australian scientists have demonstrated a new building material made from cardboard, soil, and water. it is suitable for low-rise buildings and has the potential to make construction more environmentally friendly and cost-effective.
this material emits one-quarter of the carbon dioxide compared to concrete and costs one-third less. moreover, it can be recycled.
the manufacturing process is simple. at the construction site, a mixture of soil and water is directly compressed into cardboard molds. the strength depends on the thickness of the cardboard tube, and adding carbon fiber can provide strength comparable to that of concrete.
the research team is currently looking for partners to apply this technology to large-scale construction. professor xie yiming said that this technology paves the way for the development of environmentally friendly architecture. another advantage of this technology is that it can simplify the design process by creating natural heat regulation functions within buildings.
