Note on the Tensile Strength of Refractory Materials

JSGT 1920 V04 T138-T140(3 pages)

Whilst a considerable amount of attention has been paid to the investigation of the resistance to crushing of refractory materials, and crushing tests are included in many specifications, I have not been able to find any references to measurements of the tensile strength of refractories. The matter is of importance, for in modern glass furnaces, working at high temperatures, failures are generally to be attribute to, the fact that the materials are in tension rather than under load. I propose to illustrate this fact by means of a few examples.
