Mortar MMK-77

Mortel MMK-77 is a highly refractory dry mix for preparing masonry and repair mortars when working with high-alumina and corundum-containing refractories designed for use in high-temperature areas. The composition ensures the formation of a dense and heat-resistant joint that is resistant to prolonged heating and cyclic thermal loads. The mixture is characterised by fine grinding and uniform structure, easily mixed with water and forms a plastic mortar, convenient for thin-joint masonry. After hardening, the mortar forms a strong refractory bond with good resistance to cracking, thermal shock and staining under the influence of gas flows. MMK-77 is used for lining furnaces, heating and thermal units, firing chambers, drying installations and other thermal units where high-alumina refractory products are used.
