Lightweight Insulating Castable Description Lightweight insulating castable is monolithic refractory made from lightweight refractory aggregate, powder, binding agent and additives. Lightweight insulating castable is usually worked by casting method, or gunning method, spraying coating method, that’s why it is also called lightweight concrete, or lightweight coating mix, lightweight unshaped refractory. As lightweight insulating castable has good workability and fast working speed, especially for inner lining with complex structure and shapes, the advantages of lightweight insulating castable is more significant. Besides, light insulating castable has low thermal conductivity and low thermal capacity, it is energy-saving, so it is widely used in high temperature projects as insulating material. Lightweight Insulating Castable Type Lightweight insulating castable is usually named by its aggregate composition, for example, expansile vermiculite castable, expansile perlite castable, lightweight high alumina castable, light mullite castable, lightweight silica castable, etc. The performance of light insulating castable is mainly decided by the performance of lightweight aggregate and binding agents.
