Product Description

Refractory mortar is used to hold furnace building materials such as refractory bricks or blocks together. Refractory mortar is a mortar that is prepared in the factory to withstand high temperatures and meet all codes. Refractory offers an alternative to traditional mortar mix and is designed to be more durable and longer-lasting despite use. In addition to its durability, refractory mortar is valued for its ease of use. The mortar mix is typically a combination of clay, aggregates, and binders, and requires very little if any mixing. Refractory mortars basically eliminate the possibility of improper mixing ratios and are designed to be easy to apply and work with. Because the mortar is prepared in a factory, it is guaranteed to meet all codes and withstand the extreme heat of a fire, use after use.


1. plasticity is good, construction is convenient; 2. the bond strength is big, the corrosion resistance ability is strong; 3. the fire resistance is high, up to 1650 degrees C + 50; 4. good resistance to slag resistance; 5. thermal spalling is good, the use of long cycle.
