Ultra-light material providing very high insulating properties. Excellent material for making the insulating lining behind dense concrete.

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: 26 lbs / ft3.
