The world may be running out of sand suitable for concrete. Researchers are therefore testing a possible solution for using desert sand as a material. Ren Wei and several researchers at NTNU and the University of Tokyo have made a prototype of a new material: botanical sand concrete. It combines desert sand with plant-based additives and is made by pressing desert sand and tiny pieces of wood together, along with heat. Their paper is published in the Journal of Building Engineering.
Can desert sand be used to build houses and roads?
