Default Help with DOME please someone!

Greetings Brothers and Sisters,

I am having some issues in regards to the dome. We made a wooden support structure that took up about 1/3 of the oven to help lay the brick to form the dome. We used a 10:10:1 sand,clay,portland and let it dry with a kerosene heater for about 1 week (our weather is about 30-40 degrees this whole winter) until we removed the support structure. When we removed the wooden support structure part of the dome shifted and cracked. We found it much too loose and easily pryed it apart with our hands very easily. For your information this oven is on a mobile truck and will be stressed. We are thinking a dome made of brick and motar probably isnt the best option. Do you think casting the dome would be best and strongest for our application"? If so can we cast a 3-4" dome using your refractory motar recipes? Can we use some remesh to reinforce the dome? Or will it expand and contract too much for metal reinforcement? And will it adhere easily to the walls which are made out of firebricks? Thanks for your comments

Regards,

Blare
