To ensure that your 'bonding agent' is at it's maximum, I would ensure that the bricks are:-
? perfectly clean and free from dirt/dust,
? wet, ie. been dipped in clean water and contains a significant amount of moisture,
? mortar is properly mixed with adequate water BUT not too wet nor too dry. This is sometimes hard to judge but you will know when it is correct because it is easy to trowel, apply and work.
I am not aware of interlocking bricks that could be used for a wood fired oven, especially a Pompeii. There are numerous cement interlocking pavers around but remembering that with each reducing row in your dome, the angles and shapes of the bricks will also need to change to suit to continue to be interlocked.
I always believe on the KISS principal and consequently adopt the best appropriate methods/materials for construction.

I was looking at doing the interlocking only on the first few rows and then doing the traditional methods higher up.

Thanks that was the basis of my question was with regards to expansion/movement. I was looking at cutting notches in the centre of evey brick and then adding a interlocking brick to join 2 bricks together.
If movement is a requirement in the chains then I know my idea wont work but I needed to know if movement was a requirement.

The mortar that you use and the positioning of your bricks locked them into position as they are surrounded by other structure and bricks where an arch or lintel is unsupported beneath it.

Would there be any structural reason why interlocking bricks would be a bad idea ?

inter-locking bricks
Hiya guys and gals,
Here is another newbie question and probably a stupid question but I am know to do stupid things so I may as well ask.
I know the idea of the keystone brick on every layer is to tie that layer but if it is possible wouldnt it also be a good idea to lock each brick into place wit the bricks on either side where practical and even the brick above and below if possible?
Wouldn't this make the structure stronger and reduce the need for motar inside and outside of the oven ?
Regards
