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.
