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.Continue ReadingCategory: Materials, ScienceTags: Cement, Concrete… Continue reading ‘ZeroCAL’ cement production process takes CO2 out of the equation
Most of us have made paper airplanes at one time or another, but rather than stopping at folded paper, [VirgileC] graduated to 3D printing them out of PLA. Then the …read more Continue reading That’ll Go Over Like a Cement Airplane
A new type of carbon-neutral concrete has been commercially used for the first time, in a high-profile skyscraper being built in Manhattan. The binder utilized in the concrete is made of granite instead of traditional greenhouse-gas-emitting limestone … Continue reading Carbon-neutral granite-based concrete finds use in towering NYC skyscraper
A pair of Princeton engineers have developed a new kind of concrete that promises more than 5 times the damage resistance of the usual stuff, by poking holes in its structure.Continue ReadingCategory: Materials, ScienceTags: Concrete, Princeton Univers… Continue reading Hollow concrete mimics human bones for 5x better toughness
Back in 2021, researchers came up with a recipe for greener concrete that had building waste and CO2 among its ingredients. Now the same team has used rubble from a demolished school and the greenhouse gas to produce bricks to build new structures.Cont… Continue reading New greener building bricks made from demolished school and CO2
A new material tackles the carbon problem of concrete production and usage by employing a pretty unusual workforce: cyanobacteria. The bio-cement these micro-organisms help to produce harnesses a process that’s existed in nature for 3.5 billion years.C… Continue reading Carbon-capturing concrete alternative driven by photosynthesis
Although most energy storage solutions on a grid-level focus on batteries, a group of researchers at MIT and Harvard University have proposed using supercapacitors instead, with their 2023 research article …read more Continue reading Carbon–Cement Supercapacitors Proposed as an Energy Storage Solution
Last year, researchers from RMIT University in Melbourne, Australia, found that replacing up to 15% of the sand ordinarily used in concrete with waste coffee grounds made it 30% stronger. It’s a case of killing two birds with one coffee bean: the produ… Continue reading Super-strong coffee-reinforced concrete gets real-world test
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 purifies iron but produces “reactivated cement” as a … Continue reading ‘Absolute miracle’ breakthrough provides recipe for zero-carbon cement
Coal ash is abundant around coal-fired power stations. In fact, that might be considerably understating things – globally, power stations produce around 1.2 billion tonnes annually, and in Australia coal ash accounts for nearly 20% of all waste. It’s a… Continue reading Long-life low-carbon concrete switches 80% of its cement for coal ash
