What is Refractory Mud?

Refractory mud is also called 내화 모르타르.

It is a high-temperature resistant bonding material primarily used for refractory brick masonry, bonding the bricks together, much like cement mortar used in conventional construction.

Main Ingredients of Refractry Mud

Refractory fine powder (high-alumina, silica, magnesia, etc., selected according to the brick material)

Binder (such as aluminate cement, phosphate, water glass, etc.)

Appropriate additives

Features of Refractry Mud

High temperature resistance (above 1500°C)

High bond strength, ensuring the integrity of the furnace lining

Resists cracking after drying and firing

Ensures airtightness and corrosion resistance in brick joints

Applications of Refractry Mud

Used for laying various refractory bricks (such as those in blast furnaces, hot blast furnaces, glass kilns, cement kilns, electric furnaces, etc.)

Can also be used to repair cracks or gaps in refractory linings

In simple terms, refractory mortar is “high-temperature-resistant cement” and serves as the adhesive used in refractory brick laying.
