how to make refractory brick mortar

Material selection
12~16% silicate cement
10~15% powdered refractory mud
5% silica powder
20~30% quartz sand
30~50% river sand
The balance is water

Production steps
Mix the above materials evenly according to the proportion; add water and stir to the appropriate construction consistency

Precautions
Construction should be carried out in a suitable environment to avoid high or low temperature affecting the performance of mortar
Proper maintenance should be carried out after construction to ensure the strength and stability of the mortar

how to use refractory mortar​

1. Prepare refractory brick mortar, water, mixing bucket, agitator and other tools
2. Mix refractory mortar and water evenly, and pay attention to controlling the viscosity
3. Construction should be carried out in a dry, windless and rainless environment
4. The surface needs to be cleaned before construction to ensure that it is dry, oil-free and free of debris
5. Use professional tools for construction, and pay attention to the thickness, direction, density, etc. of the mortar coating
6. After the construction is completed, the density, bonding strength, thickness and other indicators of the mortar need to be tested
7. Avoid cracks after high temperature, and refractory aggregates and powders can be added
8. Avoid moisture hardening, quick drying in the sun, freezing at negative temperatures, etc.

How long is the drying time of refractory mortar?

The drying time of refractory brick mortar usually depends on a number of factors, including ambient temperature, humidity, and the thickness of the mortar. In general, the initial drying time of refractory mortar at room temperature is about 24 hours, while complete drying and curing may take 7 to 14 days.

In practical applications, it is recommended to follow the specific drying guidelines provided by the manufacturer to ensure the performance and durability of the refractory brick mortar.
