Our world is built of concrete. Durable and cheap, it’s the construction material of choice for buildings, bridges and tunnels. But its ubiquity means it has a huge environmental impact. Concrete is ...

This strange white paste might not look like much, but it might help solve the sand shortage, while making the cement manufacturing process capture carbon dioxide instead of emitting it. Scientists at ...

In 2014, hundreds of Angelenos gathered downtown to watch more than 2,000 trucks pour concrete into a vast hole. During that event, Los Angeles set a world record: 80 million pounds of concrete were ...

Masoud Akbarzadeh (left), a professor of architecture at the University of Pennsylvania, is working with students to design concrete structures that use as little concrete as possible while remaining ...

To make concrete, minerals need to be crushed and cooked in a kiln heated to temperatures above 2,600 °F (1,427 °C) to produce a material known as klinker. The chemical processes involved in the ...

Scientists have created hollow concrete that is 5.6 times stronger than regular concrete. The new design is based on the human femur, which features a honeycomb-like design, making it more resilient ...

Using seawater, electricity and carbon dioxide (CO 2), Northwestern University scientists have developed a new carbon-negative building material. As Earth’s climate continues to warm, researchers ...

To make aerated concrete, add a foam-forming agent and stir in a significant amount of air. This serves to make the concrete significantly lighter, better insulating, and more resilient to fire.
