type of concrete
From the WFO board

I have just completed a 2 inch insulated slab on top of 4 inches of rfd. concrete. Reinforced.
Can I use 2" regular rfd. concrete on top (for the base of the hearth), or does it it require re factory concrete, or can I place the firebricks upright 4.5" on top of the vermiculite insulated slab.
My oven is small 40" by 30"
Thank you a lot.
