Mortars

Refractory mortar is made up of crushed refractory materials, such as alumina or silica, that are mixed with binding agents. Refractory mortar is made to be used at high temperatures without cracking or losing its shape. This is different from other types of mortar used for masonry work on brick walls in homes. Refractory mortar is used as the "glue" which holds fire bricks together in high-temperature applications like furnaces, kilns, and boilers. BM Enterprises, a trusted manufacturer and supplier in Faridabad, Delhi NCR, offers a premium range of refractory mortars designed for high-performance bonding and lining in furnaces, kilns, boilers, and other high-temperature environments.
