That’s not really what I’m proposing. It’s not solid concrete, it’s a concrete based foam, with small fiber reinforcement. The point is it’s quite lightweight,

That’s not really what I’m proposing. It’s not solid concrete, it’s a concrete based foam, with small fiber reinforcement. The point is it’s quite lightweight, both the materials and finished pieces are movable by people without heavy equipment outside of a pickup truck. Basically it requires a small portable cement mixer, a foam generator and a pump. As an example, one could layer it over defensive fortifications rather quickly, or fabricate human movable slabs which could be placed over trenches. It can even potentially even on vehicle roofs/sides, providing some degree of protection from drones grenades and suicide drones. Even a fucking tank isn’t going to protect you from a direct artillery shell hit.
