In a new study published in the journal Open Engineering, two researchers from the University of Manchester in England demonstrate the effectiveness of potato starch as a binder to create the novel "StarCrete." StarCrete, a material made of potato starch, salt and simulated Mars or moon dirt, is twice as strong as conventional concrete, its creators say. So, the strength and durability made possible by a lightweight potato starch-based concrete mix holds high potential over conventional materials when it comes to otherworldly construction, the study team says.
