An exhibition called Wetland Lab proposes a cement alternative made from salt.
The proposal led by the waiwai research and design agency offered up a prototype of a salt-based cement material made from recycled industrial waste salt solutions. The material uses salt as a binding agent. Then, it relies on a crystallization process inspired by the sabkhas or crystalline salt formations found in the wetlands of the United Arab Emirates.
This cement alternative could reduce the construction industry’s carbon footprint and environmental impact. Moreover, Portland, Oregon cement used in construction is responsible for 8% of global carbon dioxide emissions. So sustainable architecture has been looking for ways to reduce traditional cement use in new builds.
Will this innovation make its way to the construction industry worldwide? Let us know your thoughts by commenting below.
