Cement

The production of concrete is a major contributor to worldwide CO2 emissions, however Nendo showcases a greener alternative with its Block-Wall House, which was part-built using a novel concrete that actually captures carbon-dioxide.

According to some estimates, the generation of the heat used to produce traditional portland cement is responsible for 5% to 8% of all human-made CO2 emissions. A new substance known as C-Crete, however, is claimed to be a much greener alternative.

Sublime Cement says it's ready to start scaling on the "world's cleanest cement," which meets industry performance standards relying on room-temperature electrolyzers in place of fossil-fueled furnaces, using a variety of zero-carbon input materials.

Concrete is one of the largest single sources of human-induced carbon dioxide emissions. Engineers at Washington State University have now developed a new method for making concrete that absorbs more carbon than it emits.

After water, concrete is the world’s most consumed material, and concrete production’s impact on the environment is significant. Researchers have discovered that an inexpensive ingredient may be the answer to reducing concrete's climate impact.

The production of the cement is a major source of greenhouse gas emissions, which is why some people have tried replacing it with fly ash. A new technique makes that fly ash more eco-friendly, resulting in concrete which is greener and stronger.

Modern concrete starts to fall apart within decades – but ancient Roman structures are still standing strong after 2,000 years. Engineers have found an inclusion that helps ancient concrete self-heal cracks, and shown how we can recreate the recipe.

Even slight adjustments to how we make cement and concrete can have a big impact on their environmental footprint, and as research continues to show, scientists working in this space are not short of ideas.

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.

Scientists at the University of Colorado Boulder claim to have uncovered a greener form of cement production by tapping into a species of cloudy microalgae that naturally produce limestone particles through photosynthesis.

The production of traditional Portland cement is a major source of greenhouse gas emissions, as the ingredients have to be heated to very high temperatures. Such is not the case with a new biocement, however, which also incorporates waste materials.

Over the past couple of years, disposable face masks have become a very plentiful form of garbage. There may actually be a use for them, however, as recent research shows that they could strengthen concrete when added to it.
