Carbon-Foam concrete. It's a mixture of concrete with carbon nano structures around many small bubbles that make up 70% of the volume. The result is much lighter than concrete, needs no steel mesh and can withstand both push and pull stress.
Since it is very vulnerable to frost damage, it needs an elaborate protective cover that prevents water to enter the material if it is to be used in places where the temperature oszillates around the freezing point.
