Compressive strength refers to the ultimate load that the refractory can bear per unit area without damage at a certain temperature. The compressive strength of refractory is divided into normal temperature compressive strength and high temperature compressive strength. It is an important new performance index for the quality of beam refractory, and indirectly reflects the organizational structure of products, such as density, uniformity and sintering. Commonly expressed in MPa, N / mm2
The normal temperature compressive strength of refractories refers to the compressive strength at room temperature. This index has a great impact on the production, transportation and service performance of products, and also directly affects the service life
The normal temperature compressive strength of refractories refers to the compressive strength at high temperature. It determines the application scope of the product and is an important basis for the selection of refractories
