Web29. aug 2014 · A higher porosity refractory will typically have excellent insulating properties but a lower strength, density and resistance to corrosion. A lower porosity refractory will typically be stronger, with less resistance to corrosion, but it can lower the thermal shock resistance. 5. Thermal Shock Resistance WebA reduction of the relative density by the generation of additional porosity results on the one hand in a lower thermal conductivity, however, it generally leads to a degradation of the mechanical properties and the abrasion resistance. Dense materials with low thermal conductivity are frequently susceptible to thermal shock.

"WebTap density is the maximum density of a dry refractory blend that has been vibrated or shaken to maximum compaction. There is a particle distribution blend that produces a maximum bulk density. This blend, when mixed with a small amount of binder, will produce a product with cement like consistency at rest. Vibration will make it flowable. " - Refractory density
