GELCAST, NXGEL
No-cement refractory castables
Cement-free refractory concretes (NCC) do not contain cement, and binding is achieved through additives such as silicates, aluminates, or phosphates. They are intended for applications at very high temperatures, where traditional cementitious concretes could degrade. Linings made from cement-free concretes are characterized by, among other things, high resistance to thermal shocks and chemical corrosion.
The proper selection of refractory material for a specific application requires an appropriate analysis of the device's operating conditions. Before choosing the type of material, contact our specialist to confirm its suitability for your furnace.
