Mortars

Refractory mortar is made up of crushed refractory materials, such as alumina or silica, that are mixed with binding agents. High-temperature cement 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 is a leading manufacturer and supplier of high-quality refractory mortars in Faridabad and the Delhi NCR region. They meet the stringent needs of industries operating in extreme temperatures.
