What Are Monolithic Refractory Materials?

Monolithic refractory materials are unshaped refractories supplied in granular or powder form and installed directly at the site without pre-firing. These materials provide joint-free linings, faster installation, and better resistance to thermal shock and abrasion compared to conventional bricks.
