Cold crushing strength and high temperature crushing strength of refractory brick

Cold crushing strength

Cold crushing strength is the ultimate load per unit area of dense shaped refractory products can withstand without damage at room temperature.

The cold crushing strength of pressure-resistant refractory products has a great impact for the production, transportation and use performance, so higher cold crushing strength is better.

The high crushing strength indicates that the processed quality is good, structure is uniform, and well sintered.

High temperature crushing strength

High-temperature crushing strength is the refractory products under the specified high temperature conditions, the unit area can withstand without damage.

The high temperature crushing strength of refractory products determines the use scope, which is an important basis for the use of refractory materials.

High temperature crushing strength indexes are also meaningful to unshaped refractories, especially refractory castables and fire-resistant plastic materials. So the high temperature crushing strength is more important.
