Producing cement is a major source of carbon emissions — 8% of the global total. A company in Massachusetts has altered the recipe, finding a way to produce carbon-zero cement instead. Roughly 8% of ...

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 ...

Rome’s Pantheon stands defiant 2,000 years after it was built, its marble floors sheltered under the world’s largest unreinforced concrete dome. For decades, researchers have probed samples from Roman ...

Concrete is one of the world’s most commonly used materials, and unfortunately its production is a major source of carbon dioxide in the atmosphere. Now, engineers at Purdue University have developed ...

The only snag was that this didn’t match the recipe as described in historical texts. Now the same team is back with a fresh ...

Researchers at Tokyo University have developed a new technology that can turn any type of food waste into edible cement for construction use, with a tensile strength quadruple that of ordinary ...

Concrete and steel production are major sources of CO2 emissions, but a new solution from Cambridge could recycle both at the same time. Throwing old concrete into steel-processing furnaces not only ...

Cement is crucial for modern infrastructure, but its manufacturing process releases much carbon, contributing heavily to environmental concerns. So, how do we make cement greener? One promising answer ...

Isotopic analysis confirmed that the workers in Pompeii relied on hot-mixing when making their concrete. Samples from the ...

Concrete is the most widely used construction material, so developing ways to make it more durable can improve infrastructure ...

Road salt, used in copious helpings each winter to protect them from ice and preserve safe driving conditions, is slowly degrading the concrete they’re made of. Engineers have known for some time that ...
