How are refractory mortars used when building furnace linings?

Refractory mortars are essential components in the construction of furnace linings, specifically categorized as monolithic materials. These products are designed to be formed and solidified on-site, serving the primary purpose of cementing firebricks together.1

By acting as a bonding agent, these mortars help create a cohesive and durable lining structure capable of withstanding the extreme temperatures found in industrial environments like blast furnaces and electric furnaces. While many refractory products are manufactured as preformed bricks, mortars provide the necessary flexibility to join these shapes into a unified, heat-resistant barrier.123
