Question Need the ratios for mixing refractory cement

I am making my own refractory mortar/cement as described in the Il Forno book using Fire Clay, Portland Cement, Lime, and Sand. I would like to get the ration of materials in the mix.

Parts ratio is 3x2x2x0.5, plus water
3 shovels of the gravel or crushed firebricks
2 shovels of sand
2 shovels of the cement
half shovel of lime ( hydrated lime)
This amount will require approximately 6-7 liters of water to mix the concrete.
The website this came from is Refractory concrete mixing recipe | Refractory concrete ingredients for wood ovens.

You can save much $ mixing your own.
