【 摘 要 】

Aim. The article presents the results of a study of heat-resistant binder based on Portland cement with the addition of a local mill ground minerals.Methods. Activation is carried out on a planetary mill "Activator - 4M". Activation of the binder increases the strength of heat-resistant concrete by increasing the reactivity bundles "Portland is the active fine additive" to the mechano-chemical additive.Results. It is determined that the mill ground additives result in the formation of low-melting and thereby reduce the temperature of the use of heat-resistant concrete with Portland cement binder.Conclusion. It is proved that high mechanochemical strength refractory concrete samples on activated binder is caused by the process of increasing the chemical activity of the materials included in a bundle of "Portland cement is the active fine additive" which creates favorable conditions for hardening of heat-resistant concrete.
