Fast-Curing Environmentally Friendly Concrete Substitute

developed

Researchers at Oregon State University have developed a quick-setting, environmentally friendly alternative to concrete that can be rapidly 3D printed for homes and infrastructure. The clay-based material cures as it is extruded, can be printed across unsupported gaps, and achieves residential structural concrete strength in just three days. It consists largely of soil infused with hemp fibers, sand, and biochar, resulting in a much smaller environmental footprint compared to traditional cement-based concrete.
