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
1.Good anti-permeability.
2.Corrosion resistance
3.It has certain degree of fire resistance.
