Refractory mortar consists of refractory powder, binder, and additives. Used as a joint material for refractory masonry. According to the material, it can be divided into high alumina, silicon, Alumina silicate refractory mortar,Alkaline refractory mortar,Silicon carbide and carbon refractory mortar and magnesium refractory mortar. It is mainly used for masonry of various kiln fire bricks.
Refractory Mortar Features:
1. Good plasticity and convenient construction;
2. High adhesive strength and strong corrosion resistance;
3. High fire resistance, up to 1580~1670ºC;
4. Good slag penetration resistance;
5. Good thermal flaking property.
6.low drying and firing shrinkages
Refractory Mortar Application:
Refractory mortar is mainly used in all kinds of industrial kiln built with clay brick. For example, it is used for laying furnace top, regenerator, combustion chamber, etc., for the body of blast furnace, etc., and it can also be used for repairing the wall of industrial kiln.
