Revolutionary “true zero carbon” cement uses electrolysis, not furnaces

Traditional concrete manufacturing processes result in a ton of CO2 for every ton of cement produced – and since we’re talking about somewhere around 4.1 billion tons globally just in 2022 – more than half of that in China alone – cement is a massive c… Continue reading Revolutionary “true zero carbon” cement uses electrolysis, not furnaces

Low-cost additive turns concrete slabs into super-fast energy storage

MIT researchers have discovered that when you mix cement and carbon black with water, the resulting concrete self-assembles into an energy-storing supercapacitor that can put out enough juice to power a home or fast-charge electric cars.Continue Readin… Continue reading Low-cost additive turns concrete slabs into super-fast energy storage

Cambridge 3D prints game-changing smart concrete structure

Working with private industry, the University of Cambridge has gone one step beyond 3D printing with a concrete infrastructure unit that was not only made in an hour, but incorporates sensors to make it self-monitoring and, one day, self repairing.Cont… Continue reading Cambridge 3D prints game-changing smart concrete structure

Light-activated concrete scrubs air pollution out of traffic tunnels

Traffic is among the biggest sources of air pollution, but what if the very roads they drive on could help clear the air? Engineers in Korea have now demonstrated that photocatalytic concrete can help reduce pollution in tunnels.Continue ReadingCategor… Continue reading Light-activated concrete scrubs air pollution out of traffic tunnels

Discarded diapers lay the foundation for future homes – quite literally

Finding low-cost, sustainable building materials is important for the environment and providing access to affordable housing. Researchers have created a composite building material by replacing sand in concrete and mortar with a common, non-degradable … Continue reading Discarded diapers lay the foundation for future homes – quite literally

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

Shell Wall tech claimed to reduce weight of concrete walls by over 70%

3D concrete printing (3DCP) technology is already known to offer a more efficient approach to constructing buildings. A new type of 3DCP, however, is said to be even better, resulting in walls that are a claimed 72% lighter than their conventional coun… Continue reading Shell Wall tech claimed to reduce weight of concrete walls by over 70%
