Australia: Researchers at Royal Melbourne Institute of Technology (RMIT) have developed a cement-free building material using cardboard, soil and water. The material uses recycled heavy cardboard cylinders as form-like confinement, creating comparable strength to that of high-performance concrete. By eliminating the need for cement, it reduces costs by 66% and embodied CO2 by 75% compared with concrete, according to the developers. The ability of the material to be made on-site using local earth and water further reduce its transport costs and impacts.
Construct Connect Daily Commercial News has reported that the team are open to forming industry partnerships for the commercialisation of their new material.
