Product Details
Refractory mortar is distinguished between heat-setting property and air-setting property. Heat-setting property displays strength by heating after installation and air-setting property displays excellent strength at the normal temperature. Therefore, it has better select air-setting mortar in case of need special strength at the normal temperature and we are supplying mortar of various type that is suited to installation condition and fire-brick.
Features Of Refractory mortar
- High temperature volume stability.
- Strong binding force and good sealing.
- Good anti-permeability.
- Corrosion resistance
- It has certain degree of fire resistance.
Applications Of Refractory mortar
Installation of fire-brick and insulation brick
