Concrete innovation promises greener future with deeper CO₂ absorption

Concrete innovation promises greener future with deeper CO₂ absorption

Concrete is everywhere. As the world's most widely used construction material, it forms bridges, buildings, roads and other infrastructure. But concrete, and its primary ingredient, cement, are responsible for roughly 8% of the world's CO2 emissions. In fact, if the cement industry were a country, it would rank as the fourth largest greenhouse gas emitter, behind China, the United States and India.

In order to reduce the weight of concrete slabs and the use of polluting materials, such as concrete, BubbleDeck has developed a revolutionary technique using HDPE balls.... The BubbleDeck article, an invention to build slabs with less concrete, 30% lighter appeared first on NeozOne.

US engineer’s concrete breakthrough may turn buildings into carbon-sucking structures | The new method, internal-external CO2 curing, increases carbonation depth, improving the material’s strength and durability

An innovative cement substitute developed in Eindhoven uses sea water and electricity to capture CO2 rather than emit it, potentially revolutionizing an industry responsible for 8% global emissions A team of researchers from Eindhoven University of Technology (TU/e) has developed a revolutionary substitute for cement that, instead of emitting carbon dioxide, captures it.This advance could transform the construction sector, since traditional ceme…

Studies show that cement is the second most used material after water and, in addition, it is very polluting. That is why Gemma Rojo, from O Saviñao, looked for a way to reduce its use in self-compacting concrete in her doctoral thesis. This work earned her the Anci 2024 award.

Researchers at Northwestern University in Evanston and Chicago are replacing sand, which threatens to become a shortage worldwide, in the production of concrete with a synthetic material that binds carbon dioxide (CO2) taken from the air. Thus, CO2 emissions in the production of cement, another ingredient for concrete, are more than compensated. Building with concrete becomes a CO2 sink, which means that the climate is relieved. Because the synt…
