Originally Duro-Crete was and is a trademark of Jackson Minerals Inc. headquartered on Mars in the Sol System. The Original JMI-Duro-Crete is manufactured as pre mixes since 2221. Duro-Crete soon however became a household name for any sort of extremely durable concrete.
Duro-Crete is harder and denser than regular concrete and relies on Carbon Buckyball Nano fiber lattice, that can be directionally adjusted by applying a current before it hardens and can be used like reinforced concrete without the steel.
Of course Duro-Crete can be reinforced just like regular Concrete, for even more daring architecture.
Space Port Surfaces are often made of Duro-Crete.
