first magnitude 4 quake hit, Pozzuoli became a ghost town overnight.

A Failed Lab Experiment Accidentally Invented a Replacement For Cement A Failed Lab Experiment Accidentally Invented a Replacement For Cement

As the world’s cities expand at faster and faster speeds, so does its use of cement. One oft-quoted statistic shows that China alone used as much cement in the last three years as the US used in the last 100. Just one problem: Cement is responsible for pushing a hell of a lot of carbon dioxide into the world.

A New Material Uses the Cold Darkness of Outer Space To Cool Your House A New Material Uses the Cold Darkness of Outer Space To Cool Your House

In today's awesomely brutal-sounding material science news, Stanford engineers have created a building material that exploits that "cold darkness of the Universe" to cool itself—even when the sun is shining. Stanford calls it a "cosmic fridge," and it could replace air conditioning.

The Lattice of Tubes Covering This Building Are a Natural AC System The Lattice of Tubes Covering This Building Are a Natural AC System

If you have ever sweated through a summer in the city, you can thank those skyscrapers all around. Tall buildings trap heat that create urban heat islands. But what if you could create a building that cools the city instead? A building skin made of a series of tubes with evaporating rainwater can do just that.

Waste ash can be recycled into super-strong concrete Waste ash can be recycled into super-strong concrete

Coating concrete with residual ash from burning coal can make it strong enough to withstand hellish conditions — and save governments millions of dollars. Fly ash is an industrial byproduct from coal power plants, which used to be pumped into the atmosphere, but is now collected.

10 Houses Built From Unlikely Materials 10 Houses Built From Unlikely Materials

James May's Lego abode may be shaping up to be spectacular, but he's far from the first person to build a house out of something novel. Here are ten more amazing homes with, shall we say, unorthodox constituents.

Self-Mending Concrete Bends Like Rubber, Heals Like Flesh Self-Mending Concrete Bends Like Rubber, Heals Like Flesh

It can be bent into a U-shape, "heals" cracks with nothing more than rainwater, and is strong enough to build bridges from. Is Victor Li's composite building material really even concrete anymore?
