New recipe makes concrete that absorbs more CO2 than it emits

Concrete is one of the most common materials on Earth, thanks to its high strength and low cost – but it’s also one of the largest single sources of carbon dioxide emissions. Engineers at Washington State University (WSU) have developed a new method fo… Continue reading New recipe makes concrete that absorbs more CO2 than it emits

An inexpensive ingredient may reduce concrete’s climate impact

After water, concrete is the world’s most consumed material and is the mainstay of construction everywhere, and concrete production’s impact on the environment is significant. Researchers have discovered that introducing an inexpensive, readily availab… Continue reading An inexpensive ingredient may reduce concrete’s climate impact

Secret ingredient found to help ancient Roman concrete self-heal

Neglect a modern concrete structure for a few decades and it’ll start to fall apart – and yet, structures built by the ancient Romans are still standing strong after 2,000 years. Now, engineers have found an inclusion that helps ancient concrete self-h… Continue reading Secret ingredient found to help ancient Roman concrete self-heal

Shredded masks and broken glass: Green ingredients for better concrete

From residential homes and skyscrapers to art sculptures and footpaths, concrete is everywhere you look and it’s difficult to imagine the modern world without it. As the most widely-used human-made material on Earth, it also plays a huge role in global… Continue reading Shredded masks and broken glass: Green ingredients for better concrete

Material obtained from shrimp shells makes for stronger cement

The production of cement is a major source of carbon emissions, so the less of it that’s used, the better. A new study could help, as it shows that cement can be made much stronger with the addition of material derived from waste shrimp shells.Continue… Continue reading Material obtained from shrimp shells makes for stronger cement

Cement formed with biogenic limestone promises carbon-neutral concrete

Playing an indispensable role in global construction, cement contributes around seven percent of annual greenhouse gas emissions owing to its carbon-intensive production process. Scientists at the University of Colorado Boulder claim to have uncovered … Continue reading Cement formed with biogenic limestone promises carbon-neutral concrete
