The stacked "concrete pieces" sounds like a bin wall, and yes they are 
calculable. Have you considered soldier beams with lagging. We have built 
quite a few over the last 10 or 15 years, as permanent structures, and 
they are performing well. We usually have the beams galvanized, but I'm 
not sure that it is necessary. For a permanent structure that also looks 
good, try precast concrete planks. The big advantage here is in the 
reduction in excavation. You basically only have to remove the dirt from 
in front of the wall.
