Artificial Sandstone Roads
Artificial Sandstone roads are little more than an idea at this point in time, but Murdoch University in Western Australia is currently developing a process for solidifying sand by applying a calcium solution, bacteria and other inexpensive compounds to the sand and forcing the bacteria to form carbonate. The process is apparently capable of creating rock as hard as marble. If the process can be adapted for constructing roads, it could conceivably dramatically reduce the cost of road construction in sandy areas. The cement is known as biocement.
