This study demonstrates a novel means of carbon capture and storage (CCS) in ultra-high performance concrete (UHPC) to reduce its carbon footprint. A two-pronged approach of developing eco-friendly UHPC was employed by 1) replacing cement in the mix with ground granulated blast furnace slag (...
Carbon capture is essential to reduce the impact of human carbon dioxide emissions on our climate. Researchers at the University of Tokyo and Nagoya University in Japan have developed amethodto confirm whether carbon in concrete originates from the raw materials, or from carbon in the air which h...
Carbon capture and utilization for concrete production (CCU concrete) is estimated to sequester 0.1 to 1.4 gigatons of carbon dioxide (CO2) by 2050. However, existing estimates do not account for the CO2impact from the capture, transport and utilization of CO2, change in compressive strength in ...
Soletair Power, founded in 2016, uncovered the potential for technology to reduce a building’s carbon emissions by capturing CO2 from its ventilation system and using it in the production of fuel or concrete, for example. Why capture CO2 from buildings? CEO Petri Laakso explains the multiple ...

This isn't the first attempt to capturecarbon emissionsfrom power plants. It's been done before, but the challenge has been what to do with the carbon dioxide once it's captured. "We hope to not only capture more gas," DeShazo said, "but we're going to take that gas and, instead...

Interactions of carbon-containing fly ash with commercial air-entraining admixtures for concrete The microwave absorption characteristics of both powdered and rectangular blocks of an electrically conductive concrete were measured and compared to a normal Portland cement concrete in a multimode cavity. The...
A similar process called carbon capture, utilization, and storage (CCUS) converts some of the captured carbon into concrete, carbonate rock, plastics, and biofuels before storing the rest. CO2 is a chemical compound that is formed from the combustion of petroleum, natural gas, coal, biomass, ...
The protective concrete layer—normally required to protect the steel reinforcement from corrosion—can be reduced to several millimetres, resulting in thinner building parts and a reduction in the amount of concrete used [8,9]. For example, the thickness of a steel reinforced concrete façade of...
