I am making my HT oven at the moment and have a question on refractory cement. Basically should I cement (mortar really) my bricks together or leaves them as a dry stack? I am using K23 bricks and have an appropriate high temp refractory cement but I have not found if I should actually use it or not. The bricks are all cut and fit together well dry and if I can make a tight fitting metal frame they will all stay snug I believe. Having the stuck together would reduce the need for such a precise fitting exterior to hold everything tightly.
Pros and cons?
