The billions of tons of cement made each year have an enormous carbon footprint: 8% of global emissions, or four times more than the airline industry. That’s both because of the energy used to make ...

After a decade in the works, researchers at University of California, Los Angeles, have successfully devised a way to produce cement with 98% less CO2 emissions than traditional methods. The UCLA team ...

Cement production is responsible for around 8% of global carbon emissions. Using microalgae to make a key ingredient could drastically cut that carbon footprint. During a trip to Thailand on his ...

Recycled glass can be converted into a pozzolan in concrete that’s not only more sustainable and durable than traditional concrete, but reduces the urban heat-island effect because of its white color.

Excavations of an ancient construction site in Pompeii have revealed the process of how Romans mixed their self-healing concrete.

One of the biggest problems in dealing with carbon dioxide emissions is the making of the key component of cement: lime (calcium oxide). Now, a small company with the cute name Sublime Systems appears ...

It’s a major contributor to climate change — the way buildings and roads are made with concrete. It’s also a problem that’s growing as more of the world develops. So the race has been on to find ...

Chemists at Stanford University have developed a low-cost way to remove carbon dioxide (CO) from the atmosphere using an ...

As winter approaches, Canada's roads, bridges, sidewalks and buildings are facing a familiar problem: cracks caused by large temperature swings. These cracks weaken infrastructure and cost millions to ...

A photobioreactor, which looks like a large vat of blue liquid with pink light shining, at Prometheus Materials. Stimulated by light, microbes in this bioreactor multiply and react carbon dioxide with ...

In a move that could accelerate the transition to "green concrete," two of the world's major cement producers are investing $75 million in Sublime Systems, a low-carbon cement startup. According to ...
