Experimenting with permanent road bed.

No need for a sharp saw Jon - because it wont be for long.

This assumes we're talking about the same block. The aerated block I'm talking about is made from concrete that uses volcanic material and is put in a vacuum form to be puffed up into the full-sized block? If so, it's about two or two and a half times what was quoted above, depending on your source.

Sorry, my point was that these blocks are not such a price product here in the UK as they are far more common

Hence we simple Brits were struggling to understand why you saw them as expensive.

I have made Viaducts with them, on the Ruschbahn we had a very large one indeed. Utilised them with Steel Rods in the middle to get the 3ft High slender pillars around 3-4 inches wide. But as Phillip says much smaller than 1 inch would be a little on the brittle side. If you are going to saw them quite narrow would suggest you do it on a firm bench with perhaps the block held by Clamps with wood to protect the Block, then allow only a little over the edge say not much more than you wish to cut with a good sharp saw.

Many thanks Jon and Phil, I think 1" should be ok, time to experiment
