*The products are supplied according to the supplier certificate.
**Аmount of binder
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 "T" letter in the mixture grades means that the mixtures are intended for shotcreting.
The "LC" letters indicate that the mixtures are low-cement, the mass fraction of CaO in the mixture is over 1.0% to 2.5% inclusive.
The "NC" letters indicate that the mixtures are cement-free, the mass fraction of CaO in the mixture to 0.2% inclusive.
