SL CAST NC refractory concrete cement-free mixtures
Refractory concrete cement-free mixtures are intended for heavy-duty operating conditions where increased mechanical strength and abrasive resistance are required under conditions of high-temperature exposure, as well as in repairs/lining in extremely limited time periods.

It is recommended that the maximum operating temperature of application established on mixtures be 100 °C-150 °C lower than the maximum specified temperature in a clean, non-aggressive, and neutral atmosphere of the thermal generating unit.
The cement-free mixture is comprised of two components and is supplied as a dry powder and a binder. Mixing of the mixture and the binder is performed immediately before use.
