Description
| 1. Refractory mortar Description |
Refractory mortar is made by mixing a certain proportion of refractory powder, binder, and additives, water or liquid binder into a paste, also called joint filler. According to different refractory materials, ordinary mortar is mainly made of clay and high-aluminum materials. , Silica, magnesia, corundum, mullite, and zircon.
