How is the bulk density of refractory castables defined? Why is there a difference in the bulk density of refractory castables for refractory materials in Rongsheng Refractory?

The reason why the refractory castable has a bulk density is because the solid volume, the opening and the closed pores are contained in the refractory material, and the mass per unit volume in such a state is called the bulk density of the refractory material.

When using the castable to build the boiler lining, most people will show the required bulk density of the castable, because the bulk density of the refractory castable is not negligible when purchasing refractory castables and refractory castables.

The technical department of Rongsheng Refractory pointed out that the volume density of different types of refractory castables is also different. In the actual use process, we should pay attention to distinguish the bulk density and physical and chemical indicators of refractory castables.
