Grancrete (pdf ) by Argonne offers a step up from the spray-forming concrete products like Shotcrete available today. The ceramic composite of locally available, biodegradable ingredients is stronger than concrete. Since the material is sprayed onto a simple frame made of Styrofoam or locally woven fibers, we know the process offers a wide architectural formal vocabulary, allowing multiple translations of the material into its specific local customs. The material is currently going through its final testing prior to worldwide distribution for cheap housing.
