Cob wouldn't be my first thought, no. I would look at something whose material properties are better known under tension and compression.
You have the clay road road base mix. Why not make up a dry rammed earth mix and ram that down into the forms? If you add about 5% portland cement or equivalent for stability, it
should do exactly what you're looking for.

A human being should be able to change a diaper, plan an invasion, butcher a hog, conn a ship, design a building, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take orders, give orders, cooperate, act alone, solve equations, analyze a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, die gallantly. Specialization is for insects.
