4.Application:

Therefore it is suitable to make refractory concrete as a binder. Depending on the refractory aggregates (fireclay, high alumina)which are used, the refractory concrete made of the cement can be used below 1400 centigrade.If it is used in construction, attention given in the appendix GB201 must be followed.
