DENSE REFRACTORY CASTABLE 2800 ° F - 55 LBS

Excellent catch-all, this refractory castable has insulating capacities but also provides an acceptable mechanical resistance. Ideal for making an oven or a fireplace. 

Baking: It is important to bake the refractories slowly to prevent them from cracking or bursting. After curing for 24 hours (drying of the fresh concrete), the refractory can be baked gradually at a rate of 25°C/h, stopping at 150°C, 315°C and 540°C for stages of a few hours (1h / inch of material).

Density: 126 lbs / ft3.
