Scientists recycle demolition waste into eco-friendly 3D printable concrete

Scientists based at the Swinburne University of Technology and Hebei University of Technology have managed to turn construction waste into a sustainable new 3D printing material. 

Using recycled concrete aggregate, ceramsite particles and desert sand, the team have been able to formulate a low-cost extrudable building material, in three different particle gradings. During initial testing, the novel concrete substitute demonstrated a self-supporting ‘skeletal’ effect, potentially lending it the strength and durability needed for deployment within heavy-duty construction applications.
