Effect of density on change in strength of refractories

Refractories Aims and scope

Conclusions

It was experimentally established that the spread in strength values of oxide refractories is mainly due to the spread in apparent density (bulk density). This phenomenon cannot be considered in isolation from density characteristics. There exists a direct relationship between the individual values of apparent density and maximum compressive and tensile strength for individual series of specimens. The contingency factor has no decisive value in explaining the various strength factors of refractory materials.

To improve the production technology of refractory products it is necessary to take into account those factors which affect the changes in the density of individual specimens and throughout the volume of each specimen.
