Magnesium ions are abundant in seawater, and researchers have found a way to convert them into a magnesium-based cement that absorbs carbon dioxide.
The cement industry is currently one of the largest emitters of CO in the world.
Magnesium ions are abundant in seawater, and researchers have found a way to convert them into a magnesium-based cement that absorbs carbon dioxide.
The cement industry is currently one of the largest emitters of CO in the world, and although this seawater-derived cement is not currently suitable for steel-reinforced concrete, it could easily be adopted for BTC Number Data small-scale use in sidewalks, masonry and cobblestones .
The manufacturing process requires a similar amount of energy as regular cement , but if the electricity used comes from carbon-free sources, the overall process would consume carbon rather than emit it, keeping it out of the atmosphere.
Decarbonized magnesium-based cement.
Researchers report a process to convert magnesium ions from seawater into magnesium hydroxides and subsequently into magnesium-based cement that absorbs carbon dioxide; Magnesium-based cement has a compressive strength comparable to that of Portland cement and, although the process requires a similar amount of energy per ton as manufacturing Portland cement and is not currently suitable for use in concrete conventional assembly, the overall process would consume rather than emit carbon dioxide if the electricity powering the electrochemical processing stage comes from carbon-free sources, according to the authors.
the course of studying sustainable architecture, it became clear that there were many resources that we were not taking advantage of. People discounted the possibility that there would be enough solar energy available in cold climates.

Passive solar heating was one of them. Although it has been used for centuries, it has not been widely put into practice as a sustainable design technique.
