Could anyone give me a considered opinion on the idea of building larger E/G structures from smaller pre-cast blocks on the Lego priciple ?
Is there a unanswerable disadvantage in this approach ?
I'm assuming that the interfaces would be suitably prepared, though I'm not sure what that would entail.
I have in mind a block design that would use protrusions greater in size than the largest aggregate, so that there would be no simple cleavage plane through the assembly.
The idea is that with a smaller block, the problems of air entrapment/packing fractions/curing might more easily be overcome for the diy builder.

It's like doing jigsaw puzzles in the dark.
Enjoy today's problems, for tomorrow's may be worse.
