Properties of Castable Refractories
Cold crushing strength is a measure of the refractory's strength and durability. As refractory falls within the domain of ceramic materials, it tends to fail in brittle fracture. In addition, castable materials naturally contain a large population of flaws in the form of porosity and surface cracks. These materials tend to be very strong in ...
