Evaluating Refractory Properties - Resco Products

Refractory Properties. Refractory properties are broken into mechanical physical properties and high-temperature properties. Typically, refractory materials are characterized by density, strength, and response to heat treatment. Certain physical properties are also measured and recorded during manufacture and serve as a basis for quality control.

Refractory Concrete Tutorial - Recipe and Instructions

But saying that, even though it''s refractory, still it is not so straight forward to cast large hot face section/s out of it. It is different to fill holes and awkward spaces with castables. Large blocks tend to crack as a result of something called heat differences in material, or temperature differences in material in other words, which is a very powerful natural phenomena.
