Safeguard Your Chimneys with the Refractory Mortars


In the masonry industry, there are a lot of things which are needed to take into consideration. Among all, the most significant one is the refractory mortar, which are designed and framed by the refractory mortar manufacturers who design them using a frame that would truly act to be protective.

These refractory mortar suppliers sell them basically to the masonry industry where these are used in only up to ¼ the or around 6 mm of the thickness. These are going to assist with the forming of the firing chamber and are intended not to be used or can also be left exposed on the hot-face.

These refractory mortars as per being declared by the refractory mortar manufacturers say that, these cannot be applied for plugging holes or big spaces and even those gaps that are present in the firebricks.


But the clay body of the refractory firebricks does face the heat. The higher mortar thickness that is applied always shrinks. This shrinkage is going to create space and increased brick movement or the gap difference between the cold state and even the state expanded by the heat on the material reheating.

These refractory mortar suppliers manage to sell these which are used in kilns and furnaces. The internal structure of these kilns is designed in fire bricks with extremely tight mortar joints or around 1-2 mm. There is the use of sodium silicate in the mortar which then reacts with the surrounding air causing the mortar to take an initial set permitting the kiln or the furnace to be constructed completely.

After that, the structure is fired into its full operating temperature and the air set mortar vitrifies, fusing to the surrounding bricks and then is converted into ceramics. 

These refractory mortars are required to construct fireboxes, smoke chambers and even those of flue linings.
