SL ISOCAST® refractory concrete thermal insulation mixture

Refractory concrete thermal insulation mixtures are intended for obtaining concrete thermal insulation mass and production from it of refractory concrete thermal insulation products used in the form of monolithic lining or in the form of structural lining panels, for fencing the working space of the furnace unit and for protecting the metal frame of the furnace from excessive overheating, as well as in tubular reforming furnaces, pyrolysis furnaces, in metal heat treatment furnaces, in non-corrosive and neutral environments, for refractory concrete product manufacturing, as well as for obtaining monolithic lining in hard-to-reach places without the use of vibration.

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 products are supplied according to the supplier certificate.

**The SL ISOCAST® 0.8-1100 SE mixture consists of three components and is supplied as a dry component and a binder. The amount of binder is 65%; the total amount of dry component is 35%, of which the bulk component (mixture) is 53.5% and the fibrous additive is 46.5%. Mixture dry component: the bulk component and the fibrous additive shall not contain any foreign inclusions. The total curing time of the resulting mass is 48 hours. Mixing of the dry component and the binder is performed immediately before use.

Legend:

T - the mixture is intended for application by shotcreting

SE - self-expanding mixture

SF - enhanced spreadability
