If you’re compacting the cement mix, instead of pouring it wet, why not make the mold 10 feet deep? Then as you fill it up (after compacting each sub-layer) you’ll poop out bricks automatically. You just have to cut them off with a thin steel cable, piece by piece as they come out the other end of the mold. Adding new cement, and compacting that cement, become the force that helps push the rest of the cement forward in the assembly. Make sense?
In theory this sounds good, but doing it by manual means won't work. The concrete mixture is not that plastic to accomplish that. Using other type of aggregates will work, as the lime sand used for bricks, but they need to be cooked afterwards
