Fireclay mortar
Fireclay mortar is unshaped fireproof material, which is the combination of powder materials and bonding agents. Fireclay mortar is mainly used as the joints and coating materials in building refractory bricks. When fireclay mortar is used as joints materials, the quality has great effect on the building. Fireclay mortar can adjust the tolerance of the fireclay bricks sizes and irregular shape, make the building tidy and balance the load. Fireclay mortar also builds a strong and well-knit entity to resist external forces, prevent the damage by intrusion of gas and molten liquid. When fireclay mortar is used as coating, Fireclay mortar decides whether the protection layer can give full play to its effectiveness and has a very close relationship to prolong the working life.
Fireclay mortar is used by adding water or aqueous solution. Fireclay mortar must have well liquidity and plasticity to facilitate the construction. Fireclay mortar should has necessary bonding performance in the construction and after the construction to ensure the building and ground to be a whole in order to has the ability of anti-erosion of gas and slag ; Fireclay mortar should has the same/equivalent chemical material with the building and bottom in order to avoid earlier damage to fireclay mortar and chemical reactions between fireclay mortar and building. Fireclay mortar should also has similar thermal expansion with the bottom and the building , so as to avoid each other detachment and coating rupture.It should has stable volume, in order to ensure the protection and the building integrity .
