Researchers at Oregon State University have developed a quick-setting, environmentally friendly alternative to concrete for 3-D printing homes and infrastructure, aiming to address the global housing crisis and reduce carbon dioxide emissions from cement. This innovation could help speed up construction projects by eliminating the long curing time and structural supports required for traditional concrete, potentially making a significant impact on the 8% of global emissions attributed to cement production. Climate solutions experts should take note of this promising development in sustainable construction materials.
